Product Normal Description:
Product Name: Beryllum copper round rods
Grade: RWMA Class 3
Size: 16mmdia. x 2000mml
State: HT
Typical Application: Industry
Product Brand: CUBERYLLIUM®
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.
Beryllium copper has its reasonable share of common names. You will
listen referred to as BeCu, Copper Beryllium, Beryllium Bronze, and
Spring Copper. Anytime you hear those terms, they're in reference
to Beryllium Copper. Beryllium round bars are accessible as high
strength and high conductivity alloys.
CUBERYLLIUM ®-751 also named -C17510 (CDA 1751) combine moderate yield strength, up to 960Mpa(140ksi), with
electrical and thermal conductivity from 45 to 60 % of pure copper.
Alloys 750 and 751 are available in wrought product forms and can
be supplied fully hardened. Hardened products are identified by the
temper designation AT or HT, and have good formability.

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.
