NOCOLOK® Zn Flux - Markets & Applications

Brazing agent: 'Reactive' flux for brazing aluminium. During brazing, potassium fluoroaluminates (flux) are generated by the brazing agent in contact with Al / Si filler metal. In addition, zinc is produced and diffuses into the aluminium surface. Formation of a zinc-rich diffusion layer (corrosion protection).
