Potassium Cryolite
Potassium aluminum fluoride (K3AlF6) used as a brazing flux for aluminum and aluminum alloys, and as an active filler in grinding wheels. Lower melting point than sodium cryolite makes it ideal for low-temperature aluminum joining.
// Key Features
- Lower melting point than Na3AlF6
- Excellent aluminum brazing flux
- Effective grinding aid
- Free-flowing fine powder
