C17200 Beryllium Copper Alloy Performance:
1. Beryllium copper is a precipitation hardning alloy. After
solution aging treatment, it will have high hardness, elastic limit
and fatigue limit, corrosion resistance and processing properties,
it also has high strength.
2. It has good fluidity and the ability to reproduce fine patterns.
Due to the many superior properties of beryllium copper alloy, it
has been widely used in the manufacturing industry.
3. It has strong electrical conductivity.
4. The product specifications are complete, the price is favorable,
the packaging is intact, the copper is pure, the straightness is
good, the inventory is large, and the material certificate and SGS
report can be provided.

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.
