Nilo 46 Corrosion Resistance Alloy Light Rod Weldability
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℃
