Welding Wire ER4043 can use where base metal requires thermal treatment. It also can be used on weld forge and casting materials.
Commonly referred to as “AlSi5", has a 5% silicon. It contains silicon additions, improving the weld pool's fluidity and making the welding less sensitive to cracking. The bright finish is a good choice for welders
