Ultra Black Flux is a boron modified, water based active fluoride/borate-type flux in paste form, which has been specially formulated to give excellent adhesion when dipped or brushed on parts. It is recommended to use with filler metals that flow between 1050°F - 1800°F and specifically formulated to ensure a creamy consistency. The flux provides excellent protection of parts up to 1800°F . Ultra Black Flux is primarily used as a general purpose brazing flux in brazing applications involving brazing of steel, stainless steel, copper, copper alloys, nickel, and nickel alloys. It is not recommended to use in aluminum bronze or other aluminum alloy brazing applications. Ultra Black Flux is suitable for use with most heating methods including torch, induction or furnace. This product exhibits excellent adhesion, oxide absorbing capabilities, and less spattering during the brazing process.Information provided by Lucas-Milhaupt. |
