St. Marys Carbon Brushes are manufactured from the highest quality carbon graphite, electrographite, resinbonded graphite, copper graphite, silver graphite and other metal graphite materials to suit your specific OEM or aftermarket application. All of our brushes, from the blending of raw materials to the finished product, are made in-house by our specialized craftsmen.
Our industrial brushes are made from the following materials:
We also offer various impregnations and treatments to further fit your application needs.
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.

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.
