铝及铝合金的化学成分是保证合金组织、产品性能的基本条件。化学成分的分析一直被铝业界所重视,早在四十年代,英国就制订了铝及铝合金化学分析标准方法,近几十年来,由于铝合金的用途越来越广,对铝合金中的分析元素也越来越多,分析方法也多种多样,特别是近几年来,电子计算机的出 The chemical composition of aluminum and aluminum alloy is to ensure that the basic conditions of alloy organization, product performance. Analysis of chemical composition has been the aluminum industry attention, as early as the forties, the United Kingdom developed a standard method of chemical analysis of aluminum and aluminum alloy method, in recent decades, the use of aluminum is more and more widely used in aluminum alloys Analysis of the elements are also more and more analysis methods are varied, especially in recent years, the computer out
