Powder Flux

Potassium tetrafluoroaluminate (01774)

potassium flux powder for non-corrosive aluminium brazing with Al-Si metal filler. Melting point onset <555°C, ultrafine particle size (D50) 5 - 10µm

Overview
Dry potassium flux powder with average particle size of 5 - 10µm for use as component in liquid flux preparations, e.g. in paint flux and flux pastes. The lower particle size leads to higher viscosities and slow settling suspension compared to potassium fluoroaluminate F (01740). Melting point onset <555°C for use with Al-Si alloys as filler.
