Precision Kovar (4J29/Vacon 12) Micro Tubing | 1mmx0.5mm & 2mmx0.5mm for Electronic Packaging
Iron-nickel-cobalt alloy 4J29 alloy is also called Kovar alloy. 4J29 has a linear expansion coefficient close to that of silicon boron hard glass at 20 ° C to 450 ° C, which can be matched with hard glass to achieve sealing firmly. It has a high Curie point and has good low temperature tissue stability.
4J29 is mainly used for the glass sealing of electric vacuum components such as launch tubes, oscillation tubes, ignition tubes, magnetrons, transistors, sealed plugs, relays, integrated circuits, chassis, housings, brackets, etc.

When the average linear expansion coefficient reaches the standard stipulated conditions, the content of nickel and cobalt is allowed to deviate from the range specified in the table. The contents of aluminum, magnesium, zirconium and titanium are each not more than 0.10%, and the total amount should not be more than 0.20%
