TANKII ALLOY-4J29 also known as Kovar alloy. it was invented to meet the need for a reliable glass-to-metal seal, which is required in electronic devices such as light bulbs, vacuum tubes, cathode ray tubes, and in vacuum systems in chemistry
Kovar alloy is a vacuum melted, iron-nickel-cobalt, low expansion alloy whose chemical composition is controlled within narrow limits to assure precise uniform thermal expansion properties. Extensive quality controls are employed in the manufacture of this alloy to ensure uniform physical and mechanical properties for ease in deep drawing, stamping and machining. What is kovar alloy? LKALLOYMar 21, 2020 · KOVAR alloy is an Iron-Nickel-Cobalt alloy with a density of 8.36g/cm3 and a linear expansion coefficient between 20 and 500 equal to that of glass and ceramics. Most metals cannot be sealed with glass because their thermal expansion rate is different from that of glass and the joints are liable to break when cooled. kovar alloy sheet, kovar alloy sheet Suppliers and UNS K94610 Kovar iron-nickel-cobalt alloy sheet Kovar is an iron-nickel-cobalt alloy with a coefficient of thermal expansion similar to that of hard (borosilicate) glass. This makes it especially suitable for uses which require a matched-expansion seal between metal and glass parts.
