Nickelbraze™ Filler Metals
Nickelbraze™ filler metals are used to join stainless steel, nickel and cobalt base alloys. They provide exceptional resistance to chemical corrosion and oxidation coupled with high strength at elevated temperatures. These alloys are widely used particularly within the aerospace, automotive and nuclear industries using vacuum or controlled atmosphere brazing methods. These products are available as pastes, powders or tapes. Several can be supplied in rapidly solidified foil form.
