What Are the Advantages of Aluminum Pellets?

1. Introduction to the application of aluminum particles

Aluminum pellets are a kind of elemental aluminum with 99% aluminum content. It is made of aluminum blocks through repeated drawing and cutting, and the appearance is in the shape of a small cylinder. Aluminum wire can be made from aluminum pellets, and steel core aluminum can be made by adding iron elements. In industrial production, aluminum pellets are mainly used to finish processing various aluminum castings and zinc castings, and have a great effect on surface polishing, deburring and deburring. The surface of the aluminum castings after the treatment of aluminum particles is smooth and shiny, which makes the castings more beautiful. At the same time, aluminum particles can be mixed with stainless steel sand and stainless steel shots to achieve a whiter and brighter surface of the workpiece. The application range of aluminum particles is in aerospace, chemical industry, metallurgy, refractory materials, steel, furnace charge, ferroalloys, etc.

2. What are the advantages of aluminum pellets?

2.1 Low density. The density of aluminum particles is about 2.7 g/cm3. Its density is only 1/3 of that of iron or copper.

2.2 High plasticity. Aluminum pellets have good ductility and can be made into various products through pressure processing methods such as extrusion and stretching.

2.3 Corrosion resistance. Aluminum particles are a highly negatively charged metal. Under natural conditions or anodic oxidation, a protective oxide film will be formed on the surface, which has much better corrosion resistance than steel.

2.4 Aluminum particles have good electrical conductivity and are easy to recycle.

2.5 Easy to strengthen. The strength of pure aluminum particles is not high, but its strength can be improved after anodic oxidation.

2.6 Easy surface treatment. Surface treatment can further improve or change the surface properties of aluminum particles. The aluminum anodizing process is quite mature and stable in operation, so it has been widely used in the processing of aluminum products.
