As a professional supplier in the production of high-technology clad-metal products, Copper-cored Materials 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.

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.

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.
