Aluminium-metallurgy:
- as component in fluxing and grain refining agents
for aluminium and magnesium
- as component in protecting salts for light metal castings
Production of abrasives:
- as active filler in reinbonded abrasives for metal treatment
Production of soldering agents:
- as component in fluxing agents for soldering and brazing
According to one aspect of the invention, a braze composition is provided that
comprises an aqueous binder system, a flux composition containing multiple
inorganic compounds, and titanium hydride. The multiple inorganic compounds
include potassium tetrafluoroaluminate and/or potassium tetrafluoroborate, more
preferably both. The flux composition may contain additional inorganic compounds
that, while optional, if used can be preferably selected to have a decomposition
temperature or to form an intermediate complex having a decomposition
temperature that is above or below the decomposition temperatures of potassium
tetrafluoroaluminate and potassium tetrafluoroborate. According to a preferred
aspect of the invention, the braze composition further contains a metallic braze
alloy and is in the form of a braze paste or slurry suitable for use in manufacturing,
coating, repair, and build-up of superalloy components
