3.模具使用寿命长：预算模具的成本和生产的连续性，对于生产厂家来说模具预期的使用寿命是非常重要的，在铍铜的强度和硬度符合要求的情况下，铍铜对模具温度应力的不敏感性可以大大的提高模具的使用寿命，在确定使用铍铜模具材料前也要考虑到铍铜的屈服强度，弹性模量，热导率和温度的膨胀系数。铍铜对热应力的抵抗性远比模具钢要强的多，从这一点来说铍铜的使用寿命是令人注目的！

4.热穿透率高：除拉导温性能，模具材料的热穿透率对塑料制品的影响也相当重要，在使用铍青铜的模具上，可以消除过热痕迹，如果热穿透率低，模具壁远端区域的接触温度就会越高，这样会使模具的温差加大，在极端的情况下会引起区域温度的变化从塑料制品的一端的缩痕延伸到另一端的过热的产品痕迹。5.优异的表面质量：铍铜是非常适于表面精加工的，可以直接进行电镀处理，而且粘着性能非常好，铍铜的抛光处理也很容易。

黄铜以锌作主要添加元素的铜合金﹐具有美观的黄色﹐统称黄铜。铜锌二元合金称普通黄铜或称简单黄铜。三元以上的黄铜称特殊黄铜或称复杂黄铜。含锌低於36%的黄铜合金由固溶体组成
