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.



Introduction of Material UNS C17500 Copper Alloy:

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

Material Properties


Hard copper alloy with high thermal conductivity amd high mechanical properties combined with good hardness and high temperature strength.

Application Area Spot welding electrodes and seam welding discs for stainless steel, monel and nickel alloys, flash welding dies, wire mesh electrodes, plastic blow and injection moulds and inserts in steel tools for higher cooling rates, nozzles and needles for hot runner systems, plunger tips in aluminum die casting machines, moulds for non-ferrous metal castings (as copper, brass, bronze), welding tools in plastic packaging.
Heat Treatment Delivered in heat treated conditions.

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.
