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.
