KX 42HA(Russian) Corrosion Resistant Alloy Light Rod On Expansion Alloy
Product Description and Application
42HA(Russian) Fe-Ni constant expansion alloy is a series of
constant expansion alloys which can be matched with soft glass and
ceramic with different expansion coefficient in a given temperature
range by adjusting the nickel content. The expansion coefficient
and Curie point of 42HA(Russian) Fe-Ni constant expansion alloy would increase with the nickel
content increase . The alloy is a widely used sealing structure
material in the electric vacuum industry, which is used to match
the sealing with soft glass and ceramic on the production of
electrical components, matching and sealing with corresponding soft
glass in electric vacuum industry.
