Aluminum 2024
Aluminum alloy 2024 is an exceptionally high mechanical strength alloy, suitable for parts that require more strength while remaining lightweight. It also has excellent fatigue and cracking resistance, making it a desirable material for aircraft components. Aluminum 2024 can be machined to a high finish.
Aluminum 2024 has a machining cost factor of 0.7 when compared to steel 12L14. It can be forged and hot worked, but is not ideal for welding or soldering. 2024 responds well to heat treatment, annealing, and tempering. It can be anodized, but results in a darker and less corrosion resistant finish than Aluminum 6061.
