Some time ago as for IPHONE 6 out of the paint door event causing a sensation among consumers: part of the iPhone6S mobile phone used for some time after the "drop paint", the surface random peeling spots, the overall look "rusty".
The main reason: the previous iPhone6 has also used the grade 6 series of
aluminum alloy sheet as the phone shell, 6 series of aluminum alloy to magnesium and silicon as the main alloying elements, is currently the most widely used alloy.,the main alloy of aluminum alloy elements are magnesium and silicon, alloy content is low, anodic oxidation yield is high, strong adhesion of oxide film , To protect the aluminum alloy material from corrosion, so no such "rust" situation occurred. But the biggest drawback of the 6 series aluminum alloy is the low strength, so the phone is easy to be bent, bending the situation, Apple had to choose a higher strength of the 7000 series of aircraft grade aluminum.
According to the different alloy materials aluminium alloy sheet can be divided into 1 to 9 series of aluminum alloy, each series of specific models are generally named for the four digits, such as 6061,
7075 aluminium alloy, etc.
Why aluminium alloy sheet are widely used for Iphone material nowdays.it is determinted by aluminium alloys characteristic.
Compared with the low-key stainless steel, aluminum alloy material is easier to handle high-end, beautiful, shiny feeling. Second, the aluminum alloy material is very light, the proportion of only one-third of stainless steel, that is the same volume of stainless steel mobile phone, the material is almost three times the weight of aluminum. This is why iPhone5 is so much lighter than iPhone4S. Third, scratch-resistant, aluminum alloy material is not in the top of the strength, but the surface hardness has reached the sapphire level, so the use of aluminum alloy phone may have bumps close, but few scratches. Fourth, the aluminum alloy dyed strong, because of the use of aluminum, Iphone and other mobile phones to have our so-called "earth Hao gold", "high-end gray" and other colors.
In addition, aluminum alloy materials and have high temperature, leaving no fingerprints, anti-static, environmentally friendly non-toxic and so on.
