KOVAR is a superalloy of the Iron-Nickel combination consisting of higher Nickel and Cobalt content of nearly 29 and 17 of percentage. In addition, it includes the fair value of Silicon, Chromium, and Carbon added to Iron. The alloy offers excellent thermal properties with a lower thermal coefficient value.
It is preferred for qualities like:
KOVAR ROD is excellent thermal performing with low expansion. It shows higher mechanical properties at elevated temperatures due to the higher melting temperature of the material. It is featured with the controlled alloy formation to obtain the precise thermal coefficient of expansion close to glass properties. Thus these rods are obtained with exceptional hardness properties. These rods are excellently formed with higher ductility in various shapes and thicknesses. It is excellently surface finished with various techniques.
Why opt for KOVAR ROUND BAR?
KOVAR ROUND BAR is well thermal conductive with lower expansion. It is prevented from heat corrosion. The hardness of the bar provides stress cracking strength at higher temperatures. It is easily welded with various systems with excellent weldability and convention techniques. It provides excellent yield properties and easily cold working ability. It demonstrates inert oxidization properties. It is easy to associate with glass and ceramic materials across a wide temperature range and forms a glass seal when combined to glass.
