什么是黃銅,什么是青銅,如何辨別?
黃銅是以銅為基體的銅與鋅的合金,牌號以“H”打頭,后跟兩位數(shù)是銅的平均含量;除黃銅和白銅(銅與鎳的合金)外的所有以銅為基體的銅合金都稱為青銅。常用的主要有錫青銅、鉛青銅、鋁青銅、鈹青銅等。牌號以“Q”打頭,后跟主加元素的符號及平均含量,再跟次加元素符號及平均含量。肉眼分辨只能從顏色觀察上進行,黃銅較亮,青銅較暗。
黃銅主要品種有:普通黃銅(如H65)、鎳黃銅(如HNi65-5)、鐵黃銅、鉛黃銅、鋁黃銅、錳黃銅、錫黃銅、加***黃銅、硅黃銅等。黃銅從牌號上可以明確的分辨出來,***位字母H 表示黃銅類,次位字母表示主要添加元素,***組數(shù)字表示銅的含量,以后的數(shù)字依次表示其它主要元素含量;黃銅的顏色一般較為鮮亮,多呈***。
青銅的主要品種有:錫青銅(如QSn4-3)、鋁青銅(如QAl9-2)、鈹青銅、硅青銅、錳青銅、鋯青銅、鉻青銅、鎘青銅、鎂青銅、鐵青銅、碲青銅等。青銅牌號***位字母Q 表示青銅類,次位字母表示主要添加元素,以后的字母表示其它主要元素。***位數(shù)字表示除銅外主要元素的含量,以后數(shù)字表示其它主要元素的含量。外觀上青銅顏色晦暗。
鉛黃銅的熔煉、鑄造生產(chǎn)并不困難,可以使用感應(yīng)熔煉,坩堝熔煉等方式,鑄造生產(chǎn)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(yīng)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(chǎn)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。
