Beryllium Copper C17200 Foil Manufacturer and Supplier in India

HOME → Material → Beryllium Copper Products → Beryllium Copper C17200 Foil

Beryllium Copper C17200 Plate is a precipitation-hardenable copper alloy with a high strength, good thermal conductivity and stable dimensional properties. It is identified by designations such as UNS C17200, CDA 172, Alloy 25, CuBe2, and DIN 2.1247. It can be supplied solution annealed Condition A (TB00) to offer much higher ductility of the material to facilitate forming and machining before final condition or hardness. When the process of controlled age hardening has been used, the resulting precipitates of beryllide are in extremely fine form, which greatly improves mechanical properties. The C17200 has a tensile strength of approximately 1550 MPa and hardness of HRC 36-45 (depending on the temper and heat treatment). C17200 BeCu plate is suitable for high performance electrical, aerospace, tooling and industrial parts. Sachin Steel Centre is a manufacturer and supplier of Beryllium Copper C17200 Plate in India supplied to ASTM B194 with the thickness range of 4.8 mm to 150 mm and cut as per your size with EN 10204 3.1 mill test certificate.
