Beryllium copper, also known as copper beryllium, BeCu or beryllium bronze, is a metal alloy of copper and 0.5 to 3% beryllium, and sometimes with other alloying elements. There are a few alloys of Beryllium Copper but the most commonly used is “ALLOY 25” which available with us in ready stock.     ALLOY 25 Alloy 25 is also known as “CuBe2, C17200, BeCu, CDA 172, CB101, ISO CuBe2, CEN CW101C, A4/2, beryllium bronze”. This alloy which contains approximatively 2% of beryllium and achieves the highest mechanical strength and hardness after heat treatment of all copper beryllium alloys. In soft or slightly re-rolled condition, it exhibits excellent bending behaviour. It distinguishes itself by high fatigue strength, outstanding relaxation resistance at elevated temperatures and a unique combination of high strength and excellent electrical conductivity.   Similarly, we also have CuCrZr [C18150], CuNiBe / CuNi2Be [C17510], CuCo2Be [C17500], etc   PROPERTIES High Conductivity Elevated Temperature Strength Reflectivity Dimensional Stability Highly Machinable High Tensile Upto 300 Ksi.
