Detail Specifications / Descriptions
Features:
1. Both Cad-free and Cad bearing alloys can be used.
2. Silver alloys with Nickel or Manganese can solve the difficulty of brazing on carbides.
3. Silver alloy has the characteristics of low melting point and good fluid, which can apply to weld on the small Tungsten carbides - Silver containment of 35%,42%,45%,50%,56%.
4. Nickel and manganese containing alloys for thicker joints on medium sized
carbides.
5. Tri-foil products with nickel & manganese containing for brazing large
carbides as Cl-4900L.
6. Tri-foil alloys can help the internal stresses arise due to the different coefficient of expansion, which exists between the tungsten carbide and the base material.
