2024 Round Bar

2024 is a high strength, fatigue-resistant aluminum alloy used by the motorsports and aircraft industries for structural applications. It has good machinability, and good corrosion in non-industrial atmospheres, but poor corrosion resistance in marine applications. 2024 is available from AED in bars, sheets, and plates. 2024 is sometimes used in place of 7075.
