什么是黃銅，什么是青銅，如何辨別？

?

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(xù)鑄錠、砂模、鐵模等；鉛黃銅的壓力加工性能并不優(yōu)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(xiàn)象。（α+β）兩相鉛黃銅熱加工性能優(yōu)于單相鉛黃銅。鉛黃銅冷加工性能較差，變形硬化大，現(xiàn)代鉛黃銅壓力加工方法中，水平連鑄坯料冷加工方法發(fā)展迅速。

黃銅力學性能

（α+β）黃銅，當含鋅量增加到約為45%之前，室溫強度不斷提高。若再進一步增加含鋅量，則由于合金組織中出現(xiàn)了脆性更大的r相（以Cu5Zn8化合物為基的固溶體），強度急劇降低。（α+β）黃銅的室溫塑性則始終隨含鋅量的增加而降低。所以含鋅量超過45%的銅鋅合金無實用價值。?
黃銅是由銅和鋅所組成的合金。如果只是由銅、鋅組成的黃銅就叫作普通黃銅。黃銅常被用于制造閥門、水管、空調內外機連接管和散熱器等。更好的了解黃銅特性，對于黃銅的使用和黃銅產業(yè)的發(fā)展具有重要的意義。
