Metal composition analysis and testing is a technology that determines the element composition and content of metal materials by chemical, physical or instrumental means. It plays an important role in industry, scientific research, quality control and environmental protection. The following are its main functions:
1. Quality control and compliance verification
- Ensure material performance: The mechanical properties of metals (such as strength, hardness, corrosion resistance) are directly affected by the composition. By analyzing the composition, it can be verified whether the material meets industry standards (such as GB, ASTM, ISO, etc.).
- Production process monitoring: Real-time detection of composition during metallurgy, casting, welding and other processes to avoid product defects due to composition deviation.
- Supply chain management: Verify whether the metal materials provided by raw material suppliers meet the standards and reduce procurement risks.
2. Material identification and classification
- Distinguish metal types: Quickly identify specific grades such as stainless steel (such as 304, 316), aluminum alloys (such as 6061, 7075), etc. to avoid mixing.
- Authenticity identification: used for purity detection of jewelry, precious metals (gold, silver), or material analysis of antique metal objects.
3. Failure analysis and problem diagnosis
- Accident cause tracing: When mechanical parts break or equipment corrodes, analyze whether the composition is abnormal (such as excessive impurity elements, incorrect alloy ratio), and determine whether it is a material problem.
- Process improvement: Optimize process parameters such as heat treatment and surface treatment through composition analysis.
4. Research and development and optimization of new materials
- Alloy design: Develop high-strength, high-temperature resistant or lightweight new materials by adjusting the element ratio (such as adding rare earth elements to improve performance).
- Reverse engineering: Analyze the composition of competing materials and assist in independent research and development.
5. Environmental protection and safety compliance
- Harmful element detection: Ensure that materials comply with environmental regulations (such as RoHS, REACH), and detect toxic substances such as lead, cadmium, and mercury.
- Waste recycling: Identify the composition when sorting scrap metal to improve resource reuse efficiency.
6. Cost control
- Evaluation of alternative materials: Select more economical alloy composition to reduce production costs while meeting performance requirements.
- Reduce waste: avoid batch scrapping due to substandard ingredients.
Common detection technologies
- Spectral analysis: such as spark direct reading spectroscopy (OES), X-ray fluorescence spectroscopy (XRF) rapid non-destructive detection.
- Chemical analysis: wet titration, ICP-OES (inductively coupled plasma emission spectroscopy) high-precision quantification.
- Other methods: scanning electron microscope-energy spectrum (SEM-EDS), carbon and sulfur analyzer, etc.
Summary
Metal composition analysis and detection is a key technology to ensure product quality, optimize material performance, and meet regulatory requirements. It runs through the entire life cycle of material production, processing, application and recycling, and plays an important supporting role in industrial development and technological innovation.
