Metal-Graphite Alloys

Abstract

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.
