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.

Weldability
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.
