Kovar/UNS K94610
Kovar (UNS K94610), a nickel-iron-cobalt alloy containing approximately 29% nickel and 17% cobalt. Its thermal expansion characteristics match those of borosilicate glasses and alumina type ceramics. It is manufactured to a close chemistry range, yielding repeatable properties which make it eminently suitable for glass-to-metal seals in mass production applications, or where reliability is of paramount importance. The magnetic properties of Kovar are governed basically by its composition and by the heat treatment applied.

Nimonic 80A/UNS N07080
NIMONIC alloy 80A (UNS N07080) is a wrought, age-hardenable nickel-chromium alloy, strengthened by additions of titanium, aluminum and carbon, developed for service at temperatures up to 815°C (1500°F). It is produced by high-frequency melting and casting in air for forms to be extruded. Electroslag refined material is used for forms to be forged. Vacuum refined versions are also available. NIMONIC alloy 80A is currently used for gas turbine components (blades, rings and discs), bolts, nuclear boiler tube supports, die casting inserts and cores, and for automobile exhaust valves.

Invar alloy 36 /UNS K93600 & K93601
Invar alloy 36 (UNS K93600 & K93601), a binary nickel-iron alloy containing 36% nickel. Its very low room-temperature thermal expansion coefficient makes it useful for tooling for aerospace composites, standards of length, measuring tapes and gauges, precision components, and pendulum and thermostat rods. It is also used as the low expansion component in bi-metal strip, in cryogenic engineering, and for laser components.
