Product Description and Application

 

4J50 is also known as Alloy 52,Glass sealing 52,Pernifer 50,52H(E),N14052.
4J50 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.
