一、概述 钨基合金(又称钨基高比重合金)具有许多特有的优良性能,诸如比重高、强度大,吸收射线性能好,热膨胀系数小,导热性好,耐腐蚀和易切削加工等等。因此在军事工业和国民经济的许多部门获得广泛的应用,例如航空工业中的各种配重,陀螺仪转子、手表重锤、吸收射线的屏蔽材料,穿甲弹弹芯和压铸模等等.尤其是钨基合金用于制做压铸模,是一种好材料。 从80年代初起着手进行了用于铜合金压铸模具的钨基合金材料研究工作,研制成了 First, an overview of tungsten-based alloy (also known as tungsten-based high specific gravity alloy) has many unique excellent properties, such as high specific gravity, high intensity, good absorption of radiation, thermal expansion coefficient, thermal conductivity, corrosion resistance and cutting and so on . It is widely used in many sectors of the military industry and the national economy, for example, various counterweights in the aerospace industry, gyroscope rotors, watch hammers, radiation shielding materials, armor piercing cores, die-casting molds, etc. In particular Tungsten-based alloy used to make die-casting mold, is a good material. From the early 1980s began to work on the copper alloy die-casting mold tungsten alloy materials research work, developed
