1. Introduction à la 2A12 Matériaux
2A12 aluminum alloy Al-Cu-Mg aluminum alloy, main features and application range: This is a hard aluminum, which can be strengthened by heat treatment. It has medium plasticity in quenching and rigid quenching states, good spot welding, and tends to form intergranular cracks when using gas welding. The alloy has good cutting performance after quenching and cold hardening, and has low machinability after annealing: low corrosion resistance, and often uses male oxidation treatment and paint coating methods or an aluminum coated layer on the surface to improve its corrosion resistance.
Standard: GB/T 3191-2010 Replaces old GB/T 3191-1998
