2024 Aluminum Plate

2024 is a high strength aluminum alloy with higher strength than 2011, with adequate work ability. With its high strength and excellent fatigue resistance, it is used to advantage on parts and structures where a good strength-to-weight ratio is desired. 2024 is readily machined at high speeds and gives accurate machining detail with a high finish. 2024 in the annealed condition is easily formed and may be subsequently heat treated. 2024 has good stress corrosion cracking resistance. Since corrosion resistance is relatively low, 2024 is commonly used with an anodized finish or in clad form, with a thin surface layer of high purity aluminum for increased corrosion resistance. Electrical conductivity is 35% of copper


2024 Plate Conforms to ASTM B209, AMS 4035, QQ-A-250/4

2024 is commonly used for structural components, couplings, hydraulic valve bodies, fuse parts, gears and shafts, worm gears, pistons, rectifier parts, missile parts, munitions, fasteners, cap nuts, bolts, hardware, truck wheels, transportation industry parts, computer parts, clock parts, veterinary and orthopedic equipment, and commonly in the aircraft industry for aircraft fittings, fuselage structurals, wing tension members, shear webs and ribs and structural areas where stiffness, fatigue performance and good strength-to-weight ratio is required.


2024 in the T351 condition has a machinability rating of 90% when compared to 2011 at 100%. Machines to a high finish. 2024 is can be formed in the annealed condition. 2024 can be forged or hot worked, however subsequent heat treatment is necessary in order to retain reasonable corrosion resistance. 2024 is a very poor choice for welding. Gas and arc welding is not recommended. 2024 can be spot welded or seam resistance/flash welded. Brazing and soldering is not recommended. Generally welding should be avoided because of the degradation of corrosion resistance that occurs as a result of the weld heat.


2024 is an age-hardening aluminum alloy and responds to heat treatment to accomplish the strengthening (aging). The T4 condition is attained by a 920°F heating followed by a cold water quench and aging at room temperature. T6 is attained by the same 920°F and quenched followed by a 375°F for 10 hours and air cooling.


Annealing is done at 750°-800°F for at least 2 hours at temperature, followed by slow cooling in furnace. This will anneal 2024 from a heat treated condition. Annealing 2024 between cold working operations may be done at 650°F for 2 hours, followed by air cool.


The T4 condition is attained by a 920°F heating and cold water quenching. Aging then occurs at room temperature. For T6 condition, use the same 920°F and water quenching procedure than reheat to 37°F for 10 hours and air cool. Other conditions are a result of the T4 condition followed by controlled amounts of cold working.
