The invention discloses environmental self-lubricating wear-resistant
copper alloy, comprising the following components by
mass percent: 5-13% of Sn, 2-9% of Ni and / or Co, 2-11% of Bi, 0.05-0.3% of Zr, 0.05-0.5% of RE, the balance of Cu and inevitable impurities, wherein the content of the
impurity is smaller than or equal to 0.3%, the RE is Ce-La
misch metal. Meanwhile, the preparation method of the environmental self-lubricating wear-resistant
copper alloy is disclosed. The environmental self-lubricating wear-resistant
copper alloy has the advantages that the conventional wear-resistant
copper alloy containing lead is replaced, and the environmental self-lubricating wear-resistant
copper alloy is the wear-resistant
copper alloy material with environment-friendly and self-lubricating effects. The alloy solidification molding process is interfered by adopting a strong pulsed electromagnetic
physical field in the manufacturing process, the as-cast segregation and loosening of the obtained environmental self-lubricating wear-resistant copper alloy are significantly reduced, the alloy is fine and even in as-cast structure, and high in density, the
hardness of the molded
casting is greater than 70HB, the tensile strength is greater than 230MPa, and the alloy density is greater than 8.7g / cm<3>. The environmental self-lubricating wear-resistant copper alloy has good overall performance, the preparation method is good in stability, and low in cost, the preparation process is green and free of
pollution, and industrialization is easily achieved.
