Application of Copper Sheet

Copper can be manufactured into different forms but it’s most popular in sheet form. After all, there are tons of applications that require copper sheets. Regardless of the copper sheet thickness, there will always be a use for it. This metal product is so popular you have trouble identifying where to buy copper sheets whenever you find the need. Here are some of applications of copper sheet metal.

Welding fixtures

Before welding product parts, their geometry must be secured using welding fixtures to ensure the quality of the final product. Copper alloys are ideal for such application. In case you are building your own welding setup and asking “how thick should my copper sheet be?” there are guides online that you can follow.

Ground straps

Any system or machine that runs on electricity must have a ground strap to protect essential components and people from electrostatic discharge (ESD).

Plumbing fitting

Copper, being resistant to corrosion, is an ideal material for flashing. It’s even perfect for roofing but, since copper is expensive, many people don’t find it practical.

Power transmission

Most sprockets, sheaves, belt pulleys, and bushings used in power transmission systems are made of durable and wear-resistant metals. Many alloys of copper fit the criteria.

Heat exchanger

The majority of components of heat exchangers are made of copper or its alloys, thanks to copper’s high heat capacity.

Properties of Copper

Our dependence on copper for many of our daily necessities comes from its many properties, which allow it to be turned into materials that are valuable in manufacturing basic commodities and utilities. There are many other metals that have similar properties but they are either not as stable or far less abundant. Let’s take a look at some of the properties that make copper a great metal.

Malleability
Copper can be hammered or rolled into thin sheets or plates without breaking. In fact, there’s a vast range of thicknesses copper can be manufactured into that distributors have made an entire copper sheet thickness chart. Each option can be used for highly specific functions from machine plating to surface embellishment.

Ductility
Copper can be drawn into small wires as well. Most of the electrical cables used in buildings have a copper core. Unlike other metals that become breakable in strips, copper remains hard even when it’s drawn into strands of very small diameters.

Corrosion Resistance
Many artifacts that date back several thousands of years are made of copper, which gives us a clue how long this metal can last. Copper, surely, corrodes just like any other metal. It’s just that the substances that can corrode it aren’t as common as those that corrode other metals.

Electrical Conductivity
It’s not just copper’s ductility that makes it a favorite material for making wire cores. Copper is also known to have superior electrical conductivity. It’s the second most highly conductive metal on the planet, next to silver.

High Heat Capacity
Copper can withstand very high temperatures, including heat produced by high voltages, which is also a reason why it’s the ideal material for making electrical wires. While silver has a higher electrical conductivity, it heats up very fast, causing fire hazards.

Antimicrobial Property
Most non-ferrous metals have the ability to release ions that damage certain proteins in microbes, killing them in the process. Copper, being the king of the non-ferrous, can decimate a great deal of bacteria in a short span of time, which is why it is ideal for making tubes and containers for water distribution and food processing.

Process of Copper Sheet

Copper extraction and refining

The manufacturing process of thin copper strips begins with the extraction of copper from the earth. Copper ore is mined and undergoes several refining processes to obtain pure copper. This includes crushing, grinding, and flotation, followed by smelting and electrolysis to achieve a high level of purity.

Copper casting and rolling

Once the pure copper is obtained, it is cast into large rectangular shapes called anodes. These anodesare then heated and rolled through a series of mills to gradually reduce their thickness and shape them into thin copper sheets. Rolling can be performed using hot or cold processes, depending on the desired properties of the final strips.

Annealing and pickling

To enhance the mechanical properties and remove any impurities, the rolled copper sheets undergo annealing. Annealing involves heating the copper to a specific temperature and then slowly cooling it. This process helps improve the flexibility and ductility of the copper, making it easier to work with in subsequent manufacturing steps. After annealing,the copper strips are pickled to remove any oxide layers or surface impurities.

Cold rolling and slitting

The next step in the manufacturing process is cold rolling, where the annealed copper strips are passed through multiple sets of rollers to further reduce their thickness. This cold rolling process can achieve the desired thinness and uniformity of the copper strips. Once the desired thickness is reached, the strips are slit into narrower widths using precision slitting machines, yielding thin copper strip of specific dimensions.

Surface treatment and quality control

After the slitting process, the thin copper strips may undergo surface treatments to enhance their performance or aesthetics. This can include processes such as electroplating, coating, or applying protective films. Additionally, quality control measures are implemented throughout the manufacturing process to ensure that the thin copper strips meet specific standards and requirements. Testing and inspection are conducted to verify the mechanical, electrical, and dimensional properties of the strips.

Components of Copper Sheet

The copper most commonly used for sheet and strip applications complies with ASTM B370. It consists of 99.9 percent copper, and is available in six tempers designated by ASTM B370 as: 060 (soft), H00 (cold rolled), H01 (cold rolled, high yield), H02 (half hard), H03 (three quarter hard), and H04 (hard).

How to Maintain Copper Sheet?

A vinegar (also known as acetic acid) and salt mixture is a simple but effective method to clean copper. It’s free of harsh chemicals and an affordable option. One tablespoon of salt to one cup of vinegar can be used as a ratio for the mixture. Using a soft cloth or soft scrubbing pads, rub the mixture on the copper followed by a rinse of water and a pat dry. Do not use steel wool as it is a harder metal than copper and will damage it. Allowing the copper to soak in the vinegar and salt solution is optimal but not always an option when dealing with copper sheet metal.

Citric acid, available in powder form, can be used as a diluted solution. In place of powdered citric acid, lemon or lime juice is a great substitute. Two and a half teaspoons of citric acid to one cup of water can be used as a ratio. Similar to the vinegar and salt mixture, use a soft cloth or scrubbing pad to apply the mixture. Avoid exposure to direct sunlight or other acids immediately following using a citric acid-based cleaning solution.

Another option is acetone. Acetone is a solvent that can be used with a soft cloth to remove stains from copper. Just make sure your workspace is well ventilated. You also better work fast because the acetone will evaporate very quickly.

Although some sources will recommend the use of ammonia, it should be avoided. Ammonia is a harsh chemical, and even as a diluted solution, it can cause the copper to become brittle and crack. In addition, this cleaning method leads to the copper being difficult to solder.
