Beryllium copper is a copper-based alloy material without tin, with beryllium as the main element. It is a type of copper alloy that is strengthened by age precipitation. It contains 1.8-2% beryllium and small amounts of nickel, chromium, titanium and other elements. After quenching and aging treatment, its strength can reach 1250-1500MPa, approaching the level of medium-strength steel.
C17200 BERYLLIUM COPPER provides the highest strength of all available copper-beryllium alloys. It has electrical and thermal conductivity considerably greater than other high-strength copper alloys with an ultimate tensile strength that can exceed 200 ksi (1380 MPa), hardness approaching HRC 45, and a minimum electrical conductivity of 22% IACS (International Annealed Copper Standard).
C17200 BERYLLIUM COPPER is available in strip, rod, tube, wire, bar, plate, forging and extrusion forms. C17200 BERYLLIUM COPPER is a versatile material used in a broad range of applications from oil and gas drilling components to aerospace bushings, automotive connectors and computer processor socket contacts.
