The selection of magnesium alloy forgings has the following unique advantages: Light weight and high strength: Magnesium alloy is a lightweight metal material, its density is low, only two thirds of aluminum alloy, is a quarter of steel, so the use of magnesium alloy forgings can achieve the lightweight design of the product. Despite being light, magnesium alloys have good strength and rigidity, making them a “lightweight, high-strength” material that can reduce overall weight while maintaining strength. Excellent mechanical properties: Magnesium alloy forgings have excellent mechanical properties. Its high specific strength and stiffness make the magnesium alloy perform well in bearing capacity, tensile strength and fatigue resistance. In addition, magnesium alloys have good energy absorption capacity and excellent performance in shock and vibration applications. Good corrosion resistance: Magnesium alloy has good corrosion resistance and can maintain its stability under harsh environmental conditions. Its corrosion resistance is mainly manifested in the natural formation of a dense oxide film on the surface of the magnesium alloy, forming a protective layer to prevent further oxidation and corrosion. Good thermal and electrical conductivity: Magnesium alloy has high thermal and electrical conductivity, which can effectively conduct and disperse heat and current, and is suitable for applications requiring good thermal or electrical conductivity. Biocompatibility: Magnesium alloy forgings have outstanding advantages in the field of medical devices. Magnesium alloy has good biocompatibility, good histocompatibility with human body, will not produce toxic side effects on human body, and can reduce postoperative complications in medical device manufacturing, and improve the success rate and effect of surgery. In short, magnesium alloy forgings with its light weight, high strength, excellent mechanical properties, good corrosion resistance, thermal and electrical conductivity and biocompatibility and other unique advantages, become the ideal choice in many fields, and to achieve product lightweight, improve performance and efficiency, promote industrial upgrading and technological progress play an important role.
