ESAB OK Autrod 19.40 welding wire 1.2mm 15kg

Continuous, homogeneous copper wire for aluminum bronze product welding by GMA method.

OK Autrod 19.40 is alloyed with aluminum and valued for its high strength, good wear resistance, and very good corrosion resistance, especially in salty water. The alloy is widely used to join corrosion-resistant aluminum bronze or other special brass alloy tubes. It is also frequently used for the surfacing of bearings, ship propellers, and gears. OK Autrod 19.40 is typically welded using Ar as a shielding gas.
