Kovar was invented to meet the need for a reliable glass-to-metal seal that is required in electronic devices such as light bulbs, vacuum tubes, cathode ray tubes, and in vacuum systems in chemistry and other scientific research. Most metals cannot seal against glass because their coefficient of thermal expansion does not match that of glass. When the joint cools down after manufacture, the stresses caused by the different expansion rates of glass and metal cause the joint to tear.

Areas of application:

  • Stainless steel construction
  • Railing construction
  • nickel
  • Beverage industry
  • chemistry
  • Tank construction
