Tenacity™ Products


Tenacity™ No. 6 contains an addition of elemental boron which improves filler metal wetting on refractory metals and difficult to wet materials such as tungsten carbide and PCD.

Variants, such as Tenacity™ No. 125 are also available which are suitable for bronze welding and components requiring extended heating cycles, low silver or copper-based brazing filler metals.
