Kovar Iron Nickel Alloy Plate

Product Details

Kovar, also know as ASTM F-15, NILO K, Pernifer 2918, Rodar, and Dilvar P1, is a Nickel Iron controlled expansion alloy with 29% Nickel, 17% Cobalt and the remaining balance Iron. Kovar expansion characteristics match both borosilicate (or Pyrex) glasses and alumina ceramics making it one of the most popular of the controlled expansion alloys for hermetic sealing applications.

Ed Fagan Inc. stocks Kovar Plate in thicknesses .175", .1875", .200", .210", .215", .220", .230", .250", .281", .3125", .375", .4375", .500", .625", .687", .750", .875", 1.000", 1.500", 1.750", and 2.000" as standard sizes, and EFI can cut these to your specifications.
