Kovar Powder (Iron-nickel-cobalt) Description
Kovar Powder (Iron-nickel-cobalt) is an Iron-nickel-cobalt alloy with excellent structural stability at a wide range of temperatures. It has a high Curie point. The oxide film of the Kovar Powder is dense and can be well-wetted by the glass. It does not interact with mercury, so it is suitable for instruments containing mercury discharge. It is utilized as the main sealing structure material of electric vacuum devices and is widely used in aircraft and power-generation turbines, rocket engines, nuclear power, and chemical processing plants.
