Disclosed is a brass which exhibits high corrosion resistance even without undergoing a heat treatment step for inhibiting dezincification corrosion. This brass comprises 55 to 75 mass% of Cu and 0.01 to 1.5 mass% of Si, contains Sn and Al in such amounts as to satisfy prescribed relationships with the apparent zinc content, and further contains, as optional components, less than 0.25 mass% of Mn, less than 0.05 mass% of Ti, less than 0.3 mass% of Mg, less than 0.15 mass% of P, and less than 0.004 mass% of a rare earth metal, with the balance consisting of Zn and unavoidable impurities. The brass has an apparent zinc content of 37 to 45. |
