2024 Aluminum Bar and Rod

Grade: 2024

Size:

Cold drawn: 2mm-12mm

Extruded: 6mm-400mm

Standard: ASTM, AMS, BS etc.

2024 is a heat treatable aluminum copper magnesium alloy selected for high strength and fatigue performance. Bar and rod are widely used as stock for aerospace fittings and precision machined components. Naturally aged T4 and T351 conditions combine useful ductility with strength, while artificially aged conditions increase yield strength. Corrosion resistance is lower than that of many 5xxx and 6xxx grades, making protective finishes important. Conventional fusion welding is generally avoided in critical structures because of cracking and strength loss.
