Metal material detection

The scope of metal material testing involves mechanical performance testing, chemical composition analysis, metallographic analysis, precision dimensional measurement, non-destructive testing, corrosion resistance testing and environmental simulation testing of ferrous metals, non-ferrous metals, mechanical equipment and parts. Metal material composition analysis items
1. Test items include: physical properties and chemical composition testing, identification of unknown brands, grade determination of stainless steel, non-destructive testing of materials and material certification
2. Metal composition analysis, elements Testing, five major element tests and full elemental analysis. Provides brand identification services and stainless steel grade determination services. The five elements usually refer to the manganese, phosphorus, silicon, carbon, and sulfur elements present in steel. They are the most important and basic elements in steel. They distinguish the grades and quality of ordinary steel. Their content directly affects the mechanical properties of steel. Metal element analysis | Metal composition analysis | Alloy composition analysis Ray fluorescence spectrometry test method and corresponding characteristics Ray fluorescence spectrometry After the sample is excited by rays or other excitation sources, the atoms of the target element in the sample are excited, and the inner electrons transition and are released Emitted rays, characteristic rays of elements. Fluorescence spectroscopy. The wavelength of characteristic rays corresponds one-to-one to each element, and the intensity of characteristic rays has a quantitative relationship with the content of the element. Therefore, it can be used for qualitative and quantitative analysis of elements. The materials that can be detected include various cast iron, steel (including carbon steel, alloy steel, etc.), copper (copper alloy), aluminum (aluminum alloy), solder, zinc and zinc alloy, etc.
