A stop-off material comprising:
- a solvent;
- a thickener;
- and
- magnesium oxide, wherein 5 wt % to 60 wt % of the stop-off material comprises the magnesium oxide.
1 more element
A stop-off material comprising:
- a solvent;
- a thickener;
- and
- an amount of magnesium oxide such that the stop-off material is configured to be removed from a surface after heating and via air pressure.
1 more element
A method of brazing comprising:
- applying a stop-off material to a substrate to define a brazing area of the substrate, wherein the stop-off material comprises magnesium oxide;
- applying a brazing filler material to the brazing area of the substrate at a first temperature;
- heating the brazing filler material to a second temperature greater than the first temperature, wherein the second temperature is greater than a liquidus temperature of the brazing filler material;
- cooling the substrate and the brazing filler material to a third temperature lower than the second temperature;
- and
- removing the stop-off material from the substrate.
