As a leader in the production of high-technology clad-metal products, Anomet applies this technology to the production of copper cored glass sealing alloys.  These glass-to-metal sealing (GTMS) alloys result in a high quality product with uniform hermetic sealing characteristics capable of carrying up to six times more current than the same size solid wire.

Characteristics of Anomet's Copper Cored Glass-to-Metal Sealing Alloys

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.
