Miljøvenlig mangan-messing-legering og fremgangsmåde til fremstilling af denne

摘要

The present invention provides an environment-friendly manganese brass alloy, which comprises 55ˆ¼65wt% of Cu, 1.0ˆ¼6.5wt% of Mn, 0.2ˆ¼3.0wt% of Al, 0ˆ¼3.0 wt% of Fe, 0.3ˆ¼2.0wt% of Sn, 0.01ˆ¼0.3wt% of Mg, 0ˆ¼0.3wt% of Bi and /or 0ˆ¼0.2wt% of Pb, the balance being Zn and unavoidable impurities. The alloys not only have superior mechanical properties, castability, cutability and corrosion resistance, especially stress corrosion resistance properties, but also have the advantages of low manufacturing costs and simple manufacturing process etc, which is suitable for making components through forging, casting, cutting and other manufacturing methods, especially suitable for making water tap bodies and valves through forging, casting and cutting processes.
