Commonly used for compression (reinforced) seals
- The 46 glass ceramic is a structurally homogeneous material which combines the wettability of electronic glasses with the strength of ceramics.
- The 46 replaces alumina and other glass/ceramics requiring batch furnace processing and reduces furnace time by 80%.
- With 46, metallizing and brazing steps are eliminated.
- The 46 produces high strength seals that can withstand temperatures up to 700°C.
- Sealed glass-ceramic headers can be post brazed up to temperatures of 1400°F without affecting hermeticity.
- The 46 has variable coefficient of thermal expansion from 110 to 220 (x 10-7 in/in/°C).
The 46 Ceramic Glass Composite:
- Eliminates manufacturing steps
- Reduces sealing time
- Can match a wide range of metals
- Can be easily machined
- Has improved high temperature electrical properties
- Has improved chemical durability
