Import Cube2--Uns.C17200 Beryllium Copper Alloys — Buy in Bulk from Supplier in China

CuBe2 alloy, designated as UNS C17200 and CDA 172, is a high-performance copper beryllium grade supplied by Alb (xiamen) Material Company Limited in forms including round bars, strips, wires, tubes, plates, sheets, and coils. The alloy contains 1.85 to 2.10 percent beryllium, with cobalt and nickel at minimum 0.20 percent and maximum 0.60 percent combined with iron, while copper forms the balance to achieve a minimum 99.5 percent purity. In its fully aged condition, it delivers ultimate tensile strength exceeding 200 ksi and hardness approaching Rockwell C45, alongside electrical conductivity of at least 22 percent IACS.

This alloy is noted for its exceptional resistance to stress relaxation at elevated temperatures, making it suitable for high-load applications in aerospace, automotive, and electronics. Standard forms comply with international specifications such as ASTM B196, B194, and B197 for rods, strips, and wires respectively, with European standards referencing CuBe2, DIN 2.1247, and CW101C to EN. Typical physical properties include a density of 8.36 g/cm3 after age hardening, an elastic modulus of 13.40 x 10^3 kg/mm2, and a melting range of 870 to 980 degrees Celsius.

Importers source this material for connectors, springs, and switches in industries where durability and conductivity are critical. Alb (xiamen) Material Company Limited offers custom diameters, sizes, and mill lengths, with shapes available upon request. Buyers should confirm the form, size, and heat treatment condition to match their application, as dimensions and tolerances are tailored to specific use cases.

Alb (xiamen) Material Company Limited is based in Xiamen, Fujian Province, China, with its office located at Rm801-803, Zian Pavilion, No.186 Huarong Road, Huli District. The company operates as an imported-tier supplier, specialising in high-performance copper alloys, including beryllium copper grades like CuBe2.

The supplier’s profile indicates a focus on custom sizing and forms, with random mill lengths available and custom shapes offered upon request. While the listing does not provide details on response rates or verification signals, the company positions itself as a source for precision-engineered materials tailored to industrial applications.
