State: 1/2 HT(TH02), HT(TH04)
Product Informance of CUBERYLLIUM® Company:
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 ®-741 also named -C17410 Copper alloy with low beryllium content. It contains only few alloy elements: Beryllium and cobalt. Alloy 741, C17410 combines outstanding electric conductivity with high mechanical strength (typical values: 50% et 750N/mm2 .
Alloy 741 is supplied hardened so that a later heat treatment of the products is not necessary. This reduces production costs and prevents the deformation of the finished products. Although alloy 741 is supplied in hardened condition, it shows excellent bending behavior. This alloy distinguishes by excellent bending behavior in connection with mechanical strength and conductivity, which outperforms any other copper alloy of this price level.

Health and Safety
Processing beryllium-containing alloys poses a health risk if safe practices are not followed. Inhalation of airborne beryllium can cause serious lung diseases in some individuals. Occupational safety and health regulatory agencies worldwide have set mandatory limits on occupational respiratory exposures. Read and follow the guidance in the Safety Data Sheet (SDS) before working with this material.

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 mill 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.
