Alloy 42 iron-nickel constant expansion alloy is a series of constant expansion alloys that can match soft glass and ceramics with different expansion coefficients within a given temperature range by adjusting the nickel content. Its expansion coefficient and Curie point increase with the increase of nickel content. This alloy is a widely used sealing structural material in the electric vacuum industry.

KOVAR, also known as ASTM F 15 alloy, is a controllable expansion alloy commonly used in metal seals, covers, lead frames, and electronic packaging bases for high integrity glass and ceramics. Kovar is made of nickel, cobalt, and iron. This alloy is designed to meet the technological needs of the computer, microwave, hydride, semiconductor, and space age, making it an important resource for the defense, aerospace, and telecommunications industries.
