2024 Aluminum Tube/Pipe

Grade: 2024

Size:

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

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

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

Standard: ASTM, AMS, BS etc.

2024 is a heat treatable aluminum copper magnesium alloy selected for high strength and fatigue performance. Seamless drawn tube is used in aerospace systems, while extruded tube serves structural and machined applications. T3 combines solution treatment, cold working and natural aging. Corrosion resistance is lower than that of many 3xxx and 5xxx alloys, so protective finishing and service assessment are important. Conventional fusion welding is generally avoided for critical structures because of cracking and strength loss.
