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.
