Magnesium Alloy Assists Automotive Casting Industry - Dongguan Magnesium Alloy

98% of the world's demand for magnesium alloys in engineering components comes from the die-casting industry, and the vast majority of it is used in the automotive industry. The size of a car's mass has a significant impact on its energy consumption. For every 100 kg reduction in mass, fuel consumption can be reduced by 0 7 L. The density of magnesium is only 1.74 g/cm3, so magnesium based alloys are about 36% lighter than aluminum alloys, about 73% lighter than zinc alloys, and about 77% lighter than steel. Magnesium alloy is currently the lightest metal material used. The regions and countries with a high consumption of die-casting magnesium alloys in the automotive industry are mainly North America, Europe, Japan, and South Korea. The usage of die-casting magnesium alloys in these regions and countries has sharply increased in recent years. For example, in 1991, the usage of die-casting magnesium alloy was only 2 40000 tons, but by 1997 it had increased to 6 40000 tons, and 80% of the die-casting magnesium alloy is used to produce automotive parts.

The attempt to reduce weight by using magnesium alloy to make automotive structural components has been ongoing for nearly 70 years, but the call for weight reduction in automobiles has never been as strong as it is now. Of course, people can seek solutions through fuel management systems and other means, but among these methods, the efforts to lighten automobiles will be crucial. Therefore, the die-casting process performance of magnesium alloys plays a decisive role in the development of their industrial applications.

It has been proven that magnesium alloy is a very suitable metal material for die-casting, which can be both cold and hot chamber die-casting. The wall thickness of magnesium alloy die-casting parts can currently reach 1 0-2 At the technical level of 0mm, the main advantages of its products are good quality, high efficiency, and low processing costs.

In the next five years, the world will accelerate the development of magnesium alloy automotive parts, such as instrument dials, seat frames, gearbox housings, steering components, cylinder heads, suction branch pipes, door frames, large exterior components, engine housings, support columns, etc. Obviously, in the global development of automotive lightweight, the Chinese automotive industry will not just wait and see.
