(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.
CUBERYLLIUM ®-751 also named -C17510 (CDA 751) Alloy 751 is a high conductivity copper beryllium alloy used in
applications requiring a combination of high thermal conductivity
with moderate strength. Alloy 751, supplied with certified
mechanical properties, is fully heat treated and no additional
treatment is required. Alloy 751 is nonmagnetic and provides
excellent resistance to thermal fatigue.

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.
