Copper alloy disk

Copper alloy discs are precision circular material products made from copper as the base material, formed by adding different alloying elements. This material combines the advantages of pure and alloy gold.  This product integrates the superior electrical and thermal conductivity of pure copper with the reinforcing characteristics provided by specific alloying agents.The material includes different alloys such as phosphor copper, beryllium copper, tungsten copper, zirconium copper and silver copper. Customers can choose the most suitable products and accessories according to their specific needs.

Our Copper Alloy Disks are used in multiple industries.

• In the aerospace and defense sector, high-strength beryllium copper disks are used for precision aerospace components and navigation instruments: precision instrument bearing housings, gyroscope assemblies.
• In the oil and drilling industry, Copper Alloy Disks are used to manufacture components for non-magnetic stabilizers, explosion-proof tool gaskets, and downhole instrument pressure plates.
• In marine engineering, Copper Alloy Disks are used for seawater-resistant valve seats, flange covers, and pump body sealing rings.

Our Copper Alloy Disks offer multiple functions and advantages:

1. Heat dissipation and conductivity: Serving as a core current transmission or heat dissipation carrier in electrical equipment.
2. Insulation and stress relief: Our copper discs act as protective washers on rotating mechanical components, protecting spindle components from corrosion.
3. Explosion Protection: In flammable and combustible gas environments, our copper discs do not emit heat during combustion, which increases their efficiency.
4. Magnetic shielding: For applications that require protection against magnetic fields, such as road drilling, our copper discs offer mechanical stability.

We have excellent manufacturing processes, using methods such as hot forging, die forging, cold rolling, heat treatment and surface treatment to bring our products to the condition required for our customers. High-temperature forging can break down cast grains, making the internal structure of the disks denser and eliminating porosity; cold working can be done to increase hardness according to thickness requirements, or high-precision sawing can be used to cut discs; annealing, solution treatment, or aging treatments may be performed to achieve specified hardness requirements; pickling, polishing, silver plating or nickel plating are optional to increase conductivity or oxidation resistance.

We adhere to standards such as GB/T 4423, ASTM B150, ASTM B196, and DIN 17660, and can perform mechanical property tests such as tensile testing and hardness testing to determine tensile strength, yield strength, elongation, and Brinell hardness; we can also perform physical property tests such as thermal expansion and thermal conductivity, and non-destructive testing such as ultrasonic testing and penetrant testing to detect internal defects, delamination, and porosity in products. We can process customer-specified dimensions according to drawings and can also provide customized tolerances.
