Magnesium alloy and aluminum alloy belong to light engineering metal materials, compared to other gold, they all have "a lighter miyoshi" the characteristics of high --, light weight, high specific strength, damping and cutting good workability, good thermal conductivity and good vibration reduction, and easy to recycle, can satisfy the electrical home appliances, communication device is highly integrated and frivolous miniaturization requirement. Therefore, in the vast and highly competitive notebook market, many manufacturers have developed and launched notebooks characterized by "magnesium alloy shell and aluminum alloy shell", which are increasingly favored by users with mobile application needs by virtue of their lightweight portability, low cost, impact resistance, good heat dissipation and other advantages. What are the differences between the properties of magnesium alloy and aluminum alloy? Which is better? I believe that many users are still confused about this. Therefore, the author compares some mechanical property data of the two, hoping to solve these puzzles.
Magnesium alloy, the specific gravity value is two thirds of aluminum alloy, the thermal conductivity is half of aluminum alloy, the elastic modulus, tensile strength is lower, the elongation rate, the specific strength is higher, the melting point of the two is similar. Both have high technical requirements for the production of bottlenecks. Compared with the aluminum alloy die casting, the quality and yield stability of magnesium alloy die casting is poor and the rejection rate is high, which leads to the higher price of magnesium alloy products.
In the notebook market, magnesium alloy notebook and aluminum alloy notebook have their own advantages in terms of their shell materials: the former has lighter weight and greater strength for the same volume; The latter has more advantages in heat dissipation, tensile and shock resistance and price cost.
Magnesium-aluminum alloys, whose main element is aluminum, are fortified with small amounts of magnesium or other metallic materials. Magnesium aluminum alloy with light weight and easy to heat, in the pursuit of ultra-thin models used quite a lot, and easy to add cost is moderate.
Many businesses like magnesium alloy shell as a selling point, emphasizing "aircraft materials" and so on, and therefore, consumers gradually recognized this material shell of the notebook, and regard it as a standard to buy notebooks. Because of the excellent performance of magnesium aluminum alloy, it has become the best material for the mainstream notebook shell, the notebook of the first-line factory in China almost all use magnesium aluminum alloy material, at the same time, Samsung of South Korea, NEC of Japan and so on, are also in use.
The color of the notebook shell is also gradually changing, no longer a single, but to seek the cooperation between colors. The silver magnesium aluminum alloy outer shell can make the product more luxurious, beautiful, and easy to color, can be transformed into a personalized powder blue and pink through the surface treatment process, for the notebook computer color, which is ABS engineering plastics and carbon fiber to be mentioned below can not be compared.
