Aluminum is a metal element, the element symbol is al, and the atomic number is 13. Its elemental substance is a silvery white light metal. Malleable. Commodities are often made into rod, sheet, foil, powder, strip and filament. It can form an oxide film to prevent metal corrosion in humid air. When heated in air, aluminum powder can burn violently and emit dazzling white flame. It is easily soluble in dilute sulfuric acid, nitric acid, hydrochloric acid, sodium hydroxide and potassium hydroxide solutions, but difficult to dissolve in water. Relative density 2.70. Melting point 660 ℃. Boiling point 2327 ℃. Aluminum is the most abundant metal element in the earth's crust, ranking third only to oxygen and silicon. The development of aviation, construction and automobile industries requires the unique properties of aluminum and its alloys, which is greatly conducive to the production and application of this new metal aluminum. It is widely used.
Aluminum pipe is a kind of non-ferrous metal pipe, which refers to the metal tubular material that is extruded into a hollow along its longitudinal full length with pure aluminum or aluminum alloy.
Aluminum tube, or Aluminium pipe, can be delivered in a straight line, uniform cross-section or multiple through holes. Widely used in automobile, ship, aerospace, aviation, electrical appliances, agriculture, electromechanical, home and other industries.
