Product Description

4J46

Uses: Used to make iron-nickel-cobalt alloy strips, rods, plates, and pipes that are matched and sealed with hard glass.

It is suitable for electric vacuum devices such as launch tubes, oscillating tubes, ignition tubes, transistors, tube seal plugs, and relay casings.

It has a certain linear expansion coefficient in the temperature range of 20°C-450°C, and can be matched with hard glass and sealed firmly.
