Interesting Facts about Bronze the Country’s Top Bronze Tubing Suppliers Want You to Know

facts about bronze

Bronze is one of those metals that most people have heard of at least once. It’s very popular, much like gold and silver. Despite its popularity, bronze is quite elusive to most people, and that’s mainly because they don’t get to see objects made of bronze on a regular basis. In fact, bells of old churches and statues in museums are probably the only things that they can imagine when thinking of bronze. It turns out, there’s more to bronze than most people know. If you want to learn more about bronze—maybe you are thinking of using bronze tube, bar, or sheet for your own project—check out the interesting facts below.

It Isn’t Mined

All metallic elements are extracted from the earth through mining. Although bronze is undoubtedly metallic, it’s not an element. Rather, it’s a compound of two elements—copper and tin—which, unlike bronze, are mined. Those two elements are mixed together by smelting in a foundry to produce bronze. In other words, bronze is a manufactured metal. Sometimes, to improve the properties of bronze, a miniscule amount of other metals, such as aluminum, manganese, nickel or metalloids, such as arsenic, phosphorus or silicon, is added.

It Is Not Magnetic

One of the biggest misconceptions about metals is that all of them can be attracted to magnets. Bronze is one of those that cannot. So if you want to check whether or not a certain piece of furniture is genuine bronze, you can simply try to stick a magnet on its surface. If the magnet sticks, then it’s probably made of iron or nickel coated with bronze-colored paint. Many scrap yards do the same when segregating all the metals they can recycle.

It Doesn’t Rust

As an alloy of two metals that don’t rust, it’s pretty obvious that bronze doesn’t rust as well. But this doesn’t mean it doesn’t react to oxygen, which is the primary catalyst of rust. It does react but in a much different way from how iron and ferrous metals react. Instead of forming rust, it forms a patina on its surface. This is a layer of material that grows thicker over time, further improving bronze’s protection against the elements.

It’s Hard to Melt

If there’s one weakness you would want to improve in metals, it’s their low resistance to heat, thanks to their high conductivity. But some metals like bronze don’t heat up fast. Bronze’s melting point is about 950 °Celsius (1,742 °Fahrenheit), which makes it a great material for applications that involve extremely high temperatures. It also has a property that allows it to slowly expand while cooling down, which is helpful for sculpting.

It Can Be Welded

Those who are new to metalworking and are looking for the right metal to use in their projects are reluctant to opt for bronze. They keep asking, “Can bronze be welded?” Well, it can’t be welded using standard brazing techniques. Special brazing, which involves the use of dedicated filler bronze rods, is needed to connect bronze surfaces. The process is similar, though—melting the surface a bit to allow it to weld with another surface as it cools down.

There are many other facts about bronze that you should know before opting to use it for any of your projects. Knowing a thing or two about the metal you are planning to use could help in finding the right grade and amount. Copper alloy experts and bronze tubing suppliers like Rotax Metals can help you find the perfect materials, and they have a large inventory that can supply you with as much metals as you need.

Some Facts about Metals Before Buying from Aluminium Bronze Suppliers

Metals in interior design never go out of style. They remain high in demand because they are simple to incorporate in any design element, and can effectively elevate the aesthetic of a room almost immediately.

As easy as it is to do right, however, it can also be just as easy to get it wrong. Professionals make sure to carefully take note of the desired theme to avoid adding in items that could clash with it. A rustic-themed interior, for example, would predominantly have wood materials. Metals can be incorporated too, but certainly not by a lot, and depends on the kind that will be used. Bronze is a good option, to go with the wood aesthetic, for example, because it does “age” beautifully with its patina.

Before you go looking where to buy bronze metal, here are some helpful information on bronze metal and how you can work them into your designs for a simple yet sophisticated look.

Composition and Properties

Technically speaking, bronze is a type of alloy resulting from a combination of copper and another type of metal. The most common pairing is usually copper and tin, although there are many possible varieties. Other elements contained in bronze may include aluminum, arsenic, manganese, nickel, silicon, or zinc.

Bronze takes on a golden appearance, which is why it is a good substitute for gold. It is also hard but malleable, thus making it a good option for metal art, among its many other functionalities. In particular, bronze is a great choice for sculpture casting because it expands by just a small amount when its form solidifies from a liquid state. This helps better fill the mold, allowing the casting mold to be filled precisely.

Apart from that, it also does not generate sparks when used to strike against a hard surface. It also has considerably low friction, especially when compared against other metals. This makes it a good alternative to steel, especially when working with or around flammable materials.

Unique Patina

The trademark characteristic of bronze is the patina or discoloration. This is actually a result of exposure to air. The oxidation only affects the outermost layer of the bronze metal, though, which means that the rest of the material remains in its original state.

The patina starts out as copper oxide, and then later on transforms into carbonate. The oxidation process itself is no threat to the metal, and in fact even protects the inner layers against corrosion. What you should be careful about when using bronze are the chlorides, such as those in sea water. This can lead to the formation of copper chlorides, which in turn can give rise to corrosion that can destroy the metal. This occurrence is otherwise known as the “bronze disease.”

Care & Maintenance

If you prefer to have the bronze metal pristine and without patina, clean it regularly with the following steps. Simply use warm, distilled water to rinse the metal, and then put on paste made of baking soda and lemon juice. Gently clean with a brush; ideally, you should use the one with soft bristles so that it doesn’t scratch the surface of the bronze material. An alternative mixture for the paste could also be flour and salt mixed with white vinegar. Once you’ve scrubbed the metal with the paste, leave it on for 20 minutes before rinsing.

If the material has already developed the bronze disease, you will have to clean it a lot more frequently. You will need to soak it in a sodium sesquicarbonate solution (5% or less), changed every week. Again, always remember to use only warm, distilled water for rinsing. You’ll know the treatment has worked once the pH level turns neutral.

One thing you have to keep in mind when maintaining bronze is that oxidation is a naturally occurring process for the material when it is exposed to air. Therefore, unless you intend to keep it locked up in a glass case, you can be certain that it will develop patina again after cleaning. The other thing you can do to protect the material is to coat it in entirely with lacquer. Make sure not to miss a spot.

Types of Bronze Alloys

As was mentioned earlier, there are different types of bronze metals, depending on what combination is used. While each type would have their own special attributes, what remains constant across the board is the strength and durability, which is why it’s considered to be one of the most reliable metals around.

Aluminum Bronze

– This is said to be the strongest among all types of bronze. It also scores major points for being corrosive-resistant. It has a more industrial functionality too, precisely because of these features. It’s most commonly used in marine hardware as well as in pumps that carry corrosive materials.

Copper Nickel

– Like aluminum bronze, copper nickel is also strong and corrosive-resistant. What makes it stand out, however, is its strong thermal stability. This makes it ideal for the manufacturing of ship hulls, other marine equipment, electronic components, and the likes.

Nickel Brass

– This type of bronze takes on a more silvery color because of the nickel, although the copper content does retain the trademark bronze strength and resistance to corrosion. Common uses of nickel brass include food and beverage equipment, optical equipment, and musical instruments.

Phosphor Bronze

– Otherwise known as tin bronze, phosphor bronze is known for being highly durable and fatigue-resistant. It also has coefficient of friction. Because of its features resulting from its composition, this type of bronze is most commonly used in the manufacturing of electronic components, washers, and others.

Silicon Bronze

– Comprised of copper and silicon, this type of metal otherwise known as “red silicon bronze” actually only has as much as 6% silicon. Zinc actually comprises 20% while the rest is copper. Pumps and valve parts are the usual products to come out of this particular metal type.

Bronze in Design

Knowing the different types of bronze is crucial in determining what to incorporate in your designs. Especially if you would like to make something more custom, choosing the right materials would be very helpful for your cause.

Establishing a design theme or aesthetic is a good way to start. Identify how big a component is bronze going to be in the overall look of your design. This way, you can plan early on which likely places you can incorporate it to. More importantly, you can easily get in touch with aluminium bronze suppliers and the likes so you can order the things you need immediately.

Having a well-stocked supply should help you move along with your project a lot faster and smoothly. Of course, that goes without saying that you should be mindful of your inventory so that you don’t end up wasting your resources.

Overall, having bronze elements in your design can work wonders in elevating an otherwise simple look into something a lot more elegant and stylish. Bronze frames, for example, can make pictures or paintings stand out even more. Little bronze trinkets and other crafts can help upgrade a simple wooden table. Bronze trimmings and linings can give that subtle shine to handrails, banisters, and interior sidings.

Of course, light fixtures, coat racks, even tables and chairs, cabinets and other decorative elements all could use a pop of bronze too to upgrade its looks. Incorporating these style elements would require a special kind of care, however, that’s why knowing how to care for and maintain these metals is equally important.

Metal suppliers such as Rotax Metals can help you find the right material that you need. With quality materials, you can better execute your design plans.

Some Facts Builders, Machinists, and Artisans Should Know before Buying Bronze Bars for Sale

bronze bars for saleAmong today’s countless types of commercially available metal, only a handful stand out due to their distinct, valuable properties. One that has stood the test of time and has been utilized for a vast array of applications for many generations is bronze. This metal has been around for over 9000 years, making it the first manmade alloy.

What Most People Know So Far

If you paid attention to your history teacher, chances are you already know a thing or two about bronze. You probably know the role it played in the world’s transition from the Stone Age to the Metal Age, and how it helped revolutionize metallurgy, technology, and even war. A great deal of artifacts made of bronze have been unearthed from ruins around the world, proving how valued this metal was in the ancient time.

Bronze became so popular that it was named after an entire era. As to why it became so popular, there are a couple of plausible reasons. First, the Metal Age was just at its early stage when bronze was discovered and the ancient people knew only of a few metals—gold, silver, copper, tin, iron, and lead—most of which didn’t have many utilitarian uses.

Second, of the first few metals available at the time, tin had the highest metallic bonding property, and it bound perfectly with copper but not with the rest of the available metals, which is why bronze was the only alloy they could produce. It would take a few more centuries before man could accidentally discover zinc-rich copper, which would later be polished into brass.

Over the years of working with bronze, metallurgists have not just perfected its composition and succeeded eliminating all its impurities but also created many variants with unique and useful properties of their own. Then again, all of today’s bronzes share certain distinctive traits, such as ductility, low-friction quality, and high machinability.

What Most People Should Know

There’s no denying the expediency of bronze for many industrial and commercial applications. If you need a material that exhibits high weldability, ease of brazing and soldering, and low thermal expansion coefficient, then bronze bars for sale and other bronze-based supplies are your best option.

However, it is also imperative to know bronze’s limitations so that you can make the most of its potentials. Here are some of the things you should anticipate and prepare for when using any bronze material.

  • Naturally Durable but Needs Extra Care to Last Even Longer.

    As previously mentioned, bronze is an extremely durable material. With the right combination of copper and tin, along with additional elements if any, and proper upkeep, you can produce a type of bronze that can last for thousands of years. Conversely, bronze is not an invincible material. Like most other metals, it has its own kryptonite. When you are working with bronze, make sure to keep any products containing ammonia and ferric compounds, sulfur, chlorine, and cyanides at bay as these substances can corrode the metal very quickly. The acids in bird droppings have similar effect as well so make sure to keep raw bronze in a covered place.

  • Unremoved Core May Migrate to the Surface

    Bronze casting usually involves a mold with a core made of gypsum. Depending on the desired finished product, the gypsum core may be left inside the bronze. Overtime, the gypsum may start to migrate towards the surface, weakening bronze in the process. As much as possible, when you are casting bronze, remove as many foreign materials from the interior and exterior surface of the finished product as possible. Other techniques on how to make bronze may not involve the use of gypsum so this won’t be a problem.

  • It Gets Ill, Too

    Non-living things don’t normally get sick. It turns out, such rule does not apply to certain materials, particularly bronze. When placed in an environment where chlorine and oxygen are present, this metal may develop a condition, called Bronze Disease. This disease is caused by the hydrochloric acid that forms when oxygen and chlorine combine in a moist setting. Therefore, it is crucial to avoid using chlorine when bleaching bronze items.

  • Why It Makes a Perfect Sculpture Material

    Builders don’t recommend bronze for structural applications, and for one good reason—it is softer than steel and other more common metals. While softness is usually viewed as a weakness when it comes to metals, there are ways to put it to good use. Bronze’s softness allows it to be chiseled and cut with ease, which is why it is the perfect metal for sculpture.

  • You May Need to Spend a Little More

    Bronze is not as common as it is popular, and the materials used to manufacture it don’t come cheap. Specifically, its copper content is what makes it expensive. Containing around 95 percent copper, bronze is almost as expensive as copper itself. If you are looking to use bronze for your projects, you will have to fork out a little bit more to afford it.

    Knowing these facts about copper can help you make an informed buying decision. More importantly, you’ll realize that you need advice from a metal expert to obtain the specific type of bronze material you need for your project. You can find one in a reputable metal supplier like Rotax Metals. It pays to invest in high-quality products, and so you better purchase from the right supplier.
