What is Aluminum Foil?
The aluminum foil is an AL-Mn series alloy.It is a rust-proof aluminum foil with a wide range of applications, but it is not strong enough and cannot be strengthened by heat treatment. Therefore, the cold working method is adopted to improve its mechanical properties. It is necessary to have good forming performance, high corrosion resistance and good weldability for machining parts. The specific production process of aluminum foil is: melting casting-soaking-hot rolling-pre-annealing-cold rolling-intermediate annealing-cold rolling-foil rolling-slitting-performance testing-packaging. The produced aluminum foil has good formability, adhesion, and corrosion resistance. The aluminum foil produced is exported to many countries and regions around the world.

Key Features of Aluminum Foil
1.The Mn element is added to make the aluminum foil have antirust performance.
2.Good moldability, adhesion and corrosion resistance, it is an excellent material for manufacturing electronic foil.
3.Non-toxic and odorless, safe and hygienic. Aluminum foil is widely used as packaging material after compound, printing and gluing.
4. Aluminum is a recyclable metal, which can be processed after being scrapped and can be put back into use.
5.It also has excellent moisture-proof performance, light-shielding and extremely high barrier ability.

Applications of Aluminum Foil
As people’s demand for electronic products becomes more and more extensive, which promotes the rapid growth of the electronic information industry, emerging electronic products are emerging endlessly, so the demand for aluminum electrolytic capacitors is also increasing. The production bases of aluminum electrolytic capacitors in many countries are transferring to China, which promotes the rapid development of electronic foil processing industry in China. Therefore, as the raw material of electronic foil, aluminum foil will have a good market prospect. Due to the good formability of aluminum foil, it is also widely used in aviation meal boxes.. It can also be used as an aluminum honeycomb core.

Aluminum Foil Manufacturing processing
The whole aluminum production line start from the aluminum ingots, the aluminum block will be taken to the casting machine after melting in the melting equipment. After shaping the block to the thick plates, polishing in the special device, the aluminum thick plates are reheated in the furnace.
After hot rolling, cold rolling, the thick aluminum sheets will be tabletted into the smaller and thin pieces, the final procuts will be packed after the annealing.
