钨铜 W75硬质合金【W75钨铜棒
W75 tungsten copper features: tungsten copper is the use of high purity tungsten metal powder excellent features and advantages of high purity copper powder plasticity, high conductivity, the static pressure molding, high temperature sintering process of copper, soluble permeability composite materials refined but become. Arc breaking performance is good, good conductive heat conduction, thermal expansion of small, high temperature does not soften, high strength, high density, high hardness. Purpose: 1. Resistance welding electrodes, taking advantages of tungsten and copper, high temperature resistance, arc ablation resistance, high strength, better than major, conductive, thermal conductivity, easy to machining, and has the characteristics such as sweating ling but, because of its high hardness, high melting point, resistance of tungsten adhesion characteristics, often used to do some abrasion resistance, resistance to high temperature of projection welding, butt welding electrode.
W75钨铜特性:钨铜是利用高纯钨粉优异的金属特性和高纯紫铜粉的可塑性、高导电性等优点,经静压成型、高温烧结、溶渗铜的工艺精制而成的复合材料。断弧性能好,导电导热好,热膨胀小,高温不软化,高强度,高密度,高硬度。
用途: 1.电阻焊电极：综合了钨和铜的优点,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,并具有发汗泠却等特性,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。
