CUBERYLLIUM®-172 is the most commonly specified copper beryllium ,In its age hardened condition, CUBERYLLIUM®-172 attains the highest strength and hardness of any commercial copper base alloy. The ultimate tensile strength can exceed 1360Mpa(200 ksi), while the hardness approaches Rockwell C45. Also, in the fully aged condition, the electrical conductivity is a minimum of 22% IACS (International Annealed Copper Standard). Alloy 172 also exhibits exceptional resistance to stress relaxation at elevated temperatures.

FAQ:
Q1:What’s the advantages the Beryllium Copper of CUBERYLLIUM®?
A1: 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.
Q2: Why you melting by Vacuum semi-Continuous Furnace?
A2:Could be get the Cast ingot without gas,smaller segregation, Grain Refinement.
Q3:Could you produce Beryllium Copper strip by Mill Hardened process?
A3: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.
Q4: What's the payment terms?
A4: We accept T/T, L/C, Paypal etc. It can be negotiated when the amount is different.
