Nexalloy 4047 Aluminum MIG Welding Wire

Nexalloy 4047 is 12% silicon all position aluminum weld wire used to weld heat treatable alloys such as the 6XXX base metals and cast alloys. Found in many common welding applications such as bicycles, trucks, trailers, automotive parts and equipment. The higher silicon with this alloy give improved wetting action yielding a less crack sensitive bright weld bead and also a narrow melting range which will reduce the shrinkage during cooling.
