OK Autrod 19.40 GMAW
ERCuAl-A1
Description
A continuous, solid, copper wire for the GMA joining
of aluminium bronzes.
OK Autrod 19.40 is alloyed with aluminium and is
recognised for its high strength, good wear resistance
and very good corrosion resistance, particularly
in salt water. The alloy is widely used for
joining corrosion-resistant pipes made of aluminium
bronze or other special brass alloys. Other
common applications include the overlay welding
of bearings, ship's propellers and rails. OK Autrod
19.40 is normally welded with pure Ar as the
shielding gas.
