Magnesium is a material of the 21st century and it began to replace plastics that have dominated the market for more than 20 years. Recently, progress has been made in magnesium alloy forming technology. The main advantage of this material is that it can be made thinner than plastic. For example, the cell phone case uses a 0.4 mm to 0.6 mm thinner magnesium alloy than 1.5 mm. In addition, among all commercial metals, magnesium alloys are the lightest, 30% lighter than aluminum, and 1/4 the thickness of steel. In addition to its light weight and its high strength, it can be deformed. This kind of metal can be used for the protection screen of electromagnetic radiation of electronic communication equipment such as mobile phones, etc. It can also meet the needs of miniaturization of mobile phones, light weight, luster, and good coloring. The most important thing is that it has no pollution of the environment and it is easily extracted from seawater.
This magnesium product can be manufactured by various methods such as hot chamber die casting, thixoforming, block forging, sheet metal forming, hydroforming, powder metallurgy, and superplastic forming. The main methods used are die casting and sheet metal forming. The sheet forming method has no surface blistering and no ripples; magnesium is flammable at high temperatures, but it can be processed safely at a temperature of 150°C to 300°C using this method; it also has high quality, no metal particles during casting and low cost Advantages: The thin-plate forming method can use existing stamping equipment to process at a temperature of 150° C. to 300° C., increasing the toughness of magnesium and reducing its strength, becoming a better deformed material, and when cooled, it can restore the normal high strength of magnesium. . In the past, magnesium was used only in aerospace high-tech. After low-cost processing with sheet metal forming, it can now be widely used in electronic consumer applications such as notebook computers, mobile phones, and computer peripherals.
