ER4043 is a general-purpose, all-position aluminum welding

 wire used to weld various grades of aluminum . It contains 

silicon additives, which may improve fluidity of the weld pool 

and also produces a weld less sensitive to cracking. 

Its bright weld finish makes it a popular choice of welders.
