Description

technical field [0001] The invention relates to the technical field of alloy component analysis, in particular to a method for determining chromium, lead and tin in aluminum alloys by using wavelength dispersive X-ray fluorescence spectrometry. Background technique [0002] Aluminum is an extremely abundant metal element on the earth, and its reserves rank first among metals. By the end of the 19th century, with the development of the electrolytic aluminum industry, aluminum became a competitive metal in engineering applications and became all the rage. The development of the three important industries of aviation, construction and automobile requires the material properties to have the unique properties of aluminum and its alloys. Aluminum is used commercially for items such as mirror frames, door signs and serving trays. Aluminum cooking utensils have also become a commodity in the market. Aluminum has now been developed into a material with a variety of uses, wide enou...
