MATERIAL SELECTION FOR MECHANICAL SEALS
www.911metallurgist.comMechanical carbons aremanufactured by blending together types of amorphous carbon (i.e., lampblack, charcoal, or coke) and carbon graphite with a carbonaceous binder (i.e., pitch or resins). The source of the raw materials not only helps determine the physical properties of the carbon but also the type and amount of impurities.
