the classification detail of magnesium ignot
Industrial magnesium can reach a purity of more than 99.99%, but pure magnesium itself cannot be used as a structural material. In order to enhance the performance of pure magnesium, alloying elements such as aluminum, zinc, lithium, manganese, zirconium and rare earth can be added to make magnesium alloy, which has high strength and is widely used in the field of structural materials. According to different alloying elements, magnesium alloys can be divided into five series: Mg-Al, Mg-Zn, Mg-Mn, Mg-Zr and Mg-RE. In addition, magnesium alloys can also be divided into cast magnesium alloys and deformed magnesium alloys according to their processing properties, no matter what type of magnesium alloy it is, its properties will be different after different heat treatments.
Classification standards for magnesium ingots
1. Shape classification
According to the shape of magnesium ingots, they can be divided into different shape types, mainly bulk magnesium ingots, rod magnesium ingots, powdered magnesium ingots, etc.
2. Purity classification
Purity is one of the important indicators to measure the quality of magnesium ingots. According to international standards, the purity of magnesium ingots is usually divided into different grades, such as 99.9%, 99.95%, 99.99%, etc. The higher the purity, the better the quality of the magnesium ingot, and the higher the price.
3. Classification of impurity content
The impurity content is another key factor affecting the quality of magnesium ingots. Depending on the application requirements, the impurity content can be divided into different standard grades. For example, for the demanding aerospace sector, the impurity content needs to be less than 0.005%.
