C18665-1/2H CAC16-1/2H銅帶性能好力學(xué)性能高

概述

含鋁量一般不超過(guò)11.5%，有時(shí)還加入適量的鐵、鎳、錳等元素，以進(jìn)一步改善性能。鋁青銅可熱處理強(qiáng)化，其強(qiáng)度比錫青銅高，抗高溫氧化性也較好。

有較高的強(qiáng)度 良好的耐磨性 用于強(qiáng)度比較高的螺桿、螺帽、銅套、密封環(huán)等，和耐磨的零部件,zui突出的特點(diǎn)就是其良好的耐磨性。

為含有鐵、錳元素的鋁青銅有高的強(qiáng)度和耐磨性，經(jīng)淬火、回火后可提高硬度，有較好的高溫耐蝕性和抗氧化性在大氣、淡水和海水中抗蝕性很好，可切削性尚可，可焊接不易釬焊，熱態(tài)下壓力加工良好。我國(guó)已能量產(chǎn)。
