It is highly superior among alloys and is suitable for applications that handle heat and electricity, such as resistance welding electrodes!
"Chromium copper" is a high-copper alloy that is precipitation-hardened by adding approximately 0.4 to 1.2% chromium to copper. It is characterized by high electrical conductivity, thermal conductivity, heat resistance, and corrosion resistance, along with excellent wear resistance and hardness. These properties make it widely used in applications such as backing plates for semiconductors, backing metal for bearings in gas turbines and steam turbines, and various resistance welding electrodes. Our company is capable of processing chromium copper. You can trust us with small lots, custom matching, short delivery times, large-scale processing, and ultra-precision machining. [Main Features] ■ High electrical and thermal conductivity: Extremely excellent among alloys, suitable for applications handling heat and electricity, such as resistance welding electrodes. ■ High heat resistance and wear resistance: Minimal reduction in hardness and tensile strength even in high-temperature environments, capable of withstanding long-term use. ■ High corrosion resistance and hardness: Resistant to rust, and the alloy is hard enough to produce hard chips during processing. ■ Precipitation-hardened alloy: Hardness and strength can be adjusted and improved through heat treatment (quenching and tempering). *For more details, please download the PDF or feel free to contact us.
