Introduction of CuNi2Be (C17510) Beryllium Copper Alloy:

C17510(Class 3) Copper Alloy is specifically recommended for projection welding dies, flash and butt welding dies, current carrying shafts, and bushings. Since they have higher strength than Class 2, C17510 is recommended for highly stressed welder structural current carrying members and heavy duty offset electrode holders.


Cl17510(Class 3) Copper Alloy is generally recommended for spot welding and seam welding steels, such as stainless steel, since it has high electrical resistance. The C17510 alloy is heat treatable.

Soldering, brazing, gas shielded arc welding, coated metal arc welding, spot welding, seam welding and butt welding are all recommended


Hot & Cold Workability

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.
