LY12 is an old grade, while the new grade is 2A12. It is a high-strength hard aluminum that can be heat treated and strengthened. It has moderate plasticity in both annealed and quenched states, good spot welding performance, and a tendency to form intergranular cracks when using gas welding and argon arc welding; The machinability of alloys is still good after quenching and cold work hardening, but low after annealing; The corrosion resistance is not high, and anodizing and painting methods or surface aluminum coating are often used to improve its corrosion resistance. LY12 latest execution standard GB/T3880-2006 density 2.78g/cm3 tensile strength ≥ 425.2A12 extruded aluminum rod manufacturer Hongxiang Aluminum Industry serves you!
