· JVASP-139135· NaAlF2

Sodium aluminum fluoride (NaAlF₂) is an inorganic ionic compound belonging to the fluoride salt family, commonly encountered as a byproduct or intermediate in aluminum processing and electrochemistry. It is primarily used in the aluminum smelting industry as a flux and electrolyte additive in Hall-Héroult cells, where it lowers the melting point of cryolite-based bath systems and improves electrical conductivity. The compound is valued in molten salt applications and specialized ceramics due to its chemical stability at elevated temperatures and its role in refining aluminum metal quality; engineers select it when thermal stability, ionic conductivity, and corrosion resistance in alkaline fluoride environments are critical.

Export Control

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
