Abstract

The invention discloses a high-intensity wear-resisting complex copper alloy material and a preparation method thereof. The alloy material comprises the following components in percentage by weight: 63-66% of Cu, 4.5-6.0% of Al, 7.0-8.5% of Mn, 1.0-2.0% of Si, 0.5-1.5% of Fe, 0.3-0.8% of Pb, less than 0.5% of Ni, less than 0.5% of Sn and the balance of Zn. The alloy material has the advantages that good comprehensive mechanical property is achieved, a gear ring made of the alloy material is excellent in abrasion property, the preparation cost of the alloy material is relatively low, the strength of the alloy material is enhanced through metal Al, and the high-hardness wear-resisting Mn5Si3 strengthening phase is formed by metal Mn and Si, so that the wear-resisting property is improved; the cutting machining property of cast brass is effectively improved through adopting the metal Pb, so that the wear resistance is improved; as the quaternary intermediate alloy is subjected to alloying, the melting point of the alloy is lower than the melting point of a high melting point element, so that the melting efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of metal smelting, in particular to a high-strength wear-resistant complex copper alloy and a manufacturing method thereof. Background technique [0002] The synchronizer ring is an auto part used in the transmission of the car, and the material is generally copper alloy. However, the multi-component complex copper alloy materials currently used either have better wear resistance or better mechanical properties, or have better wear resistance and mechanical properties but relatively high material and manufacturing costs, lacking a combination of better performance and lower cost lower material. [0003] While the synchronizer industry is pursuing the development of copper alloy gear ring materials with better comprehensive performance, the pressure from cost is becoming more and more obvious, which runs counter to the market's price requirements. There is an urgent need to develop a relatively low-cost co...
