Specification: According customers' requirement

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.

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.
