Overview alloy
Invar 42 is a Nickel-iron alloy used for sealing glass and metal. The coefficient of expansion of this alloy most closely match 1075 glass, but it is also used in seals for points. It can also be used with hard lenses if you use the slim-fitting tubular seal. For seals that were not hardened with hydrogen to the sealing, to facilitate bezhanovich the characteristics of the seal use a modification of this alloy that contains small additions of titanium. Used for glass-metal seals in electronic tubes, automotive and industrial lamps, transformer and capacitor bushings and other products where the combination of «glass-metal» and «ceramic-metal». Alloy included in the composition of the bimetallic coatings.
