What is 3004 foil? 3004 aluminum alloy foil is an aluminum alloy mainly composed of aluminum, manganese and magnesium (AL-Mn alloy foil). Aluminum 3004 belongs to the 3000 series aluminum alloy, which is famous for its excellent corrosion resistance, good formability and medium strength, and its strength is higher than 3003 aluminum foil alloy.
3004 aluminum foil has a high magnesium and manganese content and has excellent anti-rust properties, also known as anti-rust alloy. It can also be used well in some places with relatively high humidity.
What are the advantages of choosing aluminum foil 3004 for food containers or lunch boxes? 3004 aluminum foil is a popular choice for food containers and lunch box lining materials due to its excellent barrier, formability, and corrosion resistance. 3004 aluminum alloy is slightly stronger than 1000 series 1100 or 1145 soft aluminum foil, so it has better durability in applications where puncture resistance and longer product shelf life are important.
Advantages of 3004 aluminum foil on food packaging and containers:
Non-toxic and odorless: 3004 aluminum foil is food grade and meets safety standards for direct contact with food. 3004 aluminum foil does not impart any toxic chemicals or metallic taste/odor to the packaged items.
Moisture barrier: 3004 aluminum foil has excellent moisture barrier properties to prevent moisture and oxidation. This helps prevent moisture transfer or increase, thus keeping food fresh.
Strong barrier properties: 3004 container aluminum foil also acts as an effective grease barrier material and can be used to package and line oily foods. It prevents leaks and staining problems.
Good light blocking properties: 3004 aluminum foil blocks UV exposure, helping to preserve nutritional value and prevent spoilage by blocking wavelengths that can cause food to decompose.
Excellent formability: 3004 aluminum alloy has good formability, and the foil can be embossed or formed with close tolerances. It can be formed into trays, container bodies, lids, and other shapes.
The characteristics of 3004 aluminum foil are determined by its chemical composition and manufacturing process, which also allows 3004 aluminum alloy foil to have better applications.
Some notable properties of Aluminum 3004 foil include:
3004 aluminum foil has excellent corrosion resistance, especially in environments exposed to moisture and air. Al 3004 foil is able to form a protective oxide layer to prevent further degradation.
Aluminum foil 3004 alloy has high thermal conductivity, making it an excellent choice for applications that require efficient heat dissipation or insulation.
The alloy has high ductility, allowing it to be rolled into thin sheets and foils without compromising its structural integrity.
3004 aluminum foil is safe for food and pharmaceutical applications. In addition, aluminum alloy foil is 100% recyclable, making it an environmentally friendly choice.
3003 vs 3004 aluminum foil
What is the difference between 3003 and 3004 aluminum? Strength: 3004 is slightly stronger due to the higher magnesium content. Corrosion Resistance: Both alloys offer excellent corrosion resistance, but 3004 may have a slight edge in certain environments. Applications: 3003 is more commonly used for basic packaging, while 3004 is better suited for demanding industrial applications such as construction and automotive.
3104 vs. 3004 Aluminum Foil
Mechanical Strength: 3104 has slightly higher tensile strength and is suitable for applications that require greater load-bearing capacity. Ductility: 3004 is better formable in thin foil.
