The Aluminum Welding Wire 4043 is a popular choice for welding on 6XXX base materials and heat treatable alloys. Made of a soft alloy, it offers excellent crack resistance and deep penetration when compared to other filler metals. In addition to its welding capabilities, this wire can also be used for certain brazing applications and is suitable for welding on high silicon casts like A356. It is important to note that using 4043 with 5XXX alloys and other 4XXX filler metals is not recommended.
