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.
