Products are often made into sticks, sheets, foils, powders, ribbons and filaments.

An oxide film that prevents metal corrosion from forming in damp air.

The aluminum powder adds heat to the air and burns it in a blinding white flame.

Soluble in dilute sulfuric acid, nitric acid, hydrochloric acid, sodium hydroxide and potassium hydroxide solution, difficult to dissolve in water.

Relative density 2.70.

Melting point is 660 ℃.

The boiling point of 2327 ℃.

Aluminium is the third most abundant element in the earth's crust, after oxygen and silicon.

The development of three major industries, aviation, architecture and automobile, requires the unique properties of aluminum and its alloys, which is greatly beneficial to the production and application of this new aluminum.

The application is very extensive.
