Abratig CuSi3
TIG filler metal CuSi3
Product description
Copper-silicon alloy TIG wires
Applications: Copper, low-alloy copper and copper-zinc alloys, as well as the hardfacing of unalloyed and low-alloy steels and cast iron.
Product application instructions
Preheating of the base material is generally unnecessary. Avoid over-extending the weld pool. When cladding ferrous materials, introduce as much filler metal as possible into the arc.
