Product Brand: CUBERYLLIUM®
CUBERYLLIUM® is a professional supplier of various beryllium copper alloys, including beryllium copper strip, beryllium copper rod, beryllium copper wire and other copper alloys.
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.
Chemical Composition of Beryllium Copper Alloy C17200 (CUBERYLLIUM ®-172):
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.
