C18150 CrZrCu Copper Alloy: Properties and Applications Explained

C18150 Chromium-zirconium copper is a highly attractive high-strength and high-conductivity copper alloy. Due to its excellent comprehensive physical and mechanical properties such as electrical and thermal conductivity, corrosion resistance, and solderability, it is widely used in industrial fields such as power, electronics, machinery, automation, and metallurgy. It is a key focus that major industrial countries around the world are competing to research and develop to support the development of large-scale integrated circuits. With the rapid development of the electronics industry and high-speed trains, higher requirements have been put forward for copper alloy materials in terms of their application. Chromium-zirconium copper alloys have thus entered a period of high glory.

C18150 Chromium-zirconium copper is a copper alloy material composed of metal elements such as chromium, zirconium and copper. The chemical composition of chromium-zirconium copper (CuCrZr) is: (mass fraction) % (Cr:0.1-0.8,Zr:0.3-0.6), hardness (HRB78-83), electrical conductivity 43ms/m (≥80%IACS), softening temperature 550℃. Due to its excellent electrical conductivity, thermal conductivity, high hardness, high strength, wear resistance, explosion resistance, crack resistance, and high-temperature and high-pressure resistance, C18150 CuCrZr copper is widely used in motor commutators, electrodes for spot welders, seam welders, and butt welders, as well as other parts that require strength, hardness, and electrical conductivity in high-temperature environments. It is easy to weld and features low electrode loss during welding and fast welding speed. The advantage of low total welding cost.

Application features of  C18150 CuCrZr alloy: Excellent comprehensive performance is obtained through cold working and precipitation strengthening treatment. CuCrZr has excellent electrical and thermal conductivity, medium strength, and outstanding resistance to stress relaxation and high-temperature softening.
