Hobart® MaxalMig® 5183
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
