Excellent Properties of CuBe2 High Copper Alloys Beryllium Copper Alloys:
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.
