Die physikalischen Eigenschaften des Kontaktmaterials sind Kontaktmaterialforschung und wählen einen der wichtigsten Leistungsindex . seine physikalischen Eigenschaften einschließlich Dichte, Schmelzpunkt, Widerstand, Temperaturkoeffizient der Resistenz, thermische Leitfähigkeit, elastischer Modul und Härte usw. führen. using state, 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, fragwürdig .
