The main grades commonly used in 3 series aluminum alloys are 3003 Aluminum Foil and 3004 Aluminum Foil, of which 3003 aluminum alloy is the most used. 3003 aluminum foil is easy to process and has good anti-rust performance. Color paint can be painted on the surface of the original aluminum to make various styles of aluminum foil lunch boxes. Lightweight and durable, beautiful style, fast and convenient.
The 3 series aluminum alloy is also called aluminum-manganese alloy. The manganese content is 1-1.5%. It is a widely used anti-rust aluminum alloy series. The strength of 3 series aluminum alloy is higher than that of pure aluminum alloy. Although the performance cannot be strengthened by heat treatment, it has good plasticity after cold working (cold rolling) and annealing process. Due to its good corrosion resistance and welding performance, it can be used in packaging industry, building decoration industry, electronic manufacturing industry and many other industries. Automobile manufacturing, etc.
3003 aluminum foil roll is a widely used metal material with very good flexibility and ductility. Whether it is in industrial manufacturing or food production, it has an irreplaceable important position. Packaging aluminum foil is the main growth point of the aluminum foil consumer market. In recent years, with the development of the packaging industry, the consumption of the aluminum foil industry has continued to rise, coupled with the low-carbon economy and the improvement of people's living standards, the demand for aluminum foil food will increase significantly in the next few years, which will bring about New business opportunities.
Aluminum Foil rolls food grade with other materials expands its application market. When using aluminum foil, it is usually combined with materials such as paper and plastic. In this way, the shielding performance of aluminum foil is combined with the strength of paper and the heat-sealability of plastic. Enhance the shielding performance of packaging materials against water vapor, air, ultraviolet rays and bacteria, and greatly expand the application market of aluminum foil.
