1.3004 aluminium alloy is an alloy in the wrought aluminium-manganese family (3000 or 3xxx series). It is similar to the 3003 alloy, except for the addition of approximately 1% magnesium. It can be cold worked (but not, heat treated) to produce tempers with a higher strength but a lower ductility. Like most other aluminium-manganese alloys.

3004 aluminum alloy foil is of medium strength.It is widely used for making cans,bottles,wine bottle lids etc. It was developed to satisfy the need for thinner gauges in can-stock, and thereby to some extent replaced its predecessor 3003 alloy in the making of beverage cans. Can-stock can be made thinner due to the addition of 1% magnesium, which contributes in solid solution strengthening.
