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 UNS.C17300 Leaded Beryllium Copper Alloys:

C17300 copper is a lightly alloyed grade of copper, formulated for primary forming into wrought products. CW102C is the EN numeric designation for this material. C17300 is the UNS number. Additionally, the EN chemical designation is CuBe2Pb.

It has a moderately low electrical conductivity among wrought coppers. In addition, it has a moderately low melting temperature and can have a moderately high tensile strength.

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.
