Introduction:

Beryllium copper alloys are a family of alloys that exhibit unique properties such as high strength, ductility, and thermal conductivity. CuBe2 beryllium copper is one of the most widely used alloys in this family, thanks to its excellent mechanical and physical properties. In this article, we will discuss the properties and applications of CuBe2 beryllium copper.

What is CuBe2 Beryllium Copper?

CuBe2 beryllium copper is a copper-based alloy that contains 1.8-2.0% beryllium and a small amount of nickel. The addition of beryllium to copper improves its strength, hardness, and corrosion resistance. Nickel is added to improve the alloy’s ductility and toughness. CuBe2 beryllium copper is also known as C17200, UNS C17200, and RWMA Class 4.
