Mobile phones have become a communication tool that people, especially the staff, cannot do without the staff. There are almost one person, some people even have two or three or more, but their bodies are made of materials, not everyone. Clear two Chu.

In the smartphones produced by the world's three major mobile phone production groups (American Apple, South Korea's Samsung, and China's Huawei), they are made of aluminum, titanium, and magnesium. Titanium body is bright and strong, but the price is higher, the density is higher, 66.7% larger than aluminum; the density of magnesium is small, 36% lighter than aluminum, with silvery hue, but the intensity is better than aluminum. Low, corrosion resistance is far less than aluminum, and the price is more expensive than aluminum.

Therefore, aluminum is currently the best overall performance and cost-effective smartphone body material, and its recyclability and recyclability are also superior to titanium and magnesium. The aluminum, magnesium and titanium that the author says here include various alloys.

We know that the size of Apple's mobile phone - the screen size has been increased from iphone 5, giving the visual an unprecedented satisfaction, watching the mobile phone has become a wonderful enjoyment, has now been added to 140mm (5.5 inches). However, the fuselage material of the initial large-screen mobile phone has not been improved synchronously, and the thickness of the body is still thinning. As a result, the body of the iphone mobile phone is deformed by an external force, and even becomes curved, and sometimes it will be put down with carelessness. The baby's mobile phone is bent, and in some cases, the screen may be beaten and broken. This situation has not been fundamentally changed until the launch of iphone 6 plus. Apple is under increasing market pressure and users are increasingly complaining.
