Kovar Sheet from Stock
Product Announcement from Ed Fagan, Inc.
Kovar Alloy, 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 Sheet in thicknesses of .001", .004", .005", .010", .015", .020", .025", .030", .035", .040", .050", .060", .0625", .070", .072", .078", .080", .083", .090", .093", .094", .10", .105", .107", .115", .120", .125", and.125" as standard sizes, and EFI can cut these to your specifications. All standard in-stock Kovar Sheet items can be shipped within 24 hours - and are often shipped the same day - and all materials can be certified with shipment. If you need other forms of Kovar Alloy, EFI also stocks Kovar in Rod, Bar, Plate, Photo-Etch, as well as Strip/Coil in both Annealed and Tempered conditions.
