Product Description
Sealmet HC-4 Alloy426
Description
A nickel-chromium-iron which has been developed to match the thermal expansion characteristics of 0120 glass. An additional advantage of this alloy for glass-to-metals seals is the tight dark green oxide coating formed by wet hydrogen annealing at 1900/2200°F (1038/1204°C) for one hour. The oxide tends to flux with the glass and make it a vacuum tight seal if the surfaces are clean. To obtain the necessary surface cleanliness, pickle in muriatic acid.
Applications
Glass to metal seals for a variety of electronic tubes and CRT tubes. It is supplied in wire form for compression seals.
