Studies on the Weldability of Dental Metallic Material

Objective: To elevate the weldability of usuallyused dental metallic materials such as Co-Cr alloy and 1Cr18Ni9Ti stainless steel,the weldability of five brazings were studied.Methods: The brazings of the best brazing properties were selected by means of moistness test,filling-seam test,mechanical-property test and micro-structural analysis.Results: No.1 and No.4 brazings had excellent comprehensive properties and weldability.Conclusion: No.1 and No.4 brazings can substitute for the silver-based brazings which is imported from America and expensive.
