Import Cucrzr C18500 Copper Alloy Strip — Buy in Bulk from Supplier in China

CuCrZr C18500 is a precipitation-hardened copper alloy containing approximately 0.1% to 0.3% chromium and 0.05% to 0.15% zirconium, with copper as the base. This combination enhances recrystallization resistance and strength while maintaining high electrical conductivity, typically above 85% IACS. The material is supplied as cold-rolled strip in thicknesses ranging from 0.1 mm to 3.0 mm, with widths up to 600 mm.

The alloy is not pure copper; the addition of chromium and zirconium forms fine intermetallic precipitates during aging that stabilize the grain structure. This prevents softening during high-temperature operations, making it suitable for resistance welding electrodes and busbars in high-frequency environments. Surface finish is typically bright or mill finish, with no plating or coating applied. It conforms to ASTM B601 and EN 12164 standards.

Buyers include manufacturers of power electronics, automotive connectors, and aerospace terminals where thermal stability and electrical performance are critical. The material is also used in induction heating coils and high-current bus systems. Trade terms are typically FOB Qingdao or CIF, with packaging in moisture-sealed cardboard or wooden crates. Minimum order quantities are not specified and must be confirmed directly with the supplier.

Taian Henson Metal Co., Ltd. is a registered metal supplier based in Taian, Shandong Province, China. The supplier is classified as imported tier with harbor trust verification, indicating it handles export documentation and logistics. No factory address, production capacity, or workforce size is disclosed in the listing. There is no mention of in-house rolling mills or heat treatment facilities.

The company does not claim to manufacture the alloy from ingot but sources and distributes CuCrZr C18500 strip. It provides no details on quality control protocols, lab certifications, or testing equipment. Response metrics are not available. Buyers should assume this is a trading company that sources material from third-party mills and repackages for export, not a primary producer.
