Hot Rolled Magnesium Alloy Plate is a sheet made of magnesium alloy as the base material by hot rolling process. Common magnesium alloy hot rolled plate grades are AZ31, AZ61, AZ80, AM50A and so on. Rolling is one of the methods to make magnesium alloy, in addition, forging, casting, extrusion can also make magnesium alloy, each has its own advantages and disadvantages. The following is a detailed introduction to hot rolled magnesium alloys.
Performance Characteristics of Hot Rolled Magnesium Alloy Plate
1. Mechanical properties: high strength and good plasticity, strength varies according to alloy composition and rolling process, such as AZ31 hot rolled plate tensile strength up to 220 - 290MPa, yield strength 140 - 200MPa, elongation 15 - 25%, can withstand a certain degree of external forces to meet the requirements of use. And Forged Magnesium Alloy Plate and Casting Magnesium Alloy Plate can not achieve such high performance.
2. Processing performance: hot rolling can improve the internal organisation of magnesium alloy, so that it has good processing performance, can be made into various types of parts through stamping, bending, welding and other secondary processing, such as automotive parts, electronic equipment shells.
3. Surface quality: the surface of hot rolled plate is relatively flat, but compared with cold rolled plate, the surface roughness is higher, some application scenarios need to carry out subsequent surface treatment, such as grinding, polishing, painting, etc., to improve the surface quality and appearance.
4. Cost-effectiveness: Compared with cold rolling and other processes, hot rolling has high productivity and low cost, which is suitable for mass production.
Application Fields of Hot Rolled Magnesium Alloy Plate
1. Aerospace: used in the manufacture of aircraft wings, fuselage frames and other components, the use of its lightweight characteristics to reduce aircraft weight, improve fuel efficiency and flight performance, high strength to ensure structural safety.
2. Automotive industry: to make automotive hoods, doors, seat frames, etc., to reduce the weight of automobiles, achieve lightweight, improve fuel economy and handling performance.
3. Electronic equipment: as a laptop, tablet PC, mobile phone and other shell materials, not only to provide a certain degree of strength to protect the internal components, but also to achieve the thin and light equipment, to meet the consumer's pursuit of portability.
4. Architectural decoration: Used for building curtain walls, interior decorative panels, etc., its unique metal texture and colour can enhance the aesthetics of the building, and lightweight and easy to install.
