Graphite Carbon Electrical Contacts | St Marys Carbon


Certain electrical transmission applications, e.g., rail systems, power generation, require increased electrical characteristics than our standard carbon graphite grades. We have developed specific carbon graphite grades that are capable of transmitting varying degrees of electrical current. Our proprietary mixes of carbon and metal graphite have unique performance characteristics particularly suited for dynamic electrical transmission applications. We also offer lead-free and ROHS-compliant grades to meet both your electrical and environmental requirements.

Below are the key products that are used within electrical transmission applications. However, this is not an exhaustive list and we are a custom manufacturer, so if you have any questions or needs outside of these products, please contact us directly.
