Porous low-density metal friction plate material

Abstract

The invention discloses a porous low-density metal friction plate material. The porous low-density metal friction plate material comprises the following components of, by weight, 1-3 parts of silicon, 3-6 parts of copper, 50-60 parts of iron, 0.2-0.5 part of manganese, 0.1-0.55 part of carbon, 8-10 parts of aluminum, 12-15 parts of calcium and 0.25-0.35 part of chromium. The porous low-density metal friction plate material has the beneficial effects that the metal friction material is good in mechanical performance, high in plasticity and density and stable in friction coefficient, and the service life is greatly prolonged.

Description

technical field [0001] The invention relates to a metal friction plate material, in particular to a porous low-density metal friction plate material. Background technique [0002] With the development of the automobile industry and the improvement of environmental protection awareness in modern society, the working conditions of automobile brake friction materials are becoming more and more harsh, and their performance requirements are also getting higher and higher. For example, brake friction materials are required to have sufficient and stable friction coefficients , Good thermal conductivity, large heat capacity, certain high-temperature mechanical strength, good wear resistance and anti-adhesion, not easy to scratch the counterpart, no noise, low cost, no pollution to the environment, etc. [0003] Composites are a mixture. It has played a great role in many fields and replaced many traditional materials. Composite materials are divided into metal and metal composite ...
