High-quality 3004 aluminum sheet supplier offering excellent strength, formability, and corrosion resistance. Ideal for beverage cans, food packaging, roofing, and industrial applications. Factory-direct pricing and custom sizes available.
3004 aluminum sheet belongs to the aluminum-manganese (Al-Mn) alloy series. To further improve its strength, an appropriate amount of magnesium (Mg) is added to the 3003 alloy composition. For this reason, it is also known as an aluminum-magnesium-manganese alloy.
As one of the most widely used anti-rust aluminum alloys, the key feature of 3004 aluminum sheet is that it is non-heat-treatable. This means its strength cannot be increased through heating and quenching; instead, its mechanical properties are improved primarily through cold working processes such as rolling.
Within the 3xxx alloy family, 3004 aluminum sheet is positioned as a medium-to-high-end material. Its strength is significantly higher than that of 1100 pure aluminum and the earlier 3003 aluminum alloy, while retaining the excellent corrosion resistance and workability of 3xxx series alloys.
