It is a Fe-Ni alloy containing 42% nickel and similar characteristics of themal expansion to hard glass or ceramics. It exhibits the characteristics of the low thermal expansion over a range of temprature, which is particularly sutable for electrode of electrical parts to be sealed with glass. It is prescribed at American Industrial Standard what is called ASTMF30 and generally sold as ASTMF-30 similar products by Japanese manufacturers. We have started manufacturing Alloy 42 as the alernative of Kovar because Kover is added in Specified Chemical Substances, or Hazardous Chemical Subtances.
