CUBERYLLIUM® manufactures copper beryllium in several distinct compositions.
These fall into two categories: high strength beryllium copper
alloys 172(UNS. C17200),173(UNS. C17300),170(UNS. C17000), and
copper alloys selected for high conductivity 751(UNS.
17510),750(UNS. 17500),741(UNS. 17410).
We also Supply Master alloy : CuBeryllium-200, CuBeryllium-275,
CuBeryllium-350 and Cuberyllium-400 to global factory.
CUBERYLLIUM ®-172 also named Cube2--UNS. C17200 (CDA 172) Beryllium Copper is the most commonly utilized Copper Beryllium
alloy and is notable for its highest strength and hardness compared to commercial copper alloys. C17200 alloy contains appr. 2% of
beryllium and achieves its ultimate tensile strength can exceed
1360Mpa, while the hardness approaches Rockwell C45. Meanwhile, the
electrical conductivity is a minimum of 22% IACS in the fully aged
condition.C17200 also exhibits exceptional resistance to stress
relaxation at elevated temperatures.
Chemical Composition of Highest Strength Beryllium Copper Alloys (CUBERYLLIUM ®-172):
Product Grade: CUBERYLLIUM ®-172(UNS. C17200)
Beryllium(Be): 1.80-2.00%
Cobalt(Co) + Nickel(Ni): 0.20% Min
Cobalt(Co) + Nickel(Ni) + Iron(Fe): 0.60% Max

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..
