3.模具使用壽命長：預(yù)算模具的成本和生產(chǎn)的連續(xù)性，對于生產(chǎn)廠家來說模具預(yù)期的使用壽命是非常重要的，在鈹銅的強度和硬度符合要求的情況下，鈹銅對模具溫度應(yīng)力的不敏感性可以大大的提高模具的使用壽命，在確定使用鈹銅模具材料前也要考慮到鈹銅的屈服強度，彈性模量，熱導(dǎo)率和溫度的膨脹系數(shù)。鈹銅對熱應(yīng)力的抵抗性遠比模具鋼要強的多，從這一點來說鈹銅的使用壽命是令人注目的！

4.熱穿透率高：除拉導(dǎo)溫性能，模具材料的熱穿透率對塑料制品的影響也相當重要，在使用鈹青銅的模具上，可以消除過熱痕跡，如果熱穿透率低，模具壁遠端區(qū)域的接觸溫度就會越高，這樣會使模具的溫差加大，在極端的情況下會引起區(qū)域溫度的變化從塑料制品的一端的縮痕延伸到另一端的過熱的產(chǎn)品痕跡。5.優(yōu)異的表面質(zhì)量：鈹銅是非常適于表面精加工的，可以直接進行電鍍處理，而且粘著性能非常好，鈹銅的拋光處理也很容易。

黃銅以鋅作主要添加元素的銅合金﹐具有美觀的黃色﹐統(tǒng)稱黃銅。銅鋅二元合金稱普通黃銅或稱簡單黃銅。三元以上的黃銅稱特殊黃銅或稱復(fù)雜黃銅。含鋅低於36%的黃銅合金由固溶體組成
