Impurity alloy
Witryna1 mar 2016 · The content of impurity iron in the primary magnesium is usually higher than 100 ppm, which is thought to be one of the main causes of poor corrosion resistance and low plasticity in commercial magnesium alloys. So far, several methods have been used to purify the magnesium alloy melt. WitrynaThe determination of trace impurities in high-purity metals and alloys is an impor-tant part of the quality-control process in the manufacture of these materials. Trace impurities can have major effects on the properties of the finished products, and in many cases it is desirable to minimize, or at least to be able to control, the levels of
