Introduction of Beryllium Copper Alloy:
Beryllium copper is a copper alloy with 0.5-3% beryllium and sometime with other alloying elements. Beryllium copper alloy combines high strength with non-magnetic and non-sparking qualities. Beryllium copper has excellent metalworking, forming and machining qualities.
Beryllium copper has many specialized applications in tools for hazardous environments, musical instruments, precision manufacturing due their toxic properties.
Typical Application of Beryllium Copper Alloy Qbe2:
- Electrical Industry: Electrical switch and Relay blades, Fuse clips, Switch parts, Relay parts, Connectros, Spring Connectors, Contact bridges, Belleville washers, Navigational instruments, Clips, EMI finger stock;
- Industrial: Pumps, Springs, Electrochemical, Shafts, Non-sparking safety tools, Flexible metal hose, Housings for instruments, Bearings, Bushings, Valve Seats, Valve Stems, Diaphragms, Springs, Welding Equipment, Rolling Mill Parts, Spline Shafts, Pump Parts, Valves, Bourdon Tubes, Wear Plates on Heavy Equipment, Bellows.

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.
