Las propiedades físicas del material de contacto son la investigación de materiales de contacto y elige uno de los índice de rendimiento importante . sus propiedades físicas, incluida la densidad, el punto de fusión, la resistividad, el coeficiente de resistencia de temperatura, la conductividad térmica, el módulo elástico y la dureza, etc. namely, physical properties and its electrical contact materials to use and has no direct corresponding relationship between performance and makes physical properties of contact materials is reference indicators, contact materials research often no standard between producers and users Prospective evaluation. Relevant national standards in our country, on the other hand, the physical properties of contact materials only for density, resistivity and hardness proposed specific indicators, its rationality, integrity, questionable.
