钨铜合金CUWRWMA10精轧钨铜板 钨铜价格
Composed of tungsten and copper alloys. Commonly used alloys of copper content of 10% ~ 50%. Preparing alloy by powder metallurgy method, has the very good conductive thermal conductivity, good high temperature strength and plasticity. At high temperatures, such as more than 3000 ℃, be evaporated liquefied alloy of copper, a large number of absorbing heat, reduce the material surface temperature. So this kind of material is also known as metal sweating.
钨铜合金有较广泛的用途,主要是用来制造抗电弧烧蚀的高压电器开关的触头和火箭喷管喉衬、尾舵等高温构件,也用作电加工的电极、高温模具以及其他要求导电导热性能和高温使用的场合。
钨铜采用等静压成型—高温烧结钨骨架—溶渗铜的工艺,是钨和铜的一种合金。
电阻焊电极
综合了钨和铜的X点,耐高温、耐电弧烧蚀、强度高、比重大、导电、导热性好,易于切削加工,并具有发汗冷却等特性,由于具有钨的高硬度、高熔点、抗粘附的特点,经常用来做有一定耐磨性、抗高温的凸焊、对焊电极。
电火花电极
针对钨钢、耐高温X硬合金制作的模具需电蚀时,普通电极损耗大,速度慢。而钨铜高的电腐蚀速度,低的损耗率,X的电极形状,X良的加工性能,能保证被加工件的X度大大提高。
