Glass Recommendations for Molybdenum

Hermetic Seal Glass for Molybdenum

Common Applications: Glass Coating, Hermetic Seal, Filaments

Composition: Molybdenum
Coefficient of Thermal Expansion: 55 x 10-7 / °C
Seal Type Recommended Elan Glass Equivalent Glasses
  Corning GE Kimble
Matched 19


Material Summary:
Molybdenum is a high density low expansion material with 2600 °C melting points. Its properties make it ideal for use as filaments and glass coating in high temperature applications like aircraft engines. Elan 19 glass can create a matched hermetic seal with a molybdenum pin or housing. Other applications include combining Molybdenum pins with Stainless Steel housings for compression sealing.
