High Coefficient Kovar Alloy Rods Of Thermal Expansion UNS K94610

High Coefficient Of Thermal Expansion Kovar Alloy Rods UNS K94610

Kovar Alloy Rods is also called sealing alloy or constant expansion alloy. Alloy with relatively constant low or medium expansion coefficient in the temperature range of - 70 to 500 ℃. It is close to the expansion coefficient of sealed materials such as glass or ceramics, so as to achieve the effect of matching sealing. The main types are iron nickel, iron nickel cobalt, iron nickel chromium alloys. There are also oxygen free copper, tungsten, molybdenum and their alloys and composites. It is mainly used as sealing material in electronic industry and electric vacuum industry.
