What is Aluminum Foil?
Aluminum (Al) is a silvery white, soft, ductile metal that is the third most abundant element (after oxygen and silicon) and makes up about 8% by weight of the Earth’s crust. Aluminum is so chemically reactive that native specimens are rare. Instead, it is found combined in over 270 different minerals. The primary ore used in the production of aluminum metal is bauxite.
Aluminum is remarkable for its light weight, strength, durability and for its ability to resist corrosion, due to the formation of an extremely thin yet very strong layer of oxide film. Structural components made from aluminum and its alloys are vital to the aerospace industry, transportation, building construction, and many other industries and applications.
Aluminum foil is widely used in packaging, insulation, and electromagnetic shielding. Aluminum sheet is used to manufacture vehicle bodies, home appliances, siding, cookware, and in thousands of industrial applications where a strong, light, easily formed material is needed.
Why choose aluminum foil as roof waterproof material?
Aluminium foil can provide complete insulation to light, oxygen, moisture and bacteria making。
Because of these characteristics, aluminum foil is now an excellent and irreplaceable waterproof material for aluminum foil.
