KX Glass Sealing 52 Corrosion Resistant Alloy Light Rod On Expansion Alloy
Product Description and Application
Glass Sealing 52 is also known as Alloy 52,Alloy 52,Pernifer
50,52H(E),N14052.
Glass Sealing 52 Fe-Ni constant expansion alloy is a series of
constant expansion alloys that can match soft glasses and ceramics
with different expansion coefficients in a given temperature range
by adjusting nickel content. The expansion coefficient and Curie
point increase with the increase of nickel content. This alloys is
widely used as sealing structural materials in electric vacuum
industry.
