4J33Fixed expansion ceramic sealing alloy, executive standard: YB/T5231-2005
Characteristic: Maintain a certain coefficient of expansion within a certain temperature range, which α (20100)=(411) × 10-6-1. The expansion coefficient of this alloy is similar to that of glass, ceramics, and mica, and can be matched (or unmatched) for sealing, so it is also called a sealing alloy. It is widely used as a sealing, lead, and structural material in electronic tubes, transistors, integrated circuits, and other vacuum devices.
