What are the factors affecting the service life of industrial aluminum profiles
Industrial aluminum profiles are alloy materials with aluminum as the main component. The aluminum rods are melted and extruded to obtain aluminum materials with different cross-sections. However, the mechanical properties and application fields of the industrial aluminum profiles produced are also different depending on the proportion of the added alloy.
As one of the main varieties of aluminum profiles, industrial profiles are widely used in machinery, transportation, electronics, petroleum, light industry, chemical industry, aviation and other fields. Because it has the advantages of one extrusion molding, high mechanical and physical properties, good thermal conductivity and high specific strength.
What are the factors that affect the service life of industrial aluminum profiles?
1. Whether to carry out surface treatment
Generally speaking, industrial aluminum profiles with artificial surface treatment have a longer service life. Even without artificial surface treatment, the oxide film will form naturally. The difference is that the artificial oxide film formed by surface treatment is thicker, more uniform and denser than the naturally formed oxide film, which can block the air well and is more wear-resistant than the oxide film formed in the natural air.
2. Different use environments
There is no doubt that the service life of industrial aluminum profiles in different usage scenarios is also quite different. Some special industrial aluminum profiles will be used in water or more corrosive environments.
In this case, in order to prolong its service life, aluminum profiles generally increase the anodizing time, increase the thickness of the oxide film, or perform hard oxidation on the surface. The service life of aluminum profiles in outdoor environments is different from that used in indoor places.
3. Alloy content
It is reported that there are also examples in the market of reducing the alloy content of industrial aluminum profiles in order to reduce costs, so that the service life of the produced profiles will be affected. Specifically, the quality and alloy content of industrial aluminum profiles are not enough, or too many other impurities are mixed in the aluminum profiles, which may greatly shorten their service life.
Especially iron, if the industrial aluminum profile contains a certain amount of iron, it will greatly reduce its corrosion resistance. Be sure to pay attention to this when purchasing. Some factories use scrap aluminum, and the surface of the reprocessed aluminum turns black, indicating that the iron content exceeds the standard and everyone should be cautious.
