Silver Brazing pastes for carbide tungsten
Cadmium free Silver alloys are appreciated for excellent mechanical properties and bear good wetting characteristics. These are preferably used for brazing hard metals to steel mountings. Addition of nickel and manganese improves wettability on tungsten and molybdenum materials. Joint-brazing at working temperatures of max. 200 C without loss in strength. The above list is a standard range of our regular production, for any special request please do not hesitate to contact us directly or through our consultants.
Heat sources: acetylene torch, induction and resistance heating, vacuum furnace
