什么是黄铜，什么是青铜，如何辨别？

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。

黄铜力学性能

（α+β）黄铜，当含锌量增加到约为45%之前，室温强度不断提高。若再进一步增加含锌量，则由于合金组织中出现了脆性更大的r相（以Cu5Zn8化合物为基的固溶体），强度急剧降低。（α+β）黄铜的室温塑性则始终随含锌量的增加而降低。所以含锌量超过45%的铜锌合金无实用价值。 
    黄铜是由铜和锌所组成的合金。如果只是由铜、锌组成的黄铜就叫作普通黄铜。黄铜常被用于制造阀门、水管、空调内外机连接管和散热器等。更好的了解黄铜特性，对于黄铜的使用和黄铜产业的发展具有重要的意义。
