Aluminum foil is made of aluminum alloy which purity is 92% to 99%. Typically, the thickness is between 0.0043 and 0.2 mm, the width and strength of aluminium foil can meet various applications. It is used for manufacturing thermal insulation materials in construction industry, coils of transformer, fins of air conditioner, capacitors of radio and television, decorative products, thermal insulation materials of storage tank, containers and packaging. 

Aluminum foil has several main advantages, the most important of which is the abundance of raw materials required for its manufacture. Aluminum foil is durable, cheap, non-toxic and oil resistant. In addition, it can resist chemical attack and provide good electrical and non-magnetic shielding.
