Custom Solutions

Each of our industrial brushes can be custom-manufactured to your specific requirements. We develop our own proprietary grades and manufacture each product in-house, so we will work closely with you to find the right brush grade or develop new grades to optimize your product’s performance, reduce wear and decrease costly maintenance.

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 our brushes to be used in a variety of harsh environments without damage to the brush or your equipment.

Low Friction / Wear

The self-lubricating properties of our brushes will greatly reduce the amount of friction and brush wear during operation, significantly reducing maintenance time, brush 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.


Our brushes are 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 our brushes can withstand high temperatures, they are 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 our brushes to be used in harsh environments while maintaining brush performance.</
