Import Chromium Zirconium Copper — Buy in Bulk from Supplier in China

ALB Copper Alloys Co., Ltd. supplies Chromium Zirconium Copper (CuCr1Zr, UNS C18150), a precipitation-hardened copper alloy containing approximately 0.6% chromium and 0.1% zirconium. The alloy achieves a tensile strength of 550-650 MPa and electrical conductivity of 80-85% IACS after thermal treatment, as indicated in the product description. It is produced using vacuum melting and controlled cooling to ensure homogeneity.

The alloy's strength derives from fine CrZr precipitates that form during aging, while the copper matrix maintains high thermal and electrical performance. It is not suitable for cold working beyond 15% reduction without intermediate annealing. Typical forms include rod, bar, and wire, with standard diameters from 3 mm to 50 mm. Surface finish is usually mill finish unless otherwise specified. The material is not plated or coated unless requested.

This alloy is used in high-wear electrical contacts, resistance welding electrodes, and busbars in aerospace and automotive applications. Buyers include manufacturers of high-current switchgear, EV charging components, and precision instruments. Orders are typically placed in 500 kg lots, with packaging in wooden crates or steel coils. Trade terms are FOB Xiamen, and lead time is 4 to 6 weeks after order confirmation. Buyers should confirm dimensional tolerances and heat treatment certification before procurement.

ALB Copper Alloys Co., Ltd. is registered with an address in Xiamen, Fujian Province, China, indicating a manufacturing or processing facility in a known copper alloy production region. The company is categorized as 'imported' and 'harbor' trust tier, suggesting verified business registration and export activity. No claims are made about years in operation, workforce size, production volume, or client names. The listing does not reference certifications, quality audits, or in-house testing labs.

The company appears focused on copper-based alloys, with this product being the only one listed. There is no public information on metallurgical capabilities, heat treatment facilities, or material traceability systems. Response rate and average response time are not recorded, indicating limited buyer interaction on the platform. Buyers should request material test reports and chemical analysis certificates directly from the supplier before placing bulk orders.
