Corrosion resistance is not high, often with anodized and painted or surface plus clad layer method to improve corrosion resistance.

Thermal state, annealing and quenching conditions forming the new performance is better than the heat treatment significantly enhanced the effect with, but the heat treatment process demanding poor corrosion resistance, but with aluminum coating can be effectively protected;. easy to crack when welding, but can be welded using a special process to be riveted aluminum bar 2024 is a high-strength aluminum hard. , can be heat strengthened, just in the quenched and quenched plastic medium, spot welding is good, tends to be formed between the intergranular cracks with welding, the alloy after quenching and work hardening their cutting performance is good, can be cut after annealing low: corrosion resistance is not high, often with anodized and painted surface plus clad layer method or to improve its corrosion resistance.
