A copper wire containing 3% silicon and 1% manganese used for fusion welding materials of similar
composition, copper alloys (brass) and for MIG brazing steels. The silicon and manganese provide
good flow properties and wear-resistance. It is also suitable for surfacing steel and dissimilar
metal applications. CuSi3 is the choice material for the manufacture and repair of motor vehicles.
Frequently used to weld steels and cast-iron to copper, brass and bronze. Can be used on galvanized steels.
