CUBERYLLIUM® maintains an inventory of beryllium copper alloys, including beryllium copper strips, beryllium copper rods/bars, beryllium copper wires and so on.
The small ratio of beryllium to copper creates a family of high-copper alloys with strength as high as alloy steel. The commercial grades of beryllium copper alloys contain from 0.4 to 2.0% berylliium. The two families consist of high strength with moderate conductivity copper alloy C17200 and C17300, high conductivity with moderate strength copper alloy C17500 and C17510. The principal characteristics of these alloys are their excellent response to precipitation-hardening treatments, excellent thermal conductivity, and resistance to stress relaxation.

Benefits of CuBe2Pb / C17300 (CDA173) 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.
FAQ:
