Kovar Nickel Test Panels

Metaspec makes test panels, specimens, and coupons from ASTM F15 Kovar nickel, an iron-nickel-cobalt alloy. Kovar has similar coefficient of thermal expansion (CTE) to glass, which makes it useful for metal-to-glass bonds or joins. These test panels are available in a wide range of sizes, including 1" x 2", 2" x 4", 3" x 6", 3" x 10", and 4" x 6". Custom test panels are available on request.
