Food Grade 3003 Aluminum Foil


Product introduction of Food Grade 3003 Aluminum Foil

Good formability, good rust and corrosion resistance, good weldability and plasticity

3003 is an AL-Mn alloy, which is the most widely used rust-proof aluminum. The strength of this alloy is not high (slightly higher than industrial pure aluminum), and it cannot be heat-treated and strengthened. Therefore, cold working method is used to improve its mechanical properties: It has high plasticity in annealing state, good plasticity in semi-cold work hardening, low plasticity in cold work hardening, good corrosion resistance, good weldability and poor machinability. Uses are mainly used for low load parts requiring high plasticity and good weldability in liquid or gaseous media, such as fuel tanks, gasoline or lube oil conduits, various liquid containers and other small load parts made with deep drawing: Wire is used to make rivets.

3003 aluminum foil has good formability, solvability and corrosion resistance. It is used to process parts that require good formability, high corrosion resistance and good weldability, or to meet the production requirements that require both these properties and higher strength than the 1 series alloy.
