20mic Aluminium Foil is a very thin aluminum product that is commonly used as a packaging material, insulating material, and so on.
Manufacturing Process
The manufacturing process of 20 micron foil includes casting, rolling, annealing and slitting steps. The specific process is as follows:
Casting: ingots are melted and cast into aluminum plates or bars.
Rolling: Through multiple rolling, the plate is gradually rolled into the required thickness of aluminum foil.
Annealing: Anneal the rolled aluminum foil to improve its mechanical properties and flexibility.
Slitting: Slitting large rolls of aluminum foil into small rolls or sheets of the required size.

Precautions
The following points need to be noted when using aluminum foil:
Avoid contact with acidic and alkaline substances: these substances may react chemically with aluminum and cause corrosion of the foil.
Pay attention to safety when using at high temperatures: when aluminum foil is used at high temperatures (e.g. baking, barbecuing), avoid direct contact with open flames to prevent fire.
