Relative Grade: 4J50 FeNi50 Nilo51 NS-1 N50 Vacovit 500
Specification: Sheet/Plate, Bar/Rod/Wire/Coil,Capillary/Pipe/Tube
Precision alloy 4J50 is a Fe-Ni constant expansion alloy, which obtains matchable expansion coefficient with different soft glass and ceramic in given temperature range by adjusting the nickel content, and the expansion coefficient and Curie point are increased with the nickel content increase. 4J50 alloy is a widely used sealing material in electric vacuum industry
