Product Information of CuBe2 BrB2 C17200 Beryllium Copper Alloy:
C17200 Beryllium Copper, the full range of beryllium copper is
called " the king of non-farrous metal elasticity".
It is used for all kinds of micro-motor brushes, switches, relays,
connectors, temperature with the increasing requirements for the
reliability and service life of the springs and various springs of
the controller, the demand for beryllium copper will also increse.
C17200 copper's ultimate tensile and Rockwell hardness properties
in a peak aged condition are in the 200 ksi range and RC 45
respectively (electrical conductivity 22% IACS minimum).

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.
