The strength of this alloy is not high (slightly higher than industrial
pure aluminum) and cannot be strengthened by heat treatment, so cold
working methods are used to improve its mechanical properties: high
plasticity in the annealed state, still good plasticity in the semi-cold
work hardening, low plasticity in the cold work hardening, good
corrosion resistance, good weldability, poor machinability. Uses are
mainly used for the requirements of high plasticity and good weldability,
low load parts working in liquid or gas medium, such as oil tanks,
gasoline or lubricating oil conduits, various liquid containers and
other small load parts made by deep drawing, wire used to make rivets.
