Some information about aluminum

1. Aluminum is a metal element, the element symbol is Al, the atomic number is 13, and its elemental substance is silver-white light metal. This is accusable. Commodities are usually in the form of sticks, sheets, foils, powders, bars, and filament. In humid air, an oxide film can be formed to prevent metal corrosion. When heated in the air, the aluminum powder burns violently, emitting a dazzling white flame. Soluble in nitric acid, hydrochloric acid, sodium hydroxide, potassium hydroxide solution, difficult to dissolve in water. The relative density is 2.70. The melting point is 660 °c. The boiling point is 2327 °c. Aluminum is the most abundant metallic element in the earth's crust after oxygen and silicon. The development of the aviation, construction and automotive industries requires the unique properties of aluminum and its alloys, which greatly facilitates the production and application of this new type of aluminum metal. It is widely used.

2. Aluminum alloy is based on aluminum, and a certain amount of other alloying elements are added. It is a light metal material. Aluminum-based alloys containing some other alloying elements are one of the light metal materials. Aluminum alloy except

How much is scrap aluminum, a pound of scrap aluminum recycling price is about 10 yuan per kilogram. The recycling price of scrap aluminum is about 10 yuan per kilogram, and the price of scrap aluminum is different depending on the type. The scrap aluminum that is often recycled is, scrap aluminum line, scrap aluminum tube, scrap aluminum row, scrap aluminum pin, scrap aluminum alloy, scrap aluminum rod, aluminum profile recycling, the price of these scrap aluminum is not the same. Primary classification and grading stacking of scrap aluminum, such as pure aluminum, deformed aluminum alloy, cast aluminum alloy, mixture, etc. The import volume of aluminum scrap accounts for more than one-tenth of the country's total imports.
