一、引子高比重合金是以钨为基体,加入一定量铜、铁、钴、镍、锰、钼、铬等元素所组成的一种新型金属材料,由于其比重大,强度高,良好的吸收射线能力,及较低的热膨胀系数,而广泛应用于空间技术、军事、电气、仪器等国民经济各部门。我厂主要以W-Co、Fe、Cu、Ni、Mn型为主,为提高分析精度,我们对原子吸 First, the high proportion of the lead alloy is based on tungsten as a matrix, adding a certain amount of copper, iron, cobalt, nickel, manganese, molybdenum, chromium and other elements of a new type of metal material, due to its large proportion, high strength, good absorption Ray capabilities and low coefficient of thermal expansion, which are widely used in various sectors of the national economy such as space technology, military, electrical and instrumentation. I plant mainly W-Co, Fe, Cu, Ni, Mn-based, in order to improve the accuracy of analysis, we Atomic Absorption
