where can use the magnesium alloy

  Magnesium alloy has the characteristics of low density (the density of pure magnesium is 1.749/cm3, about 64% of aluminum, 25% of zinc and 20% of steel) and high specific strength.In recent years, based on the advantages of magnesium alloys, some material researchers have developed a series of magnesium alloy plates with high strength and excellent room temperature forming properties, such as AZ31 and MG-ZNRE series of magnesium alloys.Its tensile strength can reach more than 200MPa, elongation can reach more than 20%.This fully indicates that magnesium alloy can not only meet the strength requirements of high-rise building curtain wall, but also meet the requirements of specific building to sheet forming performance.Therefore, the use of magnesium alloy materials in building curtain walls has great development potential.

  Although magnesium alloy has the strength comparable to aluminum alloy, its weight is only about 64% of the same volume of aluminum alloy, and it has good room temperature molding performance, making it possible for magnesium alloy to be used in the field of metal curtain wall.But there are some problems that need to be solved.

  As the panel material used in the building curtain wall, the excellent thermal conductivity of magnesium alloy has become the bottleneck problem restricting the use and development of magnesium alloy curtain wall.The curtain wall material with good thermal conductivity is neither economical nor energy-saving for the building itself.

  Magnesium alloy plate is relatively light, which can reduce the amount and strength of keel and connector, but for high-rise and super high-rise buildings, it is necessary to ensure the deformation resistance of their curtain wall system.

  In the external structure of the building, in order to reduce the load bearing of steel keel, through the development of light building curtain wall materials, reduce the consumption of steel keel, so as to achieve the purpose of effectively saving high energy consuming building materials.New concept architecture in China started late, especially in the processing technology and material research and development of complex curved metal materials compared with developed countries still have a certain gap.With the advent of the era of information explosion, designers can exchange what they need, and different designers have different innovative design concepts. However, due to the single choice of complex curved metal building decoration materials and the lag in the development of new metal curtain wall materials, designers cannot fully realize their own assumptions about buildings.
