Want to melt the cans into aluminium ingots, but what about iron cans?
Silver light metal. Ductility. Goods are often made in bars, sheets, foils, powders, ribbons, and filaments. A layer of oxide film that prevents metal corrosion is formed in moist air. Aluminum powder and aluminum foil heated in the air can burn violently and give a dazzling white flame. Soluble in dilute sulfuric acid, nitric acid, hydrochloric acid, sodium hydroxide and potassium hydroxide solution, insoluble in water. Relative density 2.70. Melting point 660 DEG C. Boiling point 2327 DEG C.
A magnetic drum is used to absorb iron, and then iron is removed.
Aluminum is the third largest in the earth's crust, second only to oxygen and silicon, and is the most abundant metal element in the earth's crust. The development of the three important industries, aviation, architecture and automobile, requires that the material characteristics have the unique properties of aluminum and its alloys, which will greatly benefit the production and application of the new metal aluminum. Applications are very extensive.
