Paste
High silver alloy with low working temperature and high mechanical resistance. It is the most widely used alloy in the tungsten carbide tool industry.
The high content of Manganese makes it possible to use it even in the case of tools made of carbides containing titanium or Tantal.
Highly appreciated for the mechanical seal of the joint at the end of the welding.
If used in the induction welding of the tools, we recommend the use of deoxidizing paste F9. For all other applications the use of F4 deoxidizing paste is recommended.
