Recently, some netizens have bought their iphone6s on the back of the painting to the internet has caused a lot of users resonance. Think the original iphone6s just on line because the problem of easy to bend the material replaced by a new 7000 series of aluminum, although this makes the hardness greatly increased but there is a fatal problem is the oxidation of serious.
Although it may not be visible when you buy it, it is now estimated that many of the first buyers of iphone6s have experienced this.
Apple iphone6s rose gold drop Paint Solution:
From the current point of view this may be due to the 7000 series of aluminum alloy itself caused by the problem. Compared to the 6000 series aluminum alloy, 7000 series of aluminum alloy because in the production of more zinc, resulting in poor corrosion resistance, very easy to oxidize, surface adhesion compared to 6000 series aluminum alloy is also worse, this may be the cause of this situation.
If you want to avoid this situation, try to avoid the use of damp environment is the best way to solve.
Iphone6s Why the back is easy to oxidize:
It is understood that 7000 aluminum can be called industrial aluminum alloy in the highest strength of the class, its strength even reached what we call the steel bar (industry called A3 Steel) about 2/3, wear resistance is also strong, but there is a disadvantage is that because of the addition of more zinc, resulting in poor corrosion resistance, very easy to oxidize, Surface adhesion is also less than 6000 aluminum, but it is said that the Apple has been through the thickened antioxidant layer to solve the problem, but from the facts, may be quality control or other aspects of the problem, or some iphone6s use for a long time will encounter the phenomenon of oxidation paint.
