Aluminium Fluoride: Spec.: F: 60% min Al: 30% min Na: 0.5% max SiO2: 0.5% max Fe2O3: 0.1% max H2O (5500C,1h): 0.5% max Packing: 25/1000kg plastic woven bags with film lining. Application: It is mainly used to adjust the molecular ratio in aluminium electrolyzing bath as a flux. The anhydrous AlF3 can reduce environmental pollution, improve the production yield of aluminium smelters and lower electrolytic cost.
