Abstract
The present invention provides an environment-friendly manganese brass alloy, which comprises 55˜65 wt % of Cu, 1.0˜6.5 wt % of Mn, 0.2˜3.0 wt % of Al, 0˜3.0 wt % of Fe, 0.3˜2.0 wt % of Sn, 0.01˜0.3 wt % of Mg, 0˜0.3 wt % of Bi and/or 0˜0.2 wt % 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.
