Composition and Source of Magnesium Metal
The main component of metallic magnesium is magnesium (Mg), which is located in the second main group of the periodic table of elements and has an atomic number of 12. Magnesium is a light and corrosion-resistant metal, which exists in minerals, plants, seawater and volcanic magma in nature. It can be extracted and prepared by electrolysis and thermal reduction.
the characteristics and application of metallic magnesium
1. Low density: The density of magnesium is only 1.74 g/cm, which is about 2/3 of that of aluminum and 1/4 of that of steel. It can effectively reduce the weight of products and is widely used in aviation, automobiles and other fields.
2. High strength: At normal temperature and high temperature, magnesium metal has high strength, good tensile strength and yield strength, so it can be used to manufacture various metal parts.
3. Good mechanical properties: magnesium metal has good formability and machinability, and can be used for forging, casting, deep drawing and other manufacturing processes. The surface treatment methods of products are diverse, and the surface of products is smooth and beautiful.
Metal magnesium has a wide range of applications in many fields, mainly including the following aspects:
1. Aviation and aerospace field: With the continuous development of aviation and aerospace industry, magnesium metal has been widely used in this field. Such as forging dies for manufacturing titanium alloys and die-casting dies for aluminum alloys.
2. Electronic and communication fields: Metal magnesium has been widely used in this field because of its excellent electrolytic performance. Such as a touch pad of a mobile phone, a camera shell and the like.
3. Automobile field: Magnesium metal is widely used in automobile field, mainly including engine head, gearbox, frame and so on.
