2A12 T351 aluminium square flat bar

2A12 T351 aluminium square flat bar is a kind of high-strength hard aluminum, which can be strengthened by heat treatment; 2A12 aluminum alloy has good spot welding and has a tendency to form intergranular cracks when using gas welding and argon arc welding; 2A12 aluminum alloy can be cut after cold work hardening Performance is good. The corrosion resistance is not high, and anodizing treatment and painting methods are often used, or the surface is coated with aluminum layer to improve the corrosion resistance.
