Key Technology of Beryllium Copper(Heat treatment)
Age Hardening
Age hardening significantly enhances the material’s strength. This
reaction is generally carried out at temperatures between 260°C and
540°C depending on alloy and desired characteristics. This cycle
causes the dissolved beryllium to precipitate as a beryllium rich
(gamma) phase in the matrix and at the grain boundaries. It is the
formation of this precipitate which causes the large increase in
material strength. The level of mechanical properties attained is
determined by the temperature and time at temperature. It should be
recognized that beryllium copper has no room temperature aging
characteristics.
FAQ:
Q1:Could you produce Beryllium Copper strip by Mill Hardened
process.
A1:Yes, we could produce AM(TM00), 1/2HM(TM01).HM(TM04) XHM(TM06)
XHMS(TM08).,we are the only factory could do harden strip in China.
Q2: What’s the advantages the Beryllium Copper of CUBERYLLIUM®.
A2: 1: The Biggest Coil weight could be reach 1200kg/Coil
2:We are the only one who melting by Vacuum semi-Continuous
Furnace.
