3003 aluminum alloy is an AL-Mn series alloy and is the most widely used rust-resistant aluminum. This alloy has low strength (slightly higher thanIndustrial pure aluminum), cannot be strengthened by heat treatment, so cold processing methods are used to improve its mechanical properties:Annealing stateIt has high plasticity, in the halfCold hardeningThe time plasticity is good, while the cold hardening time plasticity is low, and corrosion resistance is excellent.WeldabilityGood, but poor machinability. It is mainly used for high-demand plasticity and good weldability, in liquids orGas mediumLow-load components used in manufacturing, such as fuel tanks, gasoline or lubricating fluid conduits, various liquid containers, and othersDeep pullSmall load-bearing parts produced, where the wire is used for manufacturingrivet.
