Kovar Alloy Machining Tips from National Electronic Alloys

Nickel alloys usually harden quite rapidly, and the high pressures that machining creates causes hardening and slows down progress, also causing warping in some of the material. Make sure you have a rigid setup, work at a slow speed, and try using sulfurized mineral oil. When machining Kovar (ASTM F15 alloy) it tends to be quite gummy. Tools have a tendency to plow right through the metal rather …
