Höganäs BrazeLet® pastes
A brazing paste is a homogeneous mixture of the brazing filler metal powder (about 80-90wt.-%) and water or oil based flux-free binder. The binders are removed in the furnace during brazing. The formulation is adapted according to factors like furnace conditions and the paste application method. Höganäs binders are developed to minimize polymer content and allow higher metal content in the pastes. This allows for more brazed joints per kilogram of paste and reduces the impact on the furnace and on the brazing quality of the parts.
The rheological behavior of the brazing paste is designed to suit the different application methods. In general, thin layer application methods like roller coating, thin printing or spraying require more liquid formulations, whereas dispensing or thick layer printing requires a higher viscosity.
Höganäs offers customized brazing pastes as well as several types of paste packaging; syringes, various sizes of cartridges, cans and larger buckets are available.
