Key Advantages of St. Marys Carbon Electrical Contacts:

Stability at High Temperatures

Our proprietary mix of carbon graphite is able to withstand extreme temperatures, which allows ARC to be used in a variety of harsh environments without damage to the ARC contact or your equipment.

Low Friction / Wear

The self-lubricating properties of ARC will greatly reduce the amount of friction and wear during operation, significantly reducing maintenance time, replacement and equipment damage.

High Conductivity

Only the purest metals and materials are used to provide for consistently high conductivity and our ability to custom-design means that we can adjust the mix of our materials to meet your specific conductivity needs.


ARC is self-lubricating, meaning that a separate lubricant (e.g., oil) is not required, which allows them to be used in both dry-running and sanitary environments.


As ARC can withstand high temperatures, it is resistant to melting or welding to your equipment during operation, allowing your equipment to run longer and perform better.


Our proprietary mix of carbon graphite resists chemical degradation of the surface material, allowing ARC to be used in harsh environments while maintaining performance.
