Metal-Graphite Alloys

Metal-graphite alloys have many superior properties which are not possessed by other metallic alloys, i.e. lubrication, refractoriness and porosity of graphite; strength, handness and good conductivities of heat and electricity. The typical examples of these composite are as follows: Self-lubricating Bearing Metals (graphite 1-3%) Copper-base alloys and Iron-base alloys. Pantograph Slide (graphite 2-5%) Sintered Steel (graphite 0.5-4%) Friction Products (graphite 5-10%) Electrical Contacts (graphite 5-50%) Lower graphite product (graphite below 10%) and Higher graphite products (graphite 20-50%) Metallic-Carbon Brushes (graphite 10-50%) The above alloys are manufactured by sintering process. Brief descriptions of the alloys are given.
