2. Production

The production of AZ31B wrought magnesium alloy adopts mature and standardized industrial processes, focusing on process control to ensure the stability and consistency of product performance, and the production process conforms to relevant national industrial standards.

• Raw Material Control: The raw materials for production are high-purity magnesium ingots and alloying elements (aluminum, zinc, etc.), which are strictly inspected to ensure that the impurity content meets the standard requirements, laying a foundation for the stable performance of the alloy.

• Smelting & Casting: The smelting process adopts professional equipment and processes to accurately control the temperature, time and alloy composition ratio, avoid oxidation and impurity mixing, and cast into qualified ingots with uniform structure and stable performance.

• Wrought Processing: Through hot rolling, cold rolling, extrusion and other wrought processing technologies, the ingots are processed into finished products of different forms. The processing parameters (temperature, speed, deformation) are strictly controlled to improve the structure density and mechanical properties of the alloy, ensuring that the product performance meets the application requirements.

• Quality Inspection: Each link of the production process is equipped with strict quality inspection, including chemical composition detection, mechanical performance test, dimensional precision detection and surface quality inspection. Unqualified products are eliminated in time to ensure that the delivered products meet the standard requirements.
