Characteristic |
Description |
Complete Metallurgical Bond | Provides complete hermetic sealing between the metals, excellent mechanical strength, ductility and greater reliability. |
Copper Core | Permits simple electrical connections and greater conductivity which allows a smaller conductor than solid for the same power requirements. |
Core Ratio | Unique processing allows any ratio of 446SS (Stainless), Alloy 52, Alloy 42-6,or Kovar® to copper can be made (i.e. diameter of glass sealing alloy to diameter of copper core).* |
Custom Processing & Other Alloys | Temper, surface finish, and packaging may all be customized to your specific requirements. Other glass sealing alloys are available on request. |
