Product Photos:
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.
