Product Specification: 0.28mmx100mm
State: XHMS
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):
