2A12 aluminum rods 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 .
