Description
Features
- Corrosion Resistance
3003 aluminum foil has excellent resistance to atmospheric corrosion, especially in outdoor and marine environments, making it suitable for various weather conditions.
- Good Formability
This alloy can be easily shaped or formed into different sizes and designs, allowing it to be used in flexible packaging, insulation, and other applications that require malleability.
- Strength
While it is not as strong as other alloys like 6061, 3003 offers a good strength-to-weight ratio for many applications. It’s stronger than pure aluminum (1070).
- Weldability
3003 is known for its good weldability, making it an excellent choice for applications that require joining with other materials.
- Printable
Its surface can be printed on, making it suitable for customized packaging and labeling.
Common Applications
- Food Packaging
3003 aluminum foil is commonly used in food packaging, as it protects food from moisture, light, and contaminants. It’s used in wrapping, cooking, and storage.
- Insulation
Due to its reflective properties, 3003 aluminum foil is widely used in insulation applications, especially in buildings and refrigeration.
- Pharmaceutical Packaging
Like other aluminum foils, it is used for blister packaging to protect pharmaceuticals from moisture and air.
- Electrical
3003 is used for cable shields and insulation materials due to its electrical conductivity.
- Heat Exchangers
The alloy is suitable for use in heat exchangers because of its thermal conductivity and corrosion resistance.
