A low-cost lead-free dezincification corrosion-resistant brass alloy for casting. The brass alloy contains: 60-65 wt. % of Cu, 0.05-0.25 wt. % of Pb, 0.05-0.8 wt. % of Al, 0-0.1 wt. % of Sn, and 0.05-0.16 wt. % of As, with the balance being Zn and inevitable impurities. Moreover, the equivalent weight of zinc X meets the requirements of the following formula: 35%&#x3c;X&#x3c;39.5%, and X=(B+&#x3a3;CiKi/(A+B+&#x3a3;CiKi); in the formula, X is the equivalent weight of zinc in the complex brass, A is the copper content (%), B is the actual zinc content (%), Ci is the content (%) of the other alloy elements, and CiKi is the corresponding equivalent weight of zinc of various elements.
