Description

Technical Field

[0002] Aluminum tube is a kind of non-ferrous metal tube, which refers to a metal tubular material that is hollow along its entire longitudinal length by extrusion of pure aluminum or aluminum alloy. Aluminum is a metal element with the element symbol Al and the atomic number 13. Its single substance is a silvery-white light metal with ductility. The product is often made into rods, sheets, foils, powders, strips and wires, and can form an oxide film to prevent metal corrosion in humid air. Aluminum powder can burn violently when heated in air and emit a 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.
