Excellent cold and hot deformability. This alloy is used wherever electrical and thermal conductivity is required requiring besides good mechanical properties such as: injection pistons, spot / boss welding. Inserts for heat exchange and electrical conductivity


Cold chamber injection pistons, plates for boss welding, and parts of molds for plastic injection or cooling noses.
