CUBERYLLIUM® manufactures copper beryllium in several distinct compositions.

These fall into two categories: high strength beryllium copper alloys 172(UNS. C17200),173(UNS. C17300),170(UNS. C17000), and copper alloys selected for high conductivity 751(UNS. 17510),750(UNS. 17500),741(UNS. 17410).

We also Supply Master alloy : CuBeryllium-200, CuBeryllium-275, CuBeryllium-350 and Cuberyllium-400 to global factory.

CUBERYLLIUM ®-172 also named Cube2--UNS. C17200 (CDA 172) Beryllium Copper is the most commonly utilized Copper Beryllium alloy and is notable for its highest strength and hardness compared to commercial copper alloys. C17200 alloy contains appr. 2% of beryllium and achieves its ultimate tensile strength can exceed 1360Mpa, while the hardness approaches Rockwell C45. Meanwhile, the electrical conductivity is a minimum of 22% IACS in the fully aged condition.C17200 also exhibits exceptional resistance to stress relaxation at elevated temperatures.

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.
