3004 aluminum sheet belongs to Al-Mn series alloy, is a kind of rust-proof aluminum sheet with a wide range of application. 3004 aluminum sheet has a low intensity(higher than pure aluminum), can not be strength by heat treatment, but its mechanical properties able to improved by cold processing technique. 3004 aluminum sheet has a good corrosion resistance, a good weldability but a poor cutting property, it has a high plasticity in annealed condition, and has a low plasticity in cold-work hardening. 3004 aluminum sheet is usually used in the low-load spare parts that work in liquid or gaseous media, and has the requirements of a high plasticity, good weldability, such as the mailbox, petrol or lube ducts, various liquid containers and other small load parts.
3004 aluminum sheet belongs to series 3xxx that process by hot rolling, it has many advantages, like a good color printing performance, a high stamping elongation and a good intensity. 3004 aluminum sheet is widely used in cans, such as China’s well-known enterprises Tsing Tao beer and Wong Lo Kat, both of them are use 3004 aluminum sheet from haomei aluminium.
