Cobalt precipitant Magnesium Oxide

Magnesium oxide can be optionally added to the formulation to adjust the coefficient of friction to the desired level, and its thermal properties provide good stability and allow heat transfer from the frictional contact surfaces. Not only that, the high refractory properties of magnesia give strong resistance to high friction temperatures while maintaining grip. In addition, the moderate hardness of magnesium oxide prevents wear of the material against the metal.
