CUBERYLLIUM® manufactures copper beryllium in several distinct compositions. These fall into two categories: alloys selected for high strength (Alloys 172,173,170) and alloys selected for high conductivity (Alloys 751,750,741). And Gost standard QBe2,QBe1.9Ti for Russia Market. Also Supply Master alloy : CuBeryllium-200; CuBeryllium-275);CuBeryllium-350 and Cuberyllium-400 to global factory.

What are the Properties of Beryllium Copper?
Properties of BeCu:
Beryllium copper is a ductile, machinable, and weldable alloy.
BeCu has an excellent response to precipitation-hardening treatments.
BeCu has excellent thermal conductivity (62 Btu/ft-deg.F-H), and it is about 3-5 times more conducting than Tool steel.
It shows resistance to stress relaxation.
It is resistant to non-oxidizing acids such as hydrochloric acid (HCl) and carbonic acid (H2CO3), to plastic decomposition products, to abrasive wear, and galling.
It can be heat-treated for increased strength, durability, and electrical conductivity.
Beryllium copper displays the maximum strength (up to 1,400 MPa (200,000 psi)) of any copper-based alloy.
