Metallized Carbon Corporation offers a variety of materials for mechanical seals in aircraft shaft applications, including main shaft seals for both aircraft turbine engines and aircraft auxiliary power units (APUs). The unique self-lubricating materials are impregnated with proprietary inorganic chemicals that improve their lubricating qualities and oxidation resistance. 

These modern carbon-based materials offer high thermal conductivity, which means they excel at handling and dissipating the high temperatures found in aerospace engines. The materials also feature a low coefficient of friction, a low wear rate at high sliding speed, and resistance to oxidation in high temperature air. The materials are also strong and dimensionally stable.

“Metcar’s modern carbon-graphite materials are an excellent option to help aerospace designers meet fuel efficiency requirements,” said President and CEO, Matthew Brennan, “ Since more fuel efficient engines run hotter, they need higher temperature, more thermally conductive materials in the engine.”
