Materials
We take great pride in the fact that we are one of the few carbon companies across the world to make our own customized grades. Each grade is made in-house by our specialized craftsmen based on over 75 years of experience in the carbon industry.We manufacture proprietary composite materials and discrete components for both static and dynamic applications. These components can be manufactured in segments or as monoliths, and our manufacturing methods range from fully machined tight tolerance to net shape manufacturing to reduce cost for high volume applications.
As a custom manufacturer, we are able to modify our grades or production processes or even develop new grades and processes to meet your specific needs.These materials are developed to provide unique characteristics to meet a variety of application requirements:
Carbon Graphite materials are a composite of different carbon materials and inorganic additives which have exemplary performance in demanding applications in either wet or dry applications. Carbon Graphite Materials are preferred for many different applications because of their unique combination of characteristics.
Learn MoreElectrographite materials have been processed to extremely high temperature to transform carbon raw materials to graphite. This process provide multiple benefits including dramatically increases Thermal Conductivity, Electrical Conductivity, Oxidation Resistance and Chemical Resistance.
Learn MoreResin-bonded Carbon Graphite materials consist primarily of resin with varying degrees of carbon graphite injections to provide for specialized properties. These materials do not go through the coking and impregnation process.
Learn MoreCarbon Graphite or Electrographite can be modified through Silver impregnation. Molten Silver is impregnated into these base materials to impart additional benefits to the materials making them ideal for certain end-use applications. Silver further enhances the Carbon Graphite or Electrographite.
Learn MoreThis family of materials combines the high Electrical Conductivity of copper with other metal and graphite raw materials to produce proprietary materials with unique performance characteristics particularly suited for dynamic electrical transmission applications.
Learn MoreImpregnation with Antimony is uniquely efficient at reducing porosity in Carbon/Graphite and Graphite materials. This is due in part to the low Surface Temperature of the molten metal.
Learn MoreBabbitt alloys generally melt in the range of 433 oF (223 oC) to 479 oF (248 oC) which significantly constrains its application temperature limits as the Seal Face or Bearing Surface can be significantly above the process temperature
Learn MoreOne of the main benefits to being a St. Marys Carbon customer is that we are one of the few carbon companies globally to develop our own proprietary materials. This means that our products will be fully customized to your specific application from start to finish.
