Domestic enterprises now mainly produces magnesium alloy die casting, magnesium alloy parts products rarely involves light weight, shock-absorbing performance, casting performance, known as the "cars lightweight material of choice." However, few domestic enterprises can achieve the production of magnesium alloy auto parts industry required standard products, most made of magnesium metal for export.

    2011 is being organized by the Shanghai Auto Show, car lighter into a hot spot visitors. With the formation of apparent contrast, alternative alloy materials - known as the "cars lightweight material of choice" of magnesium alloys is in China's "freeze."

    Vice President of Shanghai Jiao Tong University, alloys Wenjiang April 19 experts at an industry forum to invoke a set of data that the 2001 primary magnesium production in China accounts for 39% of global output, to the already increased in 2009 to 88%.

    Ting Wen-chiang another set of data provided, the current use of magnesium alloys per vehicle in North America 3.5kg, the European YWPASSAT and AudiA4 magnesium alloy used on each vehicle to 14kg, while the average domestic consumption per car is only 1.5kg.

    Magnesium alloy die-casting Co., Ltd. Shanghai tension group general manager, said China's auto consumption of magnesium alloys compared with foreign countries is not a small gap does exist.

    By foreign as "revolutionary metal" magnesium alloy, why be left out in the domestic application?

    Magnesium alloy light weight, shock-absorbing performance, casting performance, automated production of high capacity and tool life, dimensional stability. Ting Wen-chiang said that at present the main magnesium alloys used in the automobile gear box housing, cylinder head, dashboard, steering wheel, wheels and other automotive components, the magnesium alloy can be in the military, and other areas of application of biological materials.

    Ting Wen-chiang told the Post reporter, 25 years ago, magnesium aluminum price is 4 times, but rather with the aluminum. The main reason is the main domestic production of magnesium alloy die casting companies now present few companies able to produce magnesium alloys meet the standards required parts automotive industry products.

    Great Britain had issued securities to a study reported that when the bid was less than 1.3 Mg, Al, as a substitute for the magnesium aluminum alloy will be a large number of applications. According to April 27 China Nonferrous Metals net data, aluminum price is 17,250 yuan / ton, magnesium price is 19,450 yuan / ton, Mg, Al were lower than 1.12.

    According to the British big Securities research report, China's total reserves of magnesium resources accounted for 22.5% of the world, ranking first in the world, while China has proven reserves of 3.4 billion tons of magnesite, magnesite total reserves of the world 28.3% world's largest. With the rich reserves of dolomite, magnesite, magnesium and other magnesium and mineral resources, expanding the scale of China's magnesium industry, has now become the world's largest magnesium producer and exporter.

    China Nonferrous Metals Industry Association released data show that primary magnesium production in China in 2010 653,800 tons, close to the highest level in history. It is noteworthy that, according to China's reported disclosure of non-ferrous metals in 2010, the year China's magnesium exports amounted to 384,000 tons, compared with 2009 (23.35 tons) by 64.43%.

    April 19, Baosteel Group, Zhe Wang, chief expert meeting is expected in these sectors by 2020, cars with magnesium alloy market demand in Europe and America at 770,000 tons, and domestic demand 5 million to 10 million tons.

    According to Wang Zhe estimates, such as the global vehicle production in 2020 was 97 million, if the vehicle remains unchanged with the magnesium (10%), magnesium demand will reach 1.02 million tons, 1.64 million tons technical limits of application requirements, including plate and strip 60 million tons.

    Zhe Wang also said that domestic magnesium alloy application in automobile companies to the main casting, die casting process has been more mature, the cost fell to apply the critical point, plate and strip application technology has yet to be perfect, "magnesium plate and strip the market not mature, lower power shortage "
