Description:

Kovar alloy is a vacuum melted, iron-nickel-cobalt, low expansion alloy whose chemical composition is controlled within narrow limits to assure precise uniform thermal expansion properties. Extensive quality controls are employed in the manufacture of this alloy to ensure uniform physical and mechanical properties for ease in deep drawing, stamping and machining.

Our production process for Kovar alloy is first melted using Vacuum Induction Melting (VIM) techniques. A secondary melt operation, Electro Slag Remelt (ESR), is then employed to further remove impurities and improve overall homogeneity.
