Core tip: the design of digital products by the user, and the material is also a key element. Relatively speaking, the most comprehensive metal materials, engineering plastics, the most popular low, glass material is more beautiful.

Metal
Metals have gradually become the most common material on mobile phones, tablets and laptops, but also has a large number of branches. The most common is the aluminum alloy, such as the use of iPhone 6000 series of 6 aluminum alloy, the main components include aluminum, magnesium and silicon, compared to the early aluminum, magnesium material is more robust and durable. However, the introduction of iPhone 6 also occurred in the famous bending phenomenon, of course, this is not entirely the problem of 6000 aluminum, because the phone design is too thin. So in 6S iPhone, apple switched to the 7000 series of aluminum, its strength is higher, in many of the stress test will not bend.
Notebook, the more common metal material is CNC aluminum, which is one of the aluminum block. Through the NC machine tool for a large piece of aluminum block for one of the cutting, to create a high quality chassis, structure, such products in the apple MacBook series as the representative.

Engineering plastics and carbon fiber
Engineering plastics (ABS) and digital products commonly used materials, mainly in the low-end products, the scientific name for acrylonitrile - butadiene - styrene polymer. The advantage of engineering plastics is low cost, relatively light, but the thermal conductivity and texture is obviously not as good as metal.
Obviously, the general engineering plastics is the cheapest, the most poor texture material, but the lowest cost. Whether it is a mobile phone or a notebook, it is not the most ideal. Carbon fiber is an upgraded version of the class of plastic materials, the application effect in the notebook area is still good.
Metal is clearly the first choice for many users, but also common in high-end digital products. Mobile phone, 7000 series of aluminum alloy is a good choice, the strength is higher, so if the user is concerned about the details of the material, in the purchase of products may wish to carefully investigate. Notebook, the quality of aluminum alloy material itself is about the same, the user should be concerned about the level of the process should be the manufacturer, such as MacBook series is a very good representative.

Glass
As for the glass, Samsung S6/S7 series may be the most representative of the current market products, texture outstanding, can achieve waterproof function, but the intensity is still quite worrying, it is difficult to bear the impact of the larger.
