KOVAR (UNS K94610) (4J29)

Super alloys are built to function well in high temperature applications. Some of the components that use super alloys include gas turbine engines, rocket motors, nuclear reactors, submarines, and petroleum equipment.
Super alloy KOVAR is an iron-based alloy with nickel and cobalt. The chemical composition is well controlled so as to provide low, uniform, thermal expansion property for this alloy.
