Kovar Invar Alloy Strip Description
Alloy-4J29 (Expansion alloy)
(Common Name: Kovar, Nilo K, KV-1, Dilver Po, Vacon 12)OhmAlloy-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 and other scientific research. Most metals cannot seal to glass because their coefficient of thermal expansion is not the same as glass, so as the joint cools after fabrication the stresses due to the differential expansion rates of the glass and metal cause the joint to crack.

| Application: | 4J36 is a special low expansion iron-nickel alloy with ultra-low expansion coefficient. The control of carbon and manganese components is very important. Cold deformation can reduce the coefficient of thermal expansion, and heat treatment in a specific temperature range can stabilize the coefficient of thermal expansion. Low expansion alloy 4J36 has a low expansion coefficient and good plasticity within the atmospheric temperature variation of -60-80 degrees, which is used to make components with a size close to constant within the temperature variation range, widely used in radio, precision instrument, instrument and other industries, making standard measuring tools, microwave resonant cavity, bimetallic wave layer and other application scope: thermostat, 5G filter, OLED screen, LNG ship |
