Kovar parts and prototyping: CNC Machining

ASTM F15 alloy (Kovar®) is a controlled expansion alloy most commonly used for high integrity glass and ceramic to metal seals, lids, lead frames and electronic package base. Kovar itself is 29 percent nickel, 17 percent cobalt, and a balance of iron and other trace elements.

Kovar Tech Data - High Temp Metals

Kovar alloy has been used for making hermetic seals with the harder Pyrex glasses and ceramic materials. This alloy has found wide application in power tubes, microwave tubes, transistors and diodes. In intergrated circuits, it has been used for the flat pack and the dual-in-line package.

Kovar is very similar to another nickel alloy referred to as Invar. Invar is a nickel steel alloy with specific thermal expansion properties; however, Invar is unique for its low thermal expansion qualities, while Kovar is for its low thermal expansion in terms of its compatibility to heat-resistant glass.

PHYNICX large stock in alloys

Created in 1930. This Ni-Co alloy has two typical applications. Between 20-500 °C, KOVAR (alloy K) has the lowest CTE of all alloys or metals. But its CTE is also equal to glass and ceramics. Making it an ideal metal to seal glass metal or ceramic-metal. Many glass sealing systems are built up with KOVAR.

Kovar alloy is a vacuum smelting of iron, nickel, and cobalt is of low expansion alloy, chemical composition content is controlled within a very narrow range to ensure accurate equilibrium thermal expansion properties.

Kovar Alloy Machining Tips from National Electronic Alloys

When machining Kovar (ASTM F15 alloy) it tends to be quite gummy. Tools have a tendency to plow right through the metal rather than chip away at it. It is important to keep complete control over your heating when machining Kovar, as too much of a heat buildup will cause the alloy to warp.
