Magnesium alloy forging is a kind of metal products with excellent properties, which can provide many aspects of competitiveness for products. First, magnesium alloy forgings have excellent lightweight characteristics. The density of magnesium alloy is relatively low, and the specific gravity is about twice that of aluminum alloy, so the weight of the product can be greatly reduced. In automotive, aerospace and electronics, lightweight design is an important trend, and the use of magnesium forgings can significantly reduce product weight, improve energy efficiency, and reduce environmental load. Secondly, magnesium alloy forgings have good mechanical properties. Magnesium alloys exhibit excellent strength and rigidity, while maintaining high plasticity and toughness, and have good impact resistance. This enables magnesium alloy forgings to perform well under dynamic loads and vibration environments, improving product life and reliability. In addition, magnesium alloy forgings have excellent corrosion resistance. Magnesium alloy has the characteristics of self-corrosion protection, even without surface coating treatment, it can maintain good corrosion resistance in most environments. This makes magnesium alloy forgings have a wide application prospect in some humid, acid and alkali harsh working environment. In addition, magnesium alloy forgings also have excellent thermal conductivity and electromagnetic shielding properties, providing a feasible solution for some special areas of product design and performance requirements. In short, magnesium alloy forgings, as a key component of the product, can significantly enhance the competitiveness of the product by providing advantages such as light weight, high strength and good corrosion resistance. However, it is also necessary to pay attention to the cost, surface treatment and manufacturing process of magnesium alloy forgings, and consider multiple factors in practical applications to achieve the best cost performance and market competitiveness.
