KX K94100 Corrosion Resistant Alloy Light Rod On Expansion Alloy
Product Description and Application
K94100 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 K94100 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.
