Kovar 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 and other scientific research.

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.

2016年10月23日 · Kovar is an iron nickel cobalt alloy with a coefficient of thermal expansion similar to that of hard glass. This might make sense to those of a more engineering technical mind but in layman’s terms what does this actually mean and what is it used for?

KOVAR is a Virginia Knights of Columbus 501(c) (3) tax exempt charity established in 1971 to empower nonprofit organizations with financial support to improve access to affordable housing, job training, sports participation, and personal care for Virginians with Intellectual Disabilities.

Kovar® is an alloy made up of 29% nickel, 17% cobalt, .2% silicon, .3% manganese and 53.5% iron. Kovar® is known for its low coefficient of thermal expansion. Kovar is suitable for uses which require a matched expansion seal between metal and glass parts.

Kovar 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.

2024年7月29日 · Explore Kovar metal, manufactured for glass-to-metal seals in aerospace, electronics, and science. Discover Kovar's advantages, metal spinning, and forming techniques.

Kovar is popular for hermetic seals and used for making metal to glass or metal to ceramic seals. Kovar is also used in the medical, scientific, and research communities as well as in transformers, diodes, conductors, and transducers for its low coefficient of thermal expansion.
