3003 is the most widely used of all aluminum alloys. It is essentially commercially pure aluminum with the addition of manganese which increases the strength some 20% over the 1100 grade. Thus, it has all the excellent characteristics of 1100 with higher strength. It has excellent corrosion resistance.

3003 series aluminum plate is a popular product in the aluminum-manganese alloy series. Due to the manganese alloy element, this product has excellent rust-resistant properties and is also known as rust-resistant aluminum sheet.
3003 for AL-Mn system alloy, is the most widely used one kind of rust-proof aluminum, the strength of this alloy is not high (slightly higher than the industrial pure aluminum), can not be heat-treated to strengthen, so the use of cold processing methods to improve its mechanical properties: in the annealed state has a very high plasticity, in the semi-cold hardening of plasticity is still good, cold hardening of plasticity is low, corrosion resistance is good, good weldability, machinability is not good. Uses are mainly used for the requirements of high plasticity and good weldability, working in liquid or gaseous media in the low load parts, such as fuel tanks, gasoline or lubricating oil conduit, a variety of liquid containers and other small loads with the production of deep drawing parts: wire used to make rivets.
