CUBERYLLIUM Brand 741 C17410 Strip Size 0.35x200mm by ASTM B768 for
spring contacts
Product Name: CUBERYLLIUM Brand Strip
Grade: C17410
Size: 0.35mmx200mm, Or as customers' requirement
State: 1/2 HT(TH02), HT(TH04)
Product Informance of CUBERYLLIUM® Company:
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 for Russia
Market. Also Supply Master alloy : CuBeryllium-200;
CuBeryllium-275);CuBeryllium-350 and Cuberyllium-400 to global
factory.
CUBERYLLIUM ®-741 also named -C17410 Copper alloy with low beryllium content. It contains only few
alloy elements: Beryllium and cobalt. Alloy 741, C17410 combines
outstanding electric conductivity with high mechanical strength
(typical values: 50% et 750N/mm2 .
Alloy 741 is supplied hardened so that a later heat treatment of
the products is not necessary. This reduces production costs and
prevents the deformation of the finished products. Although alloy
741 is supplied in hardened condition, it shows excellent bending
behavior. This alloy distinguishes by excellent bending behavior in
connection with mechanical strength and conductivity, which
outperforms any other copper alloy of this price level.

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 mill 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.
