Import Cucr1--Uns.C18200 Chromium Copper Alloys — Buy in Bulk from Supplier in China

CuCr1--UNS.C18200 is a precipitation-hardened copper-chromium alloy containing approximately 0.6% to 1.2% chromium by weight, with the balance being copper. This composition delivers a unique combination of high electrical conductivity, typically above 80% IACS, and tensile strength exceeding 500 MPa in the aged condition. The material is produced through controlled melting and hot working processes, followed by solution treatment and aging to achieve its mechanical properties.

The alloy is not plated or coated; its surface integrity relies on the base material’s inherent corrosion resistance. It is typically supplied in annealed or hardened tempers, with standard forms including bar, rod, and strip. In industry, it is commonly referenced under ASTM B601 and EN 12163 standards. The chromium content forms fine precipitates that enhance strength without significantly compromising conductivity, distinguishing it from pure copper or copper-zinc alloys.

This material is primarily purchased by manufacturers of electrical contacts, switchgear components, and aerospace connectors where both thermal dissipation and mechanical endurance are critical. Buyers in the automotive and rail industries also specify it for high-current busbars. Trade terms are typically FOB Xiamen or CIF port of destination, with packaging in wooden crates or steel strapping. Minimum order quantities are not stated in the listing and must be confirmed directly with the supplier.

Alb (xiamen) Material Company Limited is a registered importer and distributor based in Xiamen, Fujian Province, China. Its physical address is listed as Rm801-803, Zian Pavilion, No.186 Huarong Road, Huli District. The supplier profile indicates it is classified as an imported tier with harbor trust verification, suggesting it handles export logistics and documentation. There is no public information on manufacturing capacity, years in operation, or workforce size.

The company does not claim to produce the alloy itself but sources and supplies CuCr1--UNS.C18200 material to international buyers. It provides no details on internal quality control processes, lab certifications, or in-house testing equipment. Response metrics are unavailable, and no contact information beyond the address is provided. Buyers should treat this as a trading entity, not a mill or primary producer.
