KX Nilo 46 Corrosion Resistant Alloy Light Rod On Expansion Alloy
Product Description and Application
Nilo 46 is also known as Alloy 46,K94600,FeNi46,ASTM F30,Glass sealing 46,4J46
Nilo 46 is nickel-iron controlled expansion alloy containing 46% nickel. It is suitable for electric vacuum devices such as transmitting tube, oscillation tube, ignition tube, transistor, tube seal plug and relay shell.
It can be firmly sealed with hard glass with a certain coefficient of linear expansion in the temperature range of 20℃-450℃
