An investigation of factors influencing the mechanical strength of glass-to-metal seals

The mechanical strength of two widely used types of glass-to-metal seals, 29/17/54 nickel-cobalt iron alloy with borosilicate glass and 50/50 nickel-iron alloy with lead glass, have been examined. Controlled variations were made in the Oxidation treatment of the alloy component prior to sealing and...
