What Properties Make Copper the Best and Where to Get Copper Rod and Other Supplies

copper in machines

If there’s one metal that has stood the test of time and has played a crucial role in the creation of the modern world, it has to be copper. Not only is it the first metal discovered and utilized, but even as new metals are being introduced on the industrial market every five years or so, it remained a highly relevant material, and for good reasons.

Apart from possessing a number of extremely valuable properties, copper is also recyclable. Even if copper mining stops at some point in the future, there’s enough scrap copper to resupply the market with and the cycle will continue. Unfortunately, not very many people are familiar with copper. If you ask a random person on the street to name a metal they’re familiar with, they’d probably say steel or aluminum, and there’s a good explanation to that.

Unlike steel and aluminum, which are commonly used for building visible structures like bridges and vehicles, copper is often found inside devices and machines, making it less familiar. There’s also the fact that copper is frequently used in its alloy form, which is typically far from its original appearance. Regardless, it doesn’t change the fact that copper is an amazing metal.

Applications

To get a feel for how amazing copper really is, let’s examine its applications based on its properties and form. Especially if you are planning to start a metal supply and distribution business or your project involves the use of copper, it pays to know what this metal can do and where it is utilized for. Reputable copper and brass suppliers like Rotax Metals can give you insights that can help you make the right choices.

According to Properties

Copper’s enduring relevance is predicated by its multitudes of levered properties. Here are some of the prominent ones and their applications.

Natural Elegance

Copper has a reddish-brown color, which changes into different shades of gold or tan when combined with other metals. The resulting alloys are perfect for cutlery, sculpture, architecture, and even jewelry.

Anti-Biofouling

Barnacles, weeds, and other saltwater lifeforms cannot attach on the surface of copper or its alloys, which is why it is used for ship hulls, hydraulic systems, and offshore oil and gas platforms.

Corrosion Resistance

Unlike steel and other ferrous metals, copper does not rust. Combining it with other non-ferrous metals makes it even more corrosion-resistant. Copper makes a great material for plumbing tubes and fittings, roofing, and distillation systems.

Electrical Conductivity

Copper is extremely conductive. It’s no wonder most communication, electrical transmission and distribution, resistance welding systems are made of copper.

Ductility

Copper and its alloys are easy to work, too, but they can preserve their mechanical strength. This property is perfect for general engineering, marine, defense, and aerospace applications.

Heat Capacity

Thanks to copper’s high heat capacity, it makes up most of cryogenic, liquid gas handling, heat exchange, and combustion systems. This metal can maintain form and strength even when exposed to high temperatures for a long period of time.

Antibacterial

There’s a reason why the doorknobs and railings in buildings are typically made of copper or its alloys. Copper has a natural antimicrobial property. Its molecules produce ions that can harm certain proteins in microorganisms, leading to their demise.

According to Form

Copper and its alloys can be manufactured into virtually anything, thanks to their high malleability and machinability. However, non-customized or mass produced raw copper supplies usually come in the following shapes and forms.

  • Sheet

    – Copper sheets are great for covering surfaces to add protection and aesthetic value. You can purchase a copper sheet from a local copper sheet supplier and use it on your kitchen countertop or backsplash to take advantage not just of its natural elegance but more importantly of its antimicrobial property.

  • Plate

    – If you want something thicker, try a copper plate instead, although it’s more commonly used for engraving purposes. Copper plates are great for device and machine casing, too. Pure copper, however, isn’t suitable for any application requiring metal plating as it forms patina after long exposure to air and moisture.

  • Tube

    –Copper is also a favorite material when making tubes and pipes. Not only is it extremely malleable, but it’s also antimicrobial, as previously discussed. Most copper tubes go to water filtration and distillation systems, food containment systems, and other structures with prohibitive sanitation requirements.

  • Bar and Rod

    – Typically produced through extrusion and tensile tested, copper bars and rods are later manufactured into auto parts, medical or electrical accessories, and other precision machine components. Whether you need a copper square rod, a copper round rod, or a copper bar for your project, large suppliers like Rotax Metals have you covered.

Copper is, without a doubt, a super-metal. Even with today’s technology, there are still aspects of this metal that we haven’t fully explored, and exploited for that matter. We expect to discover more new copper-based alloys in the coming decades and it’s going to benefit a vast array of industries.

Top Questions to Ask Copper Material Suppliers When Looking for the Perfect Plumbing Material

So you’ve started looking for a new home and there’s this lovely unit that you’ve been eyeing since day one of your search. When you checked it out, everything seems fine except for the plumbing, which looks old and needs some serious overhaul. You’ve decided to buy the house anyway and just have the whole plumbing system replaced.

It may seem easy but plumbing renovation is one complicated job. Even if you will hire someone to do it, there are still a couple of things you need to do. For instance, you should know what materials are necessary for the project. The last thing you want is spending top dollar for a material that won’t hold up for long. Here are guide questions you can use to find the perfect material for your new plumbing system.

Has anyone used the material before?

If a certain metal is not that popular even to suppliers, chances are it’s not the ideal choice. Go for a material that has been used by trusted builders in your area or the one used in well-built homes in your neighborhood.

Does it rust or corrode?

This is perhaps the most important question you should ask yourself and the supplier. You wouldn’t want to use a metal that will only contaminate your water with rust debris down the road. Choose a metal like copper or any of its alloys because they are proven capable of resisting corrosion. There are select copper material suppliers offering copper plumbing pipes that you can ask about the corrosion of metals.

Is it tough and strong?

Not all corrosion-resistant metals are ideal for plumbing construction. You also have to factor in the forces the material has to deal with. Water may be still when they are in a container but within pipes they flow at tremendous rate, creating immense pressure. Your material must be tough enough to resist puncture and strong enough to hold up to pressure and not burst.

Does it kill bacteria?

Not very many metals are capable of the oligodynamic effect, a phenomenon characterized by the release of certain ions, which destroy a particular type of protein in bacteria cells, eventually killing them. Metals like copper and silver are among the few that can, and should be on your list.

Who is selling it?

It is crucial that you also know who your supplier is. There are thousands of copper material suppliers in North America and probably hundreds within your area alone, so choosing can be quite tricky. But if you know what to look for, it can be easier. The supplier, first and foremost, must be an established business with a clean and impressive reputation. This means they must have been in operation for many years or even decades. It would also be wise to choose a company that specializes in copper, since it’s the material you will eventually need. After all, the answers to your questions will all boil down to choosing copper.

Asking the right questions is critical in purchasing any product, especially materials for your plumbing. Being able to pick the right material means you can build a sturdy and durable plumbing system for your new home. This also means you won’t have to worry about repair and maintenance for many years.

A Quick Guide to Etching Copper Sheets for Crafts

There are a number of ways to decorate metal. You can paint it, stick adornments on it, or even carve through its surface. After all, metals are malleable and very easy to work. They make a great material for a variety of crafts. Copper, in particular, is one of the most extensively used metals for making art pieces, thanks to its extreme workability. And one of the best ways to decorate copper is through etching. Here’s a guide for those who want to try etching copper sheets for crafts.

etching copper sheets

Step 1: Preparation and Safety

Etching involves the use of acid or mordant, usually ferric chloride. Either chemical can burn your skin. It’s important to observe basic safety precaution to avoid possible injury. Wear safety glasses and gloves to protect your body from spillage. Before you wear them, make sure to prepare the copper sheet you will be etching first. Clean and dry it thoroughly to remove any residue that might inhibit the etching process.

Step 2: Design and Resist

Now that you have the blank copper sheet set, the next step is to choose a design and put it in a resist either through cutting or printing. A resist is a substance that covers the areas on the metal that you don’t want to be etched. It can be anything from photocopy ink to photo film. Make sure to line the resist up properly to produce a fine output. If you are using ink as your resist, make sure it is completely dry before applying the acid to prevent it from smudging. Cover the back of the plate with resist, too, so it won’t react with the solution.

Step 3: Tape and Etch

To further protect the areas on the blank surrounding the design, you have to cover them with tape. Cover even the back until there’s no air gap left. A burnisher can help push the tape flat down so all gaps are eliminated. Once you’re done, slowly lower the blank into the etching solution and leave it there for at least half an hour. Every 5 to 10 minutes, stir the solution with the blank to shake off residue and improve the etching process.

Step 4: Neutralization

Once you confirm that all sections of the design have been properly etched, prepare another solution. This time, it’s a solution meant to neutralize the acid on the plate so you can safely hold it and apply the finishing. The neutralizing solution is simply a mixture of baking soda and water. Baking soda is known to have the ability to defuse the coarseness of acids.

Step 5: Cleaning and Finishing

Once you’ve removed the tape and the resist from the blank, you’ll notice slight discoloration on the surface of the blank. Don’t panic. This is normal. All you have to do is to clean and polish the surface of the etched copper thoroughly to get rid of most of the stain and bring out the sheen hiding beneath it.

To get the best results, make sure your copper blank is made by a trusted foundry and is supplied by a reputable supplier like Rotax Metals. You don’t have to go far just to find out where to buy copper sheets because Rotax Metals is a prominent brand. Experts like them can teach you the right etching techniques as well.
