Abstract
Flexible metal tapes and adhesives are disclosed. The tapes comprise one or more alloy powders, PTFE powder, and a water-based casting vehicle, while the adhesives include inorganic substances such as sodium silicate, boric acid, sodium tetraborate, sodium fluoride, or sodium aluminum fluoride as well as pastes having compositions similar to the flexible metal tapes. The tapes and adhesives shrink minimally linearly when brazed to metal substrates, avoiding surface cracks that often result from shrinkage. The adhesive additionally retains the tape in place on the substrate, regardless of orientation, both before and during brazing.
