摘要
The present invention provides a lead-free easy-to-cut corrosion-resistant brass alloy with good thermoforming performance. The brass alloy contains: 74.5-76.5wt% of Cu, 3.0-3.5wt% of Si, 0.11-0.2wt% of Fe, 0.04-0.10%wt% of P, Zn and inevitable impurities. The alloy provided by the present invention has good cold-working and hot-working forming performance, and good dezincification corrosion-resistant and stress corrosion-resistant performance, applies to parts that require cutting and grinding forming in water-heating sanitaryware, electronic appliances, automobiles and the like, and especially applies to production and assembling of complex forging products for which stress is inconvenient to eliminate, such as water taps, values and the like.
