Purification of aluminum profiles refers to the process of removing impurities from aluminum alloys to improve the quality and performance of the material. The process of purification can be accomplished through various methods, including casting and smelting, electrolytic refining, and vacuum induction refining.
Casting and smelting is a process where impure aluminum is melted and cast into ingots, which are then remelted and refined to remove impurities.
Electrolytic refining involves dissolving the impure aluminum in an electrolytic bath and passing an electrical current through the solution, which causes the impurities to be deposited on the cathode and the pure aluminum to be deposited on the anode.
Vacuum induction refining involves melting the impure aluminum in a vacuum induction furnace and using a combination of heat and a vacuum to remove impurities.
Regardless of the method used, the goal of purifying
aluminum profiles is to produce a material with improved physical and chemical properties, increased corrosion resistance, and improved performance in various applications.
