A
small addition of Zr to copper improves resistance to softening
and resists deformation at high temperatures where normal copper
would soften rapidly. Zirconium Copper is used as a Class 1
electrode material to minimize sticking when resistance spot
welding galvanized materials. Zirconium Copper is also used in
many high temperature applications; i.e. aerospace, power
generation, etc.

Cadmium addition to copper increases hardness and resistance to
softening. C16200 is utilized in numerous applications where
fatigue strength and high electrical conductivity are required.
Cadmium Copper is also specified for spot welding aluminum; the
high thermal conductivity helps to prevent electrode sticking on
these soft, conductive materials.

Chromium copper is the primary copper alloy used for resistance
spot and seam welding. This alloy achieves good hardness and
electrical conductivity though a combination of heat-treatment
and cold work. C18200 is utilized for electrodes, holders,
adaptors, as well as numerous electrical applications where
resistance to deformation at high temperature is required or
when higher mechanical properties than C11000 are required.
