Cutting Tools and Hard Metals
Ideal for brazing saw teeth and other cutting tool components, these alloys are specifically designed for brazing tungsten carbide to steel in cutting tools, compensating for internal stresses caused by the different coefficient of thermal expansion during cooling.
Why brazing alloys are used:
- To ensure reliable bonding between dissimilar materials (e.g., steel and hard metal).
- To compensate for thermal expansion differences between tool body and insert.
- To maintain mechanical integrity at high operating temperatures.
Recommended alloys:
- Silver-copper alloys with nickel (e.g., Ag-Cu-Ni-Zn): high mechanical properties, excellent thermal fatigue resistance.
- Trimetallic alloys (Ag/Cu/Ag) enable the brazing of hard metal while ensuring all required properties of sealing, mechanical strength, and impact resistance, thus meeting the specific requirements of the tool’s intended applications..
Why these alloys:
- Excellent adhesion to carbides and high-alloy steels.
- Even stress distribution minimizes the risk of cracking under load.
