In order to make the notebook thinner and lighter, various manufacturers have made no less effort on materials than on performance upgrades. For the laptop material, it needs to be strong enough to protect the fragile screen and motherboard. It also needs to be light enough to take care of the equally fragile shoulders and lumbar spine.
The first-generation MacBook Air is probably the first time Apple tried aluminum alloy CNC integrated molding process on a computer, and then officially announced this process on the second-generation MacBook Pro. Until today, almost all Apple products are combined with aluminum alloy and CNC technology.
Another company that has experience in aluminum alloy processing technology on notebooks is Dell. In its XPS product line, the main body material has always been aluminum alloy: 6xxx aluminum like Al 6061 t651 with CNC integrated molding technology.
The same is true for HP's Spectre and Asus's high-end lightweight ZenBook, all of which have a preference for aluminum alloys. Compared with plastic, aluminum alloy is undoubtedly a more suitable material for light and thin notebooks. Basically, it has all the advantages of plastic, even stronger and more textured.
The common alloy for laptop are 6xxx and 5xxx aluminum. Its specific gravity is 2.70 g/cm3, which is naturally much lighter than steel with a specific gravity of about 7.8g/cm3. Magnesium is lighter than aluminum. Using magnesium as an alloy substrate can achieve a lighter weight under a certain strength.
There are many different forms of metal surface treatment, such as: sandblasting (to form a matte pearl silver surface), polishing (to form a mirror surface), embossing (to suppress various textures), electroplating (covering a layer of other metal), spraying ( covering it with non-metallic coating), brushing,etc.
Compared with other surface treatments, brushing can make the metal surface obtain a non-mirror-like metallic luster, which has a very strong decorative effect like a silk surface. so the current drawing treatment has gained more and more recognition.
In the face of various 3C digital products that have emerged in recent years, the application of brushing process is becoming more and more popular, such as notebook panels, keyboard boards, mobile phone panels, LCD frame surfaces, battery covers, and cameras.
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.
