There are many types of notebook shell materials, but the most popular one is metal material. There are two reasons: one is that the metal shell has high strength and strong impact resistance and it is relatively light and has a unique texture and luster.
On the other hand, due to the relatively high cost of metal materials, they were used in high-end notebooks in the early days. Therefore, in the hearts of many users, metal casings are a symbol of high-end products.
5XXX Aluminum: Strong anti-rust performance and high strength
It is also known as Al-Mg alloy. It was first used by Apple MacBook shells, and later used on various notebooks. Its main alloys are Aluminum and magnesium. 94% of the composition is aluminum, magnesium only occupies 5%, and the remaining chromium, iron and other elements add up to 1%.
Due to the addition of a variety of elements, compared with pure aluminum, aluminum-magnesium alloys have a significant improvement in chemical stability. It is not easy to rust while is easy to process. In addition, the aluminum-magnesium alloy has a major advantage in that the cost appearance does not require any beautification, and its outstanding metallic luster is enough to attract customers.
Mg-Al alloy: A more lightweight choice
For the Al-mg alloy, aluminum has an absolute advantage in percentage, while magnesium is the protagonist in magnesium-aluminum alloys. The content of magnesium in magnesium-aluminum alloy is as high as 90%. In the remaining 10%, there are 9% aluminum and 1% zinc. The remaining manganese, silicon, iron and other elements are almost negligible.
Due to the change of composition, the performance of magnesium-aluminum alloy and aluminum-magnesium alloy like 5052 aluminum is completely different. Although magnesium-aluminum alloys are not bad in strength, their ductility is much worse than that of aluminum-magnesium alloys,so manufacturers can only use casting. At the same time, it is significantly worse than aluminum-magnesium alloy in the texture and luster
With the development of dozens of years, we, Haomei Aluminum has solid base to provide clean aluminum material for the high-end applications including lithium-ion battery, lightweight automobile body, 3c products, aluminum brazing and other special uses.
