Aluminum alloy plate, generally rust-proof aluminum alloy plate, can not be strengthened by heat treatment, cold deformation of alloy can improve the strength. The plasticity of annealed state is high, the alloy has good corrosion resistance and good weldability. High corrosion resistance, machinability in annealing state is poor, semi-cold hardening machinability is good, the manufacture of rivet needs anodizing treatment.

Aluminum alloy plate is a widely used aluminum alloy products, the strength of this alloy is high, especially with fatigue strength: plasticity and corrosion resistance is high, can not be strengthened by heat treatment, in the semi-cold hardening plasticity is good, cold hardening plasticity is low, good corrosion resistance, good weldability, bad machinability, polishing. Mainly used for requiring high plasticity and good weldability, low load parts working in liquid or gas medium, such as oil tank, gasoline or lubricating oil conduit, various liquid containers and other small load parts made with deep drawing: wire used to make rivets.
