Metco 308 is a graphite cermet powder used in a combustion gas spray gun such as the Metco 6p gun or equivalent. It is used itraptionn gas turbine and jet engines' compressors for clearance control in service temperatures up to 900 degrees Fahrenheit (480 Celsius). Composed of 85% nickel and 15% graphite, Metco 308 produces what is essentially a oxide free machine element seal and clearance coatings for gas turbine engines.

Both Metco 307 and 308 have the same chemical structure, but the particle sizes are different. Metco 307 is more abradable and less erosion-resistant than 308.
