Carbide Tip Tool Production
High Silver Strip is used for brazing carbide and diamond tools to steel and available in rods, wires and strips, Safety-Silv® high silver strip has a low brazing temperature, good fluidity, wettability and high tensile strength. Because Harris utilizes only pure base metals, you can expect consistency in product quality, composition, chemistry, dimensions and performance.
High silver trimetal (also referred to as Trimet) strip is designed to absorb the vibration when a tool is in operation which reduces the occurrence of cracks in the carbide segments. Harris® high silver trimetal strip has similar chemical composition to Safety-Silv® 49M, so it has a low brazing temperature, good fluidity, wettability and high tensile strength. However, it has an intermediate copper layer between two high silver layers. The addition of the copper layer reduces the residual cooling tensile caused by the different expansion rates between the base metal (usually steel) and the segments (usually tungsten carbide). Harris High Silver Trimetal Strip packaging is specially designed for automatic continuous brazing.
