Dongguan Sheng Cade material resistant magnesium alloy magnesium alloy Mg-Al-Si (AS) is a die-cast magnesium alloy alloy developed by Volkswagen AG. When 175 cC, creep strength AS41 alloy AZ91 and AM60 alloys significantly higher. However, AS based alloys during solidification due to the formation of coarse characters like Mg2Si phase, damage to the casting and mechanical properties. Study found that the production of magnesium alloy die-casting process, the addition of trace Ca morphological characters can improve the shape MgaSi phase Mg2Si particles refined magnesium alloy die casting parts, to improve the organization and performance of AS series of magnesium alloy. Dongguan Sheng Cade magnesium alloy material present, China's primary magnesium production in the world. 2000 national production of about 200000t, more than 80 percent as the primary raw material exports cheap magnesium alloy die manufacturing, domestic consumption is about 20000t. Only 2000t for Santana gearbox housing, the rest are used as general purpose alloy preparation and so on. Because of the technical equipment and the development and application of magnesium alloys is lagging behind, the domestic magnesium industry showed serious structural contradictions. Our non-ferrous metal die-cast magnesium alloy has a considerable base die casting, casting plant points and now has a total of about 3000 related businesses, about 20 die-casting machine factory, with an annual casting 300000t. Which accounted for 75.5% of aluminum die casting, magnesium die castings accounted for only about 1%. Shanghai Automobile Accessory Co., Ltd. Shanghai Santana production of magnesium alloy die-casting gearbox casing has a long history. Magnesium alloy die processors, Cade Sheng (certified), magnesium alloy die-casting process is provided by Cade Sheng Technology Co., Ltd. of Dongguan City. Sheng Technology Co., Ltd., Dongguan City, Cade (www.kadesn.com) is Dongguan, the other leaders, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs.
