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.
Beryllium copper has its reasonable share of common names. You will listen referred to as BeCu, Copper Beryllium, Beryllium Bronze, and Spring Copper. Anytime you hear those terms, they're in reference to Beryllium Copper. Beryllium round bars are accessible as high strength and high conductivity alloys.
CUBERYLLIUM ®-751 also named -C17510 (CDA 1751) combine moderate yield strength, up to 960Mpa(140ksi), with electrical and thermal conductivity from 45 to 60 % of pure copper. Alloys 750 and 751 are available in wrought product forms and can be supplied fully hardened. Hardened products are identified by the temper designation AT or HT, and have good formability.

Good hot working properties. Excellent cold working properties.
Key Technology of Beryllium Copper(Heat treatment)
Age Hardening
Age hardening significantly enhances the material’s strength. This reaction is generally carried out at temperatures between 260°C and 540°C depending on alloy and desired characteristics. This cycle causes the dissolved beryllium to precipitate as a beryllium rich (gamma) phase in the matrix and at the grain boundaries. It is the formation of this precipitate which causes the large increase in material strength. The level of mechanical properties attained is determined by the temperature and time at temperature. It should be recognized that beryllium copper has no room temperature aging characteristics.
