Hobart MaxalMig 5183 description: 5183 filler metal is the most common aluminum/magnesium alloy for welding 5083 base metal in ship building applications. 5183 has higher strength values than 5356 with excellent salt water corrosion resistance when welded to 5083. Features/Benefits: - Very high strength (41 ksi typical) - High ductility/toughness/fatigue strength - Moderate ductility/formability - Lower electrical conductivity and thermal conductivity - Excellent corrosion resistance when welding 5083 base material - Higher column strength/better feedability - Very good color match after anodizing with 5xxx/6xxx base materials.
