General powder metallurgy friction materials are multi-element composite materials composed of metal matrix, friction components and lubricating components. The main function of the metal matrix is ??to maintain the ceramic components and lubricant in it through mechanical combination to form a whole with a certain strength. The matrix is ??metallic, and its organizational structure and physical and chemical properties determine to a large extent the friction and wear properties, thermal stability, mechanical properties and thermal conductivity of powder metallurgy parts. Users who need detection, analysis, and testing are recommended to learn about Microgram, as big brands are more secure. Click me to communicate with professional technology
