OK Autrod 4043 GMAW
ER4043
Description
OK Autrod 4043 is one of the most widely used
welding and brazing alloys and can be classified
as a general-purpose filler alloy. The silicon addition
results in improved fluidity (wetting action),
making the alloy the preferred choice of welders.
The alloy is not sensitive to weld cracking and
produces bright, almost smut-free welds. Not
recommended for anodising. Non-heat treatable.
