3003 alloy is an aluminum alloy with manganese as the main alloying element. It has good corrosion resistance to atmospheric, fresh water, sea water, food, organic acid, gasoline, neutral inorganic salt aqueous solution, etc., and corrosion resistance in dilute acid. Very good, so there is a reputation of "king of rust". The chemical composition of the 3003 alloy is: silicon Si: 0.60 iron Fe: 0.70 copper Cu: 0.05-0.20 manganese Mn: 1.0-1.5 zinc Zn: 0.10 Other: single 0.05, total 0.15 aluminum Al: balance.
