Magnesium alloy forgings can be said to be the dark horse in the industry. Magnesium alloy has the advantages of low density, high specific strength, good corrosion resistance, and good machinability and plasticity, which is suitable for various processing methods, among which forging is a common processing method. High strength and high precision magnesium alloy forgings can be obtained by forging. Compared with other common metal materials, such as aluminum alloy and steel, magnesium alloy has a lighter weight, which makes it in aerospace, automobile manufacturing, electronic equipment and other fields have a wide range of applications. At the same time, magnesium alloy also has excellent thermal conductivity and can effectively heat dissipation, so it has been widely used in some occasions that need heat dissipation. However, magnesium alloy forgings face some challenges in the manufacturing process, such as easy oxidation, poor plasticity and so on. In order to overcome these problems, it is necessary to take a series of process measures, such as reasonable alloy design, optimized heat treatment process, etc. With the continuous progress of technology, the quality of magnesium alloy forgings continues to improve, and the application range is also expanding. In short, magnesium alloy forgings have better comprehensive performance and broad market prospects, and are gradually emerging in the industrial field.
