Why is the aluminum plate not rusting?

The question is wrong, and the aluminum is also rusted, but the aluminum rust does not rust like iron until it is rusted.
The metal is oxidized by oxygen in the air and is rusted. Aluminum reacts with oxygen to form aluminum oxide, which is aluminum rust. Aluminium rust is very thin, its thickness is only one ten thousandth of a millimeter, but it is very hard and very wear-resistant. It is close to the surface of the aluminum, so that the aluminum inside is not exposed to the outside air, preventing the aluminum from continuing to rust.

Why is the aluminum plate non-ferrous metal?

Narrowly defined non-ferrous metals, also known as non-ferrous metals, are collectively referred to as all metals except iron, manganese, and chromium; generalized non-ferrous metals also include non-ferrous alloys (based on a non-ferrous metal (usually greater than 50%), with the addition of one or An alloy composed of several other elements).

Why is aluminum a fly metal?

The density of aluminum is small, only 2.7g/cm3, and there is a dense Al?O? film on the surface, which prevents the internal aluminum from reacting and is not easily oxidized. It is a commonly used material for aircraft. 70% of modern aircraft are made of aluminum and aluminum alloy, so it is called flying metal.

Why is aluminum trivalent?

Simply speaking, the outer electron arrangement of aluminum atoms is 2, 8, and 3.
The outermost electrons are not full, the structure is unstable, and the three electrons are easily lost. Therefore, the trivalent is often remarked, but it is obvious that the three electrons of the outermost layer of the electron and the outermost two electrons of the magnesium are stable, so Aluminum has no sodium or magnesium active.

Why are aluminum profiles generally surface treated?

If the aluminum profile is not surface treated, the appearance is not beautiful, and it is easy to be corroded in humid air. It is difficult to achieve the high decorative and strong weather resistance requirements of the aluminum profile in the building materials, in order to improve the decorative effect and enhance the corrosion resistance. And to extend the service life, aluminum profiles are generally surface treated.

Why is aluminum more expensive than iron?

Although aluminum has more reserves in the earth’s crust than iron, the production process of aluminum is much more complicated than iron. Aluminum is a relatively active metal element. The smelting needs to be done by electrolysis. The cost of the whole production process is higher than that of iron. , so the price of aluminum is higher than iron.

What are the uses of aluminum panels?

The use of aluminum plates is tens of millions, but in summary there are mainly the following major uses:
Aluminium sheeting Aerospace aluminum is used to make aircraft skins, fuselage frames, girders, rotors, propellers, mailboxes, siding and landing gear pillars, as well as rocket forging rings and spacecraft siding. Widely used in packaging of beverages, food, cosmetics, pharmaceuticals, cigarettes, industrial products, etc. Aluminum for transportation can provide all kinds of aluminum alloy materials for automobiles, and large-scale porous materials for subway and light rail to fill the domestic gap, and meet the requirements of the localization of subway for the manufacture of automobile, subway vehicles, railway passenger cars, and high-speed passenger cars. Parts, doors and windows and shelves, automotive engine parts, air conditioners, radiators, body panels, wheels and ships. Packaging aluminum all-aluminum cans are a measure of the level of aluminum processing in a country.
Aluminum is mainly used as a metal packaging material in the form of thin plates and foils, and is made into cans, lids, bottles, barrels, and packaging foils. Printing aluminum, the printing industry bid farewell to “lead and fire”, stepping into the era of “light and electricity”. Aluminum-based PS board provides strong support for this revolution in the printing industry. Aluminum for electronic home appliances is mainly used in various busbars, wires, conductors, electrical components, refrigerators, cables and other fields. Aluminum for building decoration: Aluminum alloy is widely used in building structures, doors and windows, ceilings, decorative surfaces, etc. due to its good corrosion resistance, sufficient strength, excellent process performance and welding performance.
