The most popular alloy in the copper beryllium family is UNS C17200 and is commonly known as beryllium copper Alloy 25. In Europe, this alloy is referred to as CuBe2. It has 1.8 – 2% Beryllium and is the hardest and strongest copper beryllium material widely used. Applications include injection mold tooling cores and cavities, oil and gas drilling tool components, aerospace bushings, and heavy equipment wear plates and bushings. The terms “beryllium copper” and “copper beryllium” or even beryllium bronze are used interchangeably. Also, CuBe and BeCu are abbreviations that are frequently written. C17200 (Alloy 25) is a high performance alloy and so it is important to have confidence in your supplier
C17200 Beryllium Copper is manufactured to provide a combination of high strength and hardness properties coupled with superior thermal properties. This range of properties makes C17200 Beryllium Copper the premier material for copper alloy molds and a wide range of other applications from oil and gas to aerospace.
Beryllium Copper plate products have very low impurity levels, are fully dense and structurally sound with excellent machining and fabrication properties and a consistent, homogeneous fine grained micro-structure.
