Industrial Grade Aluminum Fluoride CAS 7784-18-1 for Aluminum Electrolysis

Aluminum Fluoride (AlF₃, CAS:7784-18-1,EINECS:232-051-1, HS Code:2826120000, MW:83.98) is a white crystalline powder or granular solid primarily produced via advanced dry process (reaction of anhydrous hydrogen fluoride with aluminum hydroxide) followed by high-temperature calcination. Our industrial grade anhydrous aluminum fluoride features ≥99.0% minimum purity with strictly controlled silica and iron impurities, complying with GB/T 4292-2017 and international aluminum industry standards. It exhibits high thermal stability, low volatility and excellent fluxing properties, significantly reducing the melting point of alumina and improving electrolyte conductivity in aluminum electrolysis. As the most critical auxiliary material for primary aluminum production, it accounts for over 90% of global aluminum fluoride consumption.
