Powder Flux

Potassium tetrafluoroaluminate (01732)

potassium flux powder for non-corrosive aluminium brazing with Al-Si metal filler. Melting point onset <555°C, medium particle size (D50) 10 - 15µm

Overview
Dry potassium flux powder with average particle size of 10 - 15µm for use as component in liquid flux preparations, e.g. in paint flux and flux pastes. The higher particle size leads to lower viscosities compared to potassium fluoroaluminate F (01740). Melting point onset <555°C for use with Al-Si alloys as filler.
