The principle characteristics of alloy 172 are an excellent response to precipitation-hardening treatments, excellent thermal conductivity, and resistance to stress relaxation. The high strength beryllium coppers C172 can be purchased in the solution annealed or cold worked tempers and can be easily formed or machined. A low-temperature heat treatment (600 degrees for 2-3 hours) produces maximum strength and hardness. C17200, also commonly known as Alloy 25, CuBe2, is available in round rod, bar, tube, strip, and wire.

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.
