Frame parts 2A12-T6 aluminum rods on aircraft
Product introduction of aluminum alloy bar
2A12 aluminum rod characteristics and application:
2A12 aluminum alloy is a kind of high-strength hard aluminum, which can be strengthened by heat treatment. It has moderate plasticity in annealing, just quenching and hot state, 2A12 aluminum alloy Xin spot welding has good weldability, and there is an intercrystalline crack formed by gas welding and argon arc welding. Tendency; 2A12 aluminum alloy has good machinability after quenching and cold hardening, poor corrosion resistance in the annealed state, often using anodizing and painting methods or surface coating of aluminum to improve corrosion resistance .
2A12 aluminum rod chemical composition:
Fe： 0.000～ 0.500
Fe+Ni： 0.000～ 0.500
2A12 aluminum rod mechanical properties:
Tensile strength (MPa): ≥390
Conditional yield strength 0.2 (MPa): ≥255
Elongation : ≥5 (%)
2A12 aircraft skins, bulkheads, wing ribs, spars, rivets, etc., construction and transportation tool structures
