Meta-Braze™ Copper Based Brazing Alloys

These copper based filler metals are a range of special products designed for high temperature brazing of steel and carbide components. The Meta-Braze™ Cu products which contain nickel and or manganese can show improved wetting on tungsten carbide. Copper can be used as a filler metal in its own right. It can be supplied in a variety of forms and is used for aerospace, automotive and electronic applications.
