C3771热锻性能与加工性能优良，用于空调阀、气门芯、汽车泵阀等复杂高精度零件，以及高档水暖器材、表壳、表带、豪华五金饰品、门锁、把手等。

C3771化学成分：

铜(Cu)57.0-61.0,铅(Pb)1.0-2.5,锌(Zn)余量,铁(Fe)Fe+Sn≤1.0,锡(Sn)Fe+Sn≤1.0

铅黄铜的熔炼、铸造生产并不困难，可以使用感应熔炼，坩埚熔炼等方式，铸造生产可采用半连续铸锭、砂模、铁模等;铅黄铜的压力加工性能并不优良，一般三向压应力的热加工性能尚可，热挤压为主要热变形手段，而其他热加工方式如热轧则易产生裂边现象。(α+β)两相铅黄铜热加工性能优于单相铅黄铜。铅黄铜冷加工性能较差，变形硬化大，现代铅黄铜压力加工方法中，水平连铸坯料冷加工方法发展迅速.

C3771力学性能：

抗拉强度/MPa：≥315

伸长率/%：≥15
