The inventive copper alloy wear-resistant material comprises the following ingredients based on weight ratio: 54%-57% of Cu, 3%-5% of Al, 3.5%-5.5% of Mn, 0.5%-1.3% of Si, 0.7-1.5% of Fe, not more than 1% of impurities, and Zn as the balance. The invention is suitable for the production field of alloy wear resistant material.

Description

technical field [0001] The invention relates to the field of metal wear-resistant materials, in particular to a copper alloy wear-resistant material and a preparation method thereof. Background technique [0002] Before the 1970s, most wear-resistant materials were made of bronze. Bronze was expensive, and due to the limitation of thermoforming performance, the application field was limited. Since the 1970s, all countries in the world have invested energy in the research of multi-component brass, and successively formed a variety of complex and wear-resistant brass grades. [0003] In the current common copper alloy wear-resistant materials, there are mainly the following technical problems: [0004] 1. The high content of precious metals, high manufacturing costs, and high use costs limit the application range and fields of materials; [0005] 2. The production method has a significant impact on the wear resistance of copper alloy wear-resistant materials, which seriously...
