Application of new magnesium alloy curtain wall

The types of materials used in the world's metal curtain walls are relatively single, including some aluminum composite plates, single-layer aluminum plates, stainless steel plates and painted steel plates, etc.The mechanics of metal materials and their own characteristics give the metal curtain wall a unique decorative effect.Different metal materials reflect their unique quality characteristics, such as the elegance and luxury of bronze;High strength and corrosion resistance of stainless steel;The surface color diversity of aluminum alloy, the light weight of magnesium alloy.

With the economic globalization and the proposal of China's "One Belt and one Road" development concept, the concept of energy conservation and consumption reduction has been deeply rooted in various industries, and they are all developing technologies related to energy conservation and consumption reduction and formulating sustainable development strategies.Building energy conservation mainly starts from the peripheral system of the building. 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.

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.
