5356 aluminum MIG welding alloy is an all-position, non-heat treatable MIG wire used to weld the 5XXX series alloys when 40,000 psi tensile strength is not a requirement. Alloy 5356 is a very good all-purpose wire. It is the most widely used of all aluminum filler metals. Common applications are welding of boats/ships, bicycles, trucks, pressure vessels and automotive parts. Features Used mainly for welding aluminum of like composition. This type is also useful if color match is important after anodizing. Should be considered for welding 5000 series aluminum base metals. Optimized To Reduce Fumes & shaved for ultimate cleanliness of wire. 5359 offers excellent corrosion resistance when exposed to salt water AWS Classification A5.13 5356 aluminum/silicon GMAW (MIG) welding alloy Designed for welding heat treatable base alloys, specifically 6XXX series alloys Lower melting point and more fluidity than 5XXX series filler alloys Low sensitivity to weld cracking with 6XXX series base alloys Suitable for sustained elevated temperature service, i.e. above 150°F (65°C) All position, except vertical down welding Gray (post anodized) color Applications Automotive bumpers and supports Structural frames in the shipbuilding industry Formed truck panels Railing Industry Power Industry Trailer Manufacturing
