What is the difference between aluminum and cast aluminum

One, the process method is different

1. Aluminum: Aluminum is silver-white light metal. There is malleability. Commodities are often made into columns, rods, sheets, foils, powders, ribbons and filaments. It can form an oxide film to prevent metal corrosion in humid air.

2. Cast aluminum: Cast aluminum is a process in which aluminum in a molten state is poured into a mold and cooled to form an aluminum part of the required shape.

Two, the preparation method is different

1. Aluminum: Mix bauxite, charcoal and table salt, pass in chlorine gas and heat to obtain NaCl, AlCl₃ double salt, and then melt this double salt with excess sodium to obtain metallic aluminum.

2. Cast aluminum: The vast majority of aluminum alloys no longer have a gas refining process in the melting furnace, but mainly rely on static furnace refining and online melt purification. Some aluminum processing plants still have a melting furnace for refining. The purpose is to improve the purity of the melt. These refining methods can be divided into two categories: gas refining and flux refining.
