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.
