Melting Point 980-1020°C
Ult Tensile Strength 350N/mm2
Hardness 90

Gas Welding: Oxy/Acetylene
Tig Welding: DC+, 70-320A, Pure Argon 15-20lpm

A copper rod, containing 3% silicon and 1% manganese used for fusion welding materials of similar composition, copper, copper alloys (brass) and for TIG brazing steels.

It is also suitable for surfacing steel and dissimilar metal applications.

Excellentperformance on galvanized steel and provides good corrosion-resistance.

Suitable for use in the ship building/offshore industries as well as the heating and ventilation industries for corrosion resistance, and tubular product fabrication.

Can also be used for sculpture repair.

Oxy-acetylene gas flame should be slightly oxidizing.

Keep the weld puddle small in order to promote fast solidification and minimize cracking.

In oxy-acetylene welding, flux should be used both before and during welding.
Preheat is not recommended.

Can be used in oxy-acetylene for fusion welding of copper alloys and brass.

Also popularly used in TIG for brazing steel and cast iron to copper, brass and bronze.
