AL 3003 is an alloy with very good corrosion resistance and moderate strength. It is not heat treatable and develops strengthening from cold working only. Main tempers for aluminum foil 3003 includes H 18, H22, H24 and other tempers upon request. This alloy provides a better heating and cooling environment so that widely used in household applications. HTMM Aluminium is a leading aluminum manufacturer mainly in business of 3003 household foil, container foil, packaging foil as well as electronic foil since 2009.
