Product Description

Beryllium Copper C17200 CuBe2 Resistance Seam Welding Electrode Rod

Description

C17200 Copper beryllium alloys have high strength and good thermal and electrical conductivities. High conductivity alloys and high strength alloys are the two major types of copper-beryllium alloys. The high conductivity alloys have 0.2-0.7% of beryllium and high cobalt and nickel contents. The wrought high-strength alloys consist of 1.6 to 2.0% of beryllium and nearly 0.3% of cobalt and the cast high-strength alloys contain up to 2.7% of beryllium. The wrought alloys are named as C17200 to C17400, and the cast alloys are designated as C82000 to C82800. C17200 alloys have a high tensile strength of over 1380 MPa (200 ksi).
