一种无铅易切削高硫含锰铜合金及其制造方法技术

一种无铅易切削高硫含锰铜合金及其制造方法。合金组分以质量百分比计为：铜52.0％-95.0％，磷0.01％-0.20％，锡0.01％-20％，锰0.55％-7.0％，硫0.191％-1.0％，除锌外与硫亲和力小于锰与硫亲和力的金属一种或多种，其含量之和≤2.0％，余量为锌及和不可避免的杂质，其中除锌外与硫亲和力小于锰与硫亲和力的金属为镍、铁、钨、钴、钼、锑、铋和铌。该铜合金通过粉末冶金法制造，将合金粉末、硫化物粉和镍粉混合均匀后，进行压制成型、烧结、复压、复烧，得到所述铜合金并进行热加工处理。

A free cutting of high sulfur containing Mn Cu alloy and its manufacturing method

A free cutting of high sulfur containing Mn Cu alloy and its manufacturing method. The components of the alloy with mass percent: copper 52.0%-95.0%, 0.01%-0.20% P, 0.01%-20% 0.55%-7.0% tin, manganese, sulfur 0.191%-1.0%, except zinc and manganese and sulfur sulfur affinity is less than one or more metal affinity, and its content is less than 2%, the balance of zinc and impurities and inevitable, which except zinc and sulfur the affinity of manganese and sulfur is less than the affinity of metal nickel, iron, tungsten, cobalt, molybdenum, antimony, bismuth and niobium. The copper alloy is manufactured by powder metallurgy method, and the alloy powder, the sulfide powder and the nickel powder are uniformly mixed, and the pressing, sintering, repressing and re burning of the copper alloy are carried out, and the copper alloy is obtained.
