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 ®-170 also named Cube1.7-C17000 (CDA 170) Beryllium Copper is a lightly alloyed grade of copper, formulated for primary
forming into wrought products. CW100C is the EN numeric designation
for this material. Alloy170 is the UNS number. Additionally, the EN
chemical designation is CuBe1,7. And the British Standard (BS)
designation is CB101. Older literature may refer to this material
as ASTM Alloy 165, but this is now discouraged.
It has a moderately low electrical conductivity among wrought
coppers. In addition, it has a moderately low melting temperature
and a moderately low thermal conductivity.
The properties of Alloy170 copper include fourteen common
variations. This page shows summary ranges across all of them. For
more specific values, follow the links immediately below. The graph
bars on the material properties cards further below compare Alloy
170 copper to: wrought coppers (top), all copper alloys (middle),
and the entire database (bottom). A full bar means this is the
highest value in the relevant set. A half-full bar means it's 50%
of the highest, and so on.

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
