[China Aluminum Industry Network] What has changed in the shell material of the iPhone in 10 years? What is the role of aluminum in it?
When it comes to feelings, the first thing I think of is not the iPhone but the Nokia.
The still ringing mobile phone ringtones;
The pair of hands
Even a black-and-white screen game of snakes;
All bear the youth and memories of generations.
How many people use Nokia today? Just on January 5 this year, the Nokia 6G has just released, this phone uses the 6000 series aluminum alloy material, CNC integral molding technology, and after 11 hours of two-color anodizing and grinding, and the fuselage structure specially The added sheet metal frame improves the overall structural strength. In terms of materials, structure, and technology, Nokia's sentiment has gradually begun to fall into the realm of product production.
However, on the basis of the shell material alone, the changes in the material of the Iphone case over the past decade have really brought his own feelings about the metal to be excellent. Small aluminum can intercept several representative products:
One, iPhone 4
Material Keywords: stainless steel, tempered glass
This special toughened glass is 30 times harder than ordinary plastics, 20 times tougher than plastics, and strong in impact resistance. It can also be used in helicopter windshields and other fields. Stainless steel frame is very strong, the combination of both makes this phone full of heavy sense, has become a generation of God machine!
Second, iPhone 5/5s
Material Keywords: Anodized aluminum alloy shell, glass
The anodized aluminum alloy covers the entire frame and most of the back cover, and the top and bottom back cover are glass. It is also from this phone, starting with a large number of metal mobile phones. Since then, domestic mobile phones have followed suit, and aluminum has been widely used in the manufacture of mobile phone housings. Remember the word "local gold"? It is also because the addition of other non-ferrous metals to aluminum has become a sought-after color for a large number of consumers. In fact, the aluminum processing technology is very complicated and relatively high cost.
Third, iPhone 6s/iPhone 7
Material Keywords: Ion-X glass, 7000 series aluminum metal
Materials from 6 to 7 have also undergone changes from 6000 series aluminum alloys to 7000 series aluminum alloys. The hardness is 60% higher than that of ordinary aluminum materials, and the density reaches one-third of that of stainless steel, which means that it is lighter and harder. Successfully solved the "bending door." The processing technology uses a special compound to rotate the 3D polished bright black shell, thereby removing the flaws, so that the body material to achieve seamless convergence, the surface is more smooth and bright.
Fourth, iPhone 8/X
Material Keywords: Aerospace aluminum frame, stainless steel, double glass design
From the mobile phone casing material, today Apple still maintains the feeling of metal + glass, and has always forgotten to constantly strive for perfection in the hardness, texture and appearance of the mobile phone. Aviation aluminum is a high-performance aluminum material and has high requirements for strength, hardness, toughness, fatigue resistance and plasticity. At the Aluminum Industry Exhibition in July last year, we held a professional forum on the topic “Aluminum Alloys in the Appearance Requirements and Applications of Consumer Electronics Productsâ€. We conducted in-depth discussions on materials, processing technologies and applications and obtained TCL, Xiaomi, and Huawei. It is highly recognized by professional visitors.
In the era of high cell phone homogeneity, maintaining high quality, good reputation, and constantly satisfying users' new needs is the only way to put the feelings into practice. This is exactly what Aluminium Industry Exhibition has been pursuing. In 2018, we will march forward to show the frontier materials applications, technologies and processing technologies in the field of consumer electronics and white goods.
