  • Heat treatment of beryllium bronze

    introduction:Beryllium bronze is a precipitation-hardening alloy with a wide range of applications。After solution and aging treatment,Strength up to1250-1500MPa(1250-1500kilogram)。Its heat treatment characteristics are:It has good plasticity after solution treatment,It can be deformed by cold working。But after aging treatment,But it has a very good elastic limit,Simultaneous hardness、The strength is also increased。 (1) Solution treatment of beryllium bronze General solution treatment heating temperature in780-820℃among,For materials used as elastic components,adopt760-780℃,It is mainly to prevent the coarse grain from affecting the strength。
