C3771熱鍛性能與加工性能優良，用于空調閥、氣門芯、汽車泵閥等復雜高精度零件，以及高檔水暖器材、表殼、表帶、豪華五金飾品、門鎖、把手等。

C3771化學成分：

銅(Cu)57.0-61.0,鉛(Pb)1.0-2.5,鋅(Zn)余量,鐵(Fe)Fe+Sn≤1.0,錫(Sn)Fe+Sn≤1.0

鉛黃銅的熔煉、鑄造生產并不困難，可以使用感應熔煉，坩堝熔煉等方式，鑄造生產可采用半連續鑄錠、砂模、鐵模等;鉛黃銅的壓力加工性能并不優良，一般三向壓應力的熱加工性能尚可，熱擠壓為主要熱變形手段，而其他熱加工方式如熱軋則易產生裂邊現象。(α+β)兩相鉛黃銅熱加工性能優于單相鉛黃銅。鉛黃銅冷加工性能較差，變形硬化大，現代鉛黃銅壓力加工方法中，水平連鑄坯料冷加工方法發展迅速.

C3771力學性能：

抗拉強度/MPa：≥315

伸長率/%：≥15
