What testing items should be done for metal composition analysis? Metal composition analysis refers to the use of large-scale analytical and testing instruments to analyze and test metal materials or products, determine their composition and content, and use it to understand the material and quality of metals. Metal composition analysis is a type of material analysis that typically uses multiple chemical and physical testing methods for qualitative and quantitative analysis to determine the formula and content of each component of metal materials.


Metal composition analysis mainly focuses on metal materials such as copper, iron, aluminum, tin, nickel, and their alloys, and the analyzed elements include main components and impurity elements. During the analysis process, detection methods such as spectral analysis, chemical analysis, energy spectrum analysis, and metallographic analysis are generally used to determine the chemical composition, mechanical properties, physical properties, and other related parameters of metal materials.


By analyzing the metal composition, one can understand the material and quality of the material, and determine whether it meets the corresponding standards and requirements. If the actual chemical composition of the raw materials, semi-finished products, and finished products provided by the supplier does not meet the protocol standards, it will become a key factor affecting the final performance of the product. Therefore, metal composition analysis is of great significance for industrial production, quality control, material research and development, and other fields.


Metal composition analysis mainly involves the detection of the following items:

1. Chemical composition analysis: This is the main part of metal composition analysis, which includes the analysis of various elements in metal materials, such as carbon, silicon, manganese, phosphorus, sulfur, nickel, chromium, molybdenum, copper, vanadium, titanium, tungsten, lead, niobium, mercury, tin, cadmium, antimony, aluminum, magnesium, iron, zinc, nitrogen, hydrogen, oxygen, etc.

2. Metallographic testing: This includes observation of the microstructure and surface morphology of metal materials, such as non-metallic inclusions, macrostructure, grain size, fracture inspection, etc.

3. Mechanical performance testing: This includes testing various mechanical properties of metal materials, such as tensile test, compression test, shear test, torsion test, bending test, impact test, as well as hardness tests such as Rockwell hardness test, Brinell hardness test, and Vickers hardness test.

4. Non destructive testing and material certification: Through advanced testing methods such as X-ray fluorescence spectroscopy, mass spectrometry, ion chromatography, etc., non-destructive testing is conducted on metal materials to determine whether there are any internal defects. At the same time, it is also necessary to prove the material of metal materials to ensure that they comply with corresponding standards and requirements.
