Will aluminum alloy rust?
Aluminum alloy will rust. Although aluminum alloy has a good anti-rust effect, because aluminum alloy is also a metal material, it will also rust. However, after the aluminum in the aluminum alloy is oxidized, a dense aluminum oxide "protective film" is formed, which can prevent further oxidation of aluminum. Its anti-corrosion performance is mainly attributed to the oxide film coating on the surface that isolates it from contact with external air and water vapor, avoiding chemical reactions between each other and thus preventing corrosion.
An alloy based on aluminum with a certain amount of other alloying elements added is one of the light metal materials. In addition to the general properties of aluminum, aluminum alloys also have some specific properties of alloys due to the different types and quantities of added alloying elements.
The density of aluminum alloy is 2.63~2.85g/cm. It has high strength, the specific strength is close to high alloy steel, and the specific stiffness exceeds steel. It has good casting performance and plastic processing performance, good electrical and thermal conductivity, and good resistance to Corrosion-resistant and weldable, it can be used as structural materials.
Aluminum alloys are divided into deformed aluminum alloys and cast aluminum alloys according to their composition and processing methods. Deformed aluminum alloy is made by first melting and casting the alloy ingredients into ingots, and then plastically deforming them. Various plastically processed products are made through rolling, extrusion, stretching, forging and other methods.
In the early days of aluminum alloy research and development, it was mainly associated with the aviation industry. It has only a history of nearly a hundred years, but it has developed rapidly and its range of uses continues to expand. Among metal materials, its output ranks second after steel, and ranks second among non-ferrous metal materials. Among metal materials, it ranks first.
Aluminum alloy has the characteristics of low density, good mechanical properties, good processing performance, non-toxic, easy to recycle, excellent electrical conductivity, heat transfer and corrosion resistance. It is widely used in the marine industry, chemical industry, aerospace, metal packaging, transportation, etc. widely used in the field.
