Technical Regulation and Scope of ASTM B870
This international standard defines the supply technical specifications for forgings and stampings produced from high-strength copper-beryllium alloys of grades UNS C17500, C17510, and C17540. The manufacturing process includes hot working or extrusion methods, mandatory solution heat treatment, as well as subsequent precipitation hardening and final straightening to ensure geometric precision of the products.
EV Group China guarantees full compliance of the supplied products with the requirements of the ASTM B870 standard, including strict control of the chemical composition, physical and mechanical properties, and electrical conductivity of the alloys. Our technological processes ensure the stability of metal characteristics, which is critical for critical components in the aerospace, oil and gas, and electronics industries.
