"It was bone" is very light, but still can have a strong "skill". It is one of the most abundant elements on earth, humans do not know how to play to their strengths. Today morning lecture 100th Oriental Science and Technology Forum, the focus is known as "green engineering material of magnesium alloy in twenty-first Century". Experts agree that Chinese as the world's largest magnesium production and export country, should grasp the application of magnesium alloy technology development more high-end, "China manufacturing" to seize the high ground in related fields.
Magnesium has many advantages: the density of the pure magnesium aluminum 2/3, steel 1/4, to achieve the same strength and stiffness, the use of magnesium material than aluminum and steel light. At the same time, thermal conductivity of magnesium is good, easy processing and easy recovery, and damping, electromagnetic shielding and other functions. Magnesium alloy is the lightest metal structure in industrial applications. If you can use a large number of magnesium alloy to replace the materials Aluminum Alloy and steel structure, can effectively for the aircraft, automotive, residential buildings, weight loss. For mobile phone and other electronic products to "wear" magnesium alloy coat, without conductive treatment can obtain excellent shielding effect, improve work efficiency and service life.
The development of application of magnesium alloy in China is seriously lagging behind, above 80% as primary raw material export at a low price. Experts, automotive, rail transportation and aircraft manufacturing industry in Shanghai will be the focus of future development of magnesium alloy industry, light, environmental protection and safety is expected to seize the high ground in international competition in Shanghai. To maximize the use of magnesium alloy parts with light weight and high strength, the fastest speed related to the development of core technology, Shanghai can become a research and development, production and application of magnesium alloy in China base.
