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.
CUBERYLLIUM ®-750 also named -C17500 (CDA 750) 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.

Weldability
Soldering, brazing, gas shielded arc welding, coated metal arc
welding, spot welding, seam welding and butt welding are all
recommended
Hot & Cold Workability
Good hot working properties. Excellent cold working properties.
Key Technology of Beryllium Copper(Heat treatment)
Age Hardening
Age hardening significantly enhances the material’s strength. This
reaction is generally carried out at temperatures between 260°C and
540°C depending on alloy and desired characteristics. This cycle
causes the dissolved beryllium to precipitate as a beryllium rich
(gamma) phase in the matrix and at the grain boundaries. It is the
formation of this precipitate which causes the large increase in
material strength. The level of mechanical properties attained is
determined by the temperature and time at temperature. It should be
recognized that beryllium copper has no room temperature aging
characteristics.
FAQ:
Q1:Could you produce Beryllium Copper strip by Mill Hardened
process.
A1:Yes, we could produce AM(TM00), 1/2HM(TM01).HM(TM04) XHM(TM06)
XHMS(TM08).,we are the only factory could do harden strip in China.
Q2: What’s the advantages the Beryllium Copper of CUBERYLLIUM®.
A2: 1: The Biggest Coil weight could be reach 1200kg/Coil
2:We are the only one who melting by Vacuum semi-Continuous
Furnace.
3:Surface further polishing for top clients.
Q3: Why you melting by Vacuum semi-Continuous Furnace.
A3:Could be get the Cast ingot without gas,smaller segregation,
Grain Refinement
Q4: What's the payment terms?
A4: We accept T/T, L/C, Paypal etc. It can be negotiated when the
amount is different.
