SM ER 4043

DETAILS

Features/Characteristics

SM ER 4043 is a 5% silicon, all position aluminium weld wire used to weld heat treatable alloys such as the 6XXX base metals cast alloys. It can be found in many common welding applications, such as bicycles, trucks, trailers, and automotive parts and equipment. Silicon with this alloy gives improved wetting action yielding a less crack sensitive bright weld bead. The silicon gives improved wetting action and lowers the crack sensitivity. It is preferred by most welders because it “wets and flows better” and it also brighter looking GMAW welds. This filler metal is not well suited for welding aluminium-magnesium alloys (5XXX alloys).
