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).

Normal Name: C17200 Beryllium Copper Alloy

Other Names: Alloy 25 Beryllium Copper Alloy, C172 beryllium copper alloy, DIN 2.1247 Beryllium Copper Alloy, CDA 172 Beryllium Copper Alloy, CuBe2 Beryllium Copper Alloy, etc.

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.
