Guidelines for Metal Composition Analysis
I. What is Metal Composition Analysis?
Metal composition analysis is a testing procedure that uses chemical or physical methods to accurately determine the elemental composition and content of metallic materials. It is commonly used in areas such as material quality acceptance, production process control, product development, and quality dispute resolution.
II. Common Detection Methods
| Method Name | Scope of Application | Characteristics
| Spectroscopic Analysis (OES/ICP) | Ferrous Metals, Non-ferrous Metals | Fast, High Precision, Widest Application
| Chemical Titration Analysis | Precise Quantification of High-Content Elements | Classic Method, High Accuracy
| X-ray Fluorescence Spectroscopy (XRF) | Rapid Screening | Non-destructive Testing, Suitable for On-site Testing
| ICP-MS | Trace/Extreme Elements | Extremely Low Detection Limit
| Carbon and Sulfur Analyzer | C and S Content in Steel | Specialized Testing
III. Processing Procedure (General Steps)
1. Clarify Testing Needs
Confirm Testing Materials (Steel, Aluminum, Copper, Alloys, etc.)
Clarify the Element Scope and Precision Requirements (e.g., compliance with GB, ASTM, ISO, etc. standards)
Confirm Report Purpose (Internal Reference / Trade Settlement / Forensic Identification / ...) (Certification and Qualification)
2. Choosing a Testing Organization
Official/Authoritative Organizations: Local Entry-Exit Inspection and Quarantine Bureaus, National Steel Materials Testing Center
Third-Party Testing Organizations: Such as Dezewei Testing (CNAS Registration No.: L8083)
