Alloy M25 can be supplied in the form of bar or wire based on different design needs. Also there are different supply states for customers to choose according to different needs. C17300 also has good welding performance, wear resistance and adhesion resistance. It can be forged into parts of various shapes. Beryllium copper c17300 has better strength and wear resistance than chromium zirconium copper alloy.



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.
