Copper Grade Applications
Able to be cold or hot worked, copper is a versatile metal across a wide range of industries and applications:
- Automotive: Copper tubing is an essential component of many of today’s automotive components, specifically copper-nickel brake tubing, heat exchangers, and radiators.
- Electrical: Because of its excellent conductivity, copper is an ideal material for a wide range of electrical applications, enhancing energy efficiency and power quality. Copper is commonly used in wires, windings, cables, transformers, electric motors, printed circuit boards, electromagnets, heat sinks, and busbars.
- Fuel Gas: Copper tubes are excellent materials for natural gas piping systems.
- Marine: Copper’s corrosion resistance, biofouling resistance, and strength make it perfect for a wide range of marine applications.
- Machining: Copper alloy rods and bars are ideal for machined products.
- Telecommunications: Modern telecommunications systems rely on copper wiring as a low-cost, high-performance solution.
- Industrial heat exchangers – Provides thermal conductivity, strength and corrosion protection
- Musical Instruments: Horns, trumpets, trombones and saxophones
Common Uses for Copper
Copper alloys have a long history of use because copper is easy to machine and turn into various forms. Copper is an excellent conductor of heat and electricity, resistant to corrosion, and naturally antimicrobial. These properties make the metal ideal for:
- Electrical wiring: Copper is an excellent conductor of electricity and is often used in electrical wiring.
- Roofing: Copper is a popular roofing material due to its durability and weather resistance.
- Pipes and plumbing: Copper is commonly used for pipes and plumbing due to its corrosion resistance and antibacterial properties.
- Cookware: Copper cookware is popular because the material effectively conducts heat.
- Decorative items: Because of its aesthetic appeal, copper is often used for decorative items such as sculptures and jewelry.
- Electrical components: Copper is often used in electrical components such as resistors, capacitors, and heat exchangers.
