ASTM F30 Expansion Alloy Corrosion Resistant Alloy Rod
KX ASTM F30 Corrosion Resistant Alloy Light Rod On Expansion Alloy
Product Description and Application
ASTM F30 is also known as Alloy 46,K94600,FeNi46,Nilo 46,Glass sealing 46,4J46
ASTM F30 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℃
