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.

Introduction of C17300 Beryllium Copper Alloy:

C17300 (M25) high-strength Copper Beryllium Alloy is nearly identical to C17200/CuBe2, but with a small percentage of lead added strictly to increase machinability performance for high speed screw machining.

Alloy C17300 Alloy M25 Copper Beryllium, which gets its strength from precipitation heat treating, is used typically in round insertion connector and sensor, RWMA applications in the aerospace, oil and gas, marine, performance racing, and plastic mold tooling industries, non-sparking safety tools, flexible metal hose, bushings, electro-chemical springs and bellows.

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.
