Chemical Composition of CuBe2 Beryllium Copper Alloys:
Beryllium(Be): 1.80-2.00%
Cobalt(Co) + Nickel(Ni): 0.20% Min
Cobalt(Co) + Nickel(Ni) + Iron(Fe): 0.60% Max
Lead: 0.02% Max
Copper(Cu): Balance
Note: Copper plus additions equal 99.5% Minimum.
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.
