Chromium-Zirconium-Copper Plate: High-conductivity, High-temperature Resistant, And Wear-resistant Copper Plate for Industrial Applications.

Product Description

Chromium-zirconium-copper plate is a high-performance copper alloy product manufactured from a high-purity oxygen-free copper base, precisely alloyed with trace amounts of chromium and zirconium. It is produced through a series of advanced processes, including smelting and forging, age hardening, precision rolling, and fine grinding and polishing. Common grades include C18150, C18400, and CW106C; it is a specialized industrial copper material characterized by high strength, superior electrical and thermal conductivity, and excellent resistance to heat and wear. Unlike standard pure copper or brass plates, this material utilizes grain-refining alloy technology to achieve an optimal balance between electrical conductivity and mechanical properties, effectively overcoming the limitations of pure copper (such as low hardness, susceptibility to deformation, and poor high-temperature resistance) and the conductivity deficiencies of conventional copper alloys. The plates feature a flat, smooth surface free from porosity, pinholes, or oxidation spots, with a dense and uniform microstructure. Thanks to professional aging treatment, the material offers stable performance and is capable of withstanding demanding industrial conditions—such as high currents, elevated temperatures, high-frequency friction, and heavy mechanical loads—making it a key material for sectors including resistance welding, electrical power, precision machinery, and high-end electronics.
