Product Description and Application
Nilo K is also know as Ni29Co18, 4J29
Nilo K is a typical Fe-Ni-Co hard-glass sealing alloy, which has been used in aviation factories for a long time with stable performance. The alloy has a dense oxide film, which can be well infiltrated by glass. It is the main sealing structural material of electric vacuum devices and mainly used for the glass sealing of electric vacuum components such as transmitter tube, oscillation tube, ignition tube, magnetron, transistor, sealing plug, relay, lead line of integrated circuit, chassis, shell, bracket and etc.
