5182 aluminium tubes are used in applications requiring lightweight, corrosion-resistant structural sections, including automotive components, marine tubing, fuel delivery lines, industrial machinery, and custom fabrication work where 5xxx series alloys are preferred for weldability and corrosion resistance.
Primary Characteristics:
Excellent corrosion resistance due to high magnesium content (~4.0–5.0 %)
Medium strength and weldability suitable for structural and fabricating applications
Lightweight and durable, ideal for lightweight engineering parts with moderate loads
Good formability and surface finish, supports extrusion and drawing processes
Typical Product Application:
5182 aluminium tubes are used in applications requiring lightweight, corrosion-resistant structural sections, including automotive components, marine tubing, fuel delivery lines, industrial machinery, and custom fabrication work where 5xxx series alloys are preferred for weldability and corrosion resistance.
