Kovar Alloy 4J29 Plate , Invar Alloy 4J32,4J33,4J34,4J36 Sheet

Kovar Alloy 4J29 Plate is an iron cobalt nickel alloy with a thermal expansion coefficient similar to that of hard glass. As Kewa alloy is tough and versatile, extensive quality control is applied in the manufacturing process of UNS K94610 alloy to ensure uniform physical and mechanical properties, making drawing, stamping and processing easier. In addition, Kova? It is the most dynamic mechanical performance.
