Vacuum brazing is a critical manufacturing process for producing high-performance tungsten steel saw blades where tungsten carbide tips are permanently bonded to a steel blade body. This technology ensures exceptional cutting accuracy wear resistance and long service life for demanding industrial cutting applications. 

In vacuum furnace brazing the blade body and carbide tips are heated in an oxygen-free environment which prevents oxidation and contamination. The brazing alloy melts and flows uniformly through capillary action creating clean void-free and high-strength joints with minimal thermal distortion. This results in precise tip positioning and consistent bonding quality across the entire blade.The final vacuum-brazed tungsten steel saw blade delivers superior hardness excellent heat dissipation and stable cutting performance even under high-speed and high-load conditions.
