When straightening members made of 2024-T4 aluminum, the recommended approach is to straighten them cold and reinforce if necessary. This is because 2024-T4 aluminum is a heat-treated alloy that achieves its high strength through a specific heat treatment process.

Heating this aluminum alloy prior to straightening can compromise its mechanical properties, as the heat may cause the material to lose its temper. In T4 temper, the aluminum is in a solution-treated and artificially aged state, which means that it's already been prepared for maximum strength without additional heating. Straightening at ambient temperature helps maintain the strength characteristics, ensuring the integrity of the material is preserved. If the member is bent or distorted, reinforcing the structure can also help compensate for any loss of capabilities due to stresses induced during the straightening process.

The consideration for cold straightening aligns with the practices used in working with heat-treated aluminum alloys, emphasizing the importance of maintaining their mechanical properties for performance and safety.
