HT-55
HT-55 is primarily used in joining carbide components to steel holders. The improved gap filling capabilities and ductility of HT-55 make it a suitable alloy for this application.
Available Forms
Strip, engineered preforms, specialty preforms, powder and paste
Characteristics
HT-55 can be brazed by a variety of different processes including induction and atmospheric furnace brazing. It exhibits excellent gap filling capabilities and plasticity in the molten state. It is important to ensure that the base components are properly cleaned prior to the application of the braze alloy. *The mechanical properties listed above were determined from lap joints of tungsten carbide and SAE 8740 steel tested at ambient temperatures.
Properties
HT-55 exhibits improved strength and ductility at elevated temperatures compared to other nickel silvers. This is beneficial for minimizing any distortion caused from a mismatch in thermal expansion coefficients of the base metals.
