CUBERYLLIUM® manufactures copper beryllium in several distinct compositions. These fall into two categories: alloys selected for high strength (Alloys 172,173,170) and alloys selected for high conductivity (Alloys 751,750,741). And Gost standard QBe2,QBe1.9Ti(БрБ2;БрБНТ1.9) for Russia Market. Also Supply Master alloy : CuBeryllium-200; CuBeryllium-275);CuBeryllium-350 and Cuberyllium-400 to global factory.

 

CUBERYLLIUM ®-Qbe2 also named Cube2 Beryllium Copper is the most commonly utilized Copper Beryllium alloy and is notable for its highest strength and hardness compared to commercial copper alloys. Qbe2 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. Qbe2 also exhibits exceptional resistance to stress relaxation at elevated temperatures.

 

Chemical Composition of Beryllium Bronze Alloy Qbe2:

Be: 1.80-2.10%

Al: 0.15% Max
Ni: 0.20-0.50%
Fe: 0.15% Max.
Cu: Rest
Note: Copper plus additions equal 99.5% minimum.

 

Available Product Forms of Beryllium Bronze Alloy Qbe2 Round Strips, Round Rods, Bars, Coils, Sheets, Plates
Custom shapes are available upon request.

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.
