Materials introduction
Aluminum is a silvery white light metal. Ductility. The products are usually columnar, rod, flake, foil, powder, ribbon and filiform. A layer of oxide film to prevent metal corrosion can be formed in humid air. The acid treated aluminum powder heated in the air can burn violently and emit a dazzling white flame. Soluble in dilute sulfuric acid, dilute nitric acid, hydrochloric acid, sodium hydroxide and potassium hydroxide solution, insoluble in water, but can react with hot water slowly to produce aluminum hydroxide, the relative density of 2.70, elastic modulus 70Gpa, Poisson's ratio 0.33. Melting point 660. Boiling point 2327. It is widely used for its light, good conductivity and thermal conductivity, high reflectivity and oxidation resistance. Do the daily dish aluminum is usually called "steel" or "steel". The thermal expansion coefficient of Al at (25) Shi Wen is 0.0000236mm/ C or 23.6ppm*k-1.
