What Is 3003 H24 Heavy Duty Aluminum Foil?
3003 aluminum alloy belongs to the aluminum-manganese alloy series (Al-Mn). The addition of manganese, usually in the range of 1.0%–1.5%, is the key factor behind the excellent performance of 3003 alloy. Compared with pure aluminum, such as 1100 aluminum foil, 3003 aluminum alloy offers approximately 10% higher strength, while retaining the excellent rust resistance and thermal conductivity of aluminum.

1. Material Characteristics of 3003 Aluminum Alloy Foil
(1). Higher Strength Than Pure Aluminum Foil
The addition of manganese in 3003 aluminum alloy significantly improves its strength compared with 1xxx series pure aluminum. For products that require load-bearing capacity, stamping, bending or shape retention, 3003 aluminum foil provides better structural stability.
(2). Good Corrosion Resistance
3003 aluminum foil has excellent oxidation resistance and corrosion resistance. It is suitable for food packaging, container manufacturing, thermal insulation materials and composite materials used in humid environments.
(3). Excellent Formability
Although 3003 H24 aluminum foil has a certain level of hardness, it still maintains good ductility and processability. It is suitable for various secondary processing methods, including stamping, embossing, coating, laminating, compounding and slitting.
(4). Good Weldability and Processing Adaptability
3003 aluminum alloy has good weldability and is also suitable for mechanical processing and surface treatment. This makes it highly flexible for industrial manufacturing applications.
2. H24 Temper
The H24 temper means that the material has been strain-hardened and then partially annealed. This treatment allows the aluminum foil to achieve an ideal balance between strength and ductility.
This is one of the main reasons why 3003 H24 aluminum foil is widely used in aluminum foil lunch boxes, food containers, packaging trays and industrial structural materials.
3. Heavy Duty Aluminum Foil
"Heavy duty aluminum foil" generally refers to aluminum foil products with a thickness of 0.05 mm or above, and in some cases up to 0.2 mm or even thicker.
Compared with ordinary thin aluminum foil, heavy duty aluminum foil has higher mechanical strength, better rigidity and stronger resistance to deformation.

Storage and Transport
Storage: Store in a cool, dry, well-ventilated, and clean environment at a temperature of 5–30°C and a relative humidity of ≤55%. Avoid exposure to moisture, direct sunlight, and corrosive acids or alkalis. Rolls must be stored in an upright position to prevent deformation caused by compression.
Transport: Use moisture-proof packaging and protect against rain, impact, and scratches. Handle with care during loading and unloading to prevent the rolls from unraveling or sustaining surface damage.
