Product description

Beryllium Copper Strips 0.25 mm / 250 micron

Beryllium Copper Strips : Alloy 25 is also known as CuBe2, C17200, BeCu, CDA 172, CB101, ISO CuBe2, CEN CW101C, A4/2, beryllium bronze.

Size in mm: 0.25 x 200 x 200 mm mm (thickness x width x length)

Size in Inch : 0.0098 x 8 x 8″ (thickness x width x length)

250 micron = 0.25 mm = 0.025 cms = 0.0098 inch (thickness)

This alloy which contains approximately 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.
