Compared with other non-ferrous metals, the energy required for mechanical processing of magnesium alloy products is only about 1/5 of that of steel, and no polishing is required. It has the advantages of high shock absorption, good cutting performance, high dimensional stability, not easy to deform, good heat dissipation, high corrosion resistance, and recyclability. The disadvantage is that magnesium alloy is flammable and explosive, and highly dangerous. After four years of cooperative research and development with major institutes such as the "Hefei Institutes of Material Science, Chinese Academy of Sciences" and "Bengbu University", the first magnesium alloy explosion-proof die-casting machine was successfully launched in September 2024. The project has applied for 106 patents, of which 13 national invention patents have been authorized, 5 software copyrights have been authorized, 1 design patent has been authorized, and 2 integrated circuit design layouts have been authorized. The successful development of this project has broken the past production of magnesium alloy die-casting products must purchase foreign magnesium alloy die-casting machines, saving the country a large amount of foreign exchange purchases/importing a large amount of foreign exchange sales revenue, and saving production and equipment procurement costs for enterprises: Magnesium alloy die-casting parts are widely used in: aerospace, ships, automobiles/new energy vehicles, motorcycles, 3C (computers, communications, consumer electronics), computers and other fields. When magnesium alloys are used in automobiles, aircraft and other parts, they can effectively reduce the noise caused by vibration, greatly reduce weight, and reduce fuel/electricity/natural gas consumption; when magnesium alloys are used in mobile phones, laptops, and electrical control cabinets, they can significantly enhance the product's heat dissipation capacity (can channel and eliminate the heat generated by electronic parts such as CPUs) and seismic resistance, and can effectively reduce the harm of electromagnetic radiation to the human body and the surrounding environment; magnesium alloys can be fully recycled, but due to the two major bottlenecks of technology and price, magnesium is called "noble metal": China's magnesium die-casting industry is developing rapidly. China's magnesium alloy die-casting output will increase from 281,000 tons in 2022 with a market size of 16.55 billion to 299,200 tons in 2023 with a market size of 17.52 billion. In the 20th century, aluminum alloys replaced traditional cast iron and steel castings. In the 21st century, magnesium alloys will replace aluminum die-castings and steel. It is becoming a development trend in the manufacturing industry, especially automobiles/new energy vehicles, industry, electronic communications industry, aerospace, IT, and ship and agricultural machinery manufacturing industries, making magnesium alloys the golden industrial chain of the ...
