Product Details
Product Description and Application
K94600 is also known as Alloy 46,FeNi46,ASTM F30,Nilo 46,Glass
sealing 46,4J46
K94600 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℃
