Aluminum Fluoride (CAS 7784-18-1) is a white, odorless inorganic compound supplied as a fine powder or granule, and it is used in aluminium smelting as a flux that lowers melting temperature and energy consumption, as well as in ceramics, glass and specialty chemical production. It is widely used in metallurgical and chemical processes due to its ability to modify melting behaviour and improve process efficiency. The product is valued for its high purity, stable composition and consistent performance in large scale operations.
