5083 Aluminum Tube/Pipe

Grade: 5083

Size:

Extruded: 6mm*1mm-400mm*40mm

Seamless: 70mm*10mm-270mm*60mm

Forged: 120mm*20mm-1200mm*200mm

Standard: ASTM, AMS, BS etc.

5083 is a non heat treatable aluminum magnesium manganese alloy with higher strength than many general purpose 5xxx grades and good resistance to seawater corrosion. Tube and hollow sections are used in marine, transport and industrial structures, including welded assemblies. O, H111 and H112 conditions balance fabrication needs and strength. Prolonged elevated temperature exposure can promote sensitization and intergranular corrosion; service limits must be assessed. Marine sheet tempers must not be assumed to apply automatically to tube.
