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(+)
