Description
4043 is one of the most widely used welding and brazing alloys and can be classed as
A general purpose filler alloy
The silicon addition results in improved fluidity (wetting action), making the alloy the preferred
The alloy is not sensitive to weld cracking and produces bright, almost smut-free welds
Not recommended for anodising
Non-heat treatable
Welding current: DC(+)
