POWDERS AND PASTES

A wide range of filler metals in powder and paste is available.
Brazing is performed in air, under protective atmosphere, or in vacuum, by flame, induction or in furnace.
Powders are available in different grain sizes, from coarse to fine.
Pastes can be supplied with and without flux, with various binders and with different metal content percentages, in order to
fulfill the most demanding applications.
To select the most appropriate brazing paste, many factors have to be taken into account, such as: type and dimensions of
pieces, materials to be joined, heating method, type of atmosphere, etc.
Consequently technical testing is generally required to select the most appropriate paste for the specific customer application.
