Malleability, the Property that Makes Bronze Sheet Metal Manufacturing a Breeze

Every metal has a certain degree of malleability, the ability to deform under compressive stress without breaking. This property is critical because it allows metals to be utilized for various applications, including surface protection, ornament, architectural design, and machine parts.

Bronze, A Perfect Marriage of Two Magnificent Metals—Copper and Tin

Some metals are more malleable than others. In fact, there are metals whose malleability is too negligible to be utilized. Among the many malleable metals out there, copper is arguably the most extensively used. This is because it can be easily alloyed with other metals to form even stronger and more durable materials.

Even after alloying, copper retains its malleability, making the new material pliable as well. Bronze is an example of alloy that inherits the malleability of copper. Although not as malleable as other prominent metals, such as gold, silver, and aluminium, bronze sure is very easy to work with, especially to be flattened into usable sheets of varying thicknesses.

Understanding the Malleability of Bronze

Bronze is not really the best example to use when explaining malleability, but it does go flat when hammered, pressed, or rolled. It can only tolerate so much pressure before finally breaking. In fact, regular bronzes have the tendency to become brittle when applied with an abrupt force.

Bronze’s malleability depends on the amount of copper and tin and the crystal structure of their molecules. Most bronzes have a little over 80 percent copper and 12 percent tin. The rest consists of additional elements in miniscule amounts, such as aluminium, manganese, nickel or zinc, which also affect bronze’s malleability.

If you look at bronze’s molecular structure through an electron microscope, you’ll notice that those bronzes that have almost symmetrical arrangement of copper and tin molecules are most tolerant to pressure. They neither deform nor break easily even if bronze is naturally brittle.

Plus, a good crystal structure also contributes to bronze’s ability to resist vibrations. The tin atom placed in a strategic spot within a uniformly arranged cluster of copper atoms in the composition prevents the atomic plain from slipping freely, keeping it in place regardless of the kind of force applied to it.

Quality Bronze from an Experienced Supplier

Of course, the perfect mix of copper and tin in bronze does not occur by chance. It is with the expert skill of metalworkers that a seamless crystal structure can be achieved. Unfortunately, not all suppliers have this kind of skill. It takes decades of experience in metallurgy to create bronzes of the most desirable compositions.

Saving and Preserving Bronze Sheets and Other Pieces Using Wax

Bronze sheets and similar pieces are metal alloys that are manufactured specifically to last for decades with minimal care and maintenance. For that reason, many collectors value high-quality outdoor bronze fittings and sculptures. The issue with bronze, however, is that it is still susceptible to weathering and tarnishing after years of constant exposure. As any collector should know, the key to preserving the beauty and value of bronze pieces is through proper cleaning and waxing.

Old and Tarnished Bronze Sheets Given New Life with Proper Waxing

Take note that proceeding with the waxing of bronze metal sheets without doing further research can do more harm than good. Here’s a quick guide all about the basics of bronze waxing:

Step 1: Correct Bronze Cleaning

Before attempting to wax bronze pieces, learning how to clean them is the first step. There are different ways to clean the surface, but the easiest, cheapest, and most effective is by using warm water with soap. Use the soapy water some gentle scrubbing and clean the pieces until the desired shine and appearance is achieved.

Step 2: Drying the Pieces

Before proceeding with this next step, be sure to thoroughly dry the bronze metal sheet or sculpture. Try patting down the pieces with a clean soft cloth to reach small cracks and crevices where water can gather. If water is left on the bronze fittings the wax will trap the liquid inside and this will cause a lot of damage.

Step 3: Proper Waxing Techniques

Choose a preferred brand of bronze wax. Read up on the list of chemicals that are corrosive to bronze and check the ingredients before purchasing. This will save you a lot of trouble and prevent damage. Next, get your thoroughly dried pieces, a clean cloth, or a brand new soft brush. Use the cloth or brush to apply a layer of wax, closely following the instructions provided by the wax manufacturer. Let the wax dry for about 30 minutes.

Step 4: Buffing and Reapplication (If Necessary)

After the wax has dried a soft cloth or a shoe brush can be used to buff the pieces until they shine and gleam. It is also suggested to reapply 2-5 coats of wax on outdoor bronze pieces for extra protection.

Step 5: Re-Waxing

Most bronze wax brands only need reapplication after a few months. Each brand will provide instructions on how the re-application process goes. Always read these instructions before re-waxing any bronze pieces.

A Bit of Elbow Grease Goes a Long Way

With the right care and enough effort, even really old and severely tarnished bronze metal sheets can regain their shine. This is something all collectors or even just homeowners who value their bronze fittings should learn to do for the sake of preservation.

Using Bronze Tube and Other Similar Metals for Jewelleries and Other Crafts

Creating jewelleries and other crafts can become more fun and challenging when you use special kinds of metal. These materials come in different forms, each of which exhibit a unique level of strength and versatility. When used properly, metals can yield the most beautiful results.

Bronze Tube and Pieces Are a Great Material for Making Jewelleries

For beginners, jewellery making can certainly be a daunting task. It takes extreme care and precision to ensure that the base metal, such as bronze tube and other similar items, won’t be put to waste. If you are just learning the ropes for working with these types of metals, particularly bronze, here are some tips that could help you improve your craft.

Why Use Bronze

One of the reasons why bronze is such a viable material for jewellery making is that it has high strength and low melting point. It is easy to shape into different forms and styles because it easily reacts to concentrated heat. Once it hardens, however, it’s difficult to deform or bend out of shape again. The trick, perhaps, is in the combination of the metals copper and tin in this particular alloy.
What sets it apart from other metals, however, is that bronze works very well for casting, primarily because it expands slightly before finally setting onto the form. This is why bronze sculptures, for example, make for such a magnificent view—the smoothness it achieves can also deliver an amazing impression of forms and visuals.

Bronze in Jewellery

Bronze used to be a lot more dominant in jewellery making in the olden times. Large, heavy accessories, such as elaborate necklaces and bracelets, dominated fashions of old. Nowadays, however, bronze material is better appreciated in wires or as flattened sheets, or even jump rings for chain maille. Bronze metal clay is also a huge hit for those who would like to have more texture and creativity in their use of the material.

Strong Metal, Strong Color

Don’t be too quick to dismiss bronze as a jewellery material because of its strong, earthen color. If anything else, this is precisely what you should be making the most out of, highlighting it in your jewellery crafts. Mix and match it with cooler shades and hues of color to bring out the contrast and texture of the material. Unless your goal is to come up with specially eye-catching and head-turning designs, you could do away with the brighter hues for stones and metals, like yellow or golden tones.

Incorporating Elements

It’s actually pretty easy to integrate bronze with other materials. A bronze tube, for example, can be crafted into a bracelet, which then could have another metal component to it, such as a silver outer lining, or another chunk of a bronze stone for height.

Cleaning Bronze Jewellery

Bronze is prone to developing patina upon exposure to oxidation. If you’re working on a bronze project for a long period of time, make sure to give it a good clean first as soon as you finish before putting it on display. Many DIY-ers swear by the lemon juice cleanse for bronze materials. It’s easy, cost-efficient, and definitely effective. With this, you can at least make sure that your final jewellery product is going to shine its best.
Before all of this, of course, you need to be able to find a trusted supplier that you can get quality metal materials from, such as Rotax Metals.
