For days, some users have come to us complaining about (not only in Spain), the low resistance of a 3G iPhone scratches. What is promised debt, so I collated all that I have been reading, watching and less on this issue. I hope you will help.
What material is made of the rear?
A few weeks ago was elucubró about the possibility that the 3G iPhone has the back cover made of zirconium (Zr), a metal like steel, very high resistance. These rumors were based on a patent Apple, which contained the following:
22. A portable computing device capable of wireless communications, the portable computing device comprising: an enclosure that Surrounds and Protects the internal operational components of the portable computing device, the enclosure including a structural wall formed from a material other than plastic that permits wireless communications therethrough; disposer and an internal antenna inside the enclosure.
23. The portable computing device as recite in claim 22 wherein the portable computing device is capable of radio frequency communications and wherein the structural wall is formed from a ceramic material that is radio-transparent.
n short, was patented (USA is patented in all, although the term "patent" is a little different from the European continentla) a portable device with communication skills inalhámbricas. Such a device would be covered by a shell made of a plastic material that allows communications inalhámbricas. In paragraph 23 which defines the ceramic material does not prevent the arrival of radio waves. In the 14 states that such material is zirconium, although the zirconium is a metal, ceramic could be made to any treatment (ceramics is a material, but also a process of finishing or treatment-the truth is that I do not know much chemistry -). Since iFixit.com, which cleared for the first time a 3G iPhone and posted on the internet, stating that the case could be ABS plastic (perhaps with an alloy PVC). Let's see what the zirconium and what the ABS (wikipedia): Zirconium: It is a hard metal, corrosion resistant, similar to steel. It is used primarily in nuclear reactors (due to its low section of neutron capture) and to be part of an alloy with high resistance to corrosion. It is lighter than steel with a hardness similar to that of copper. Mohs 6511 kg/m3 density. Dureza 5. His toughness is not very high, but its resistance to shock
ABS Plastic: Plastic highly resistant to impact (strokes) is widely used in automotive and other uses both industrial and household. It is an amorphous thermoplastic. The most important feature of ABS is their great tenacity, even at low temperature (remains steadfast to -40 C). It is also hard and rigid; acceptable chemical resistance, low water absorption, therefore good dimensional stability, high resistance to abrasion; is coated with a layer of metal with ease. The ABS can, in one of its variants, chromium by electrolysis giving different baths of metal to which it is receptive. (As published on Wikipedia, the ABS is used to make the LEGO bricks). Further details on its membership here. I do not know what kind of process or could have finished ceramic materials. My opinion is that the rear should be of some metal alloy, therefore Zirconium + slightly, while the display will be some type of ABS, ... but I'm contradicting with what Steve Jobs said: "It's got to full plastic back. "It will be difficult to determine the material until someone makes scientific evidence. In fact it is not as important if not the material that holds.
So much endures?
Either way, as publicábamos a month ago, the back cover withstood torture of the crusher of the people of Will it Blend, which means that it is incredibly resilient to shocks. Meanwhile, many users are complaining about the little resistance to scratching of the case (technically, its hardness). Especially in that part of the apple. Elaborate a bit on Youtube, I found some evidence of resistance (not suitable for cardiac imaging). The video is more interesting in this Macworld.
The editor manages to scratch the block from the rear (and in fact was a bit ensaña with it) but barely scratch the rest of the carcass. Specifically, the screen must have a hardness greater than that of aluminum, and perhaps to the steel, because it fails to rayarla or with the keys or with a clip. That toughness translates into a lower resistance to shocks, as we see in the different falls. The iPhone what happens quite wrong and finally he does not like anything you hit a motorcycle. (Obviaré regarding the tightness of the 3G iPhone, as it is not my intention tirarme to the pool with him.) In this torture, for the iPhone and to our eyes, each will draw its conclusions. I leave with you is also a video advertising, with no commercial intentions, if not for that do not lead to cheating. IS A FAKE. The scratching of the iPhone on the left are not real (as we have seen in the video of Macworld).
My conclusions
Personally, after seeing these videos, I've stopped using my silicone casing (Macally). Others may take a contrary decision. The iPhone 3G holds enough blows and scratches. Much more than I expected. At the moment I have used my own 50% of the time with housing and 50% undecided. You do not have any penalties to hatched, and these are concentrated in the apple. Curiously, some scratched off with a rag and a little mist. Perhaps there are other gadgets more resistant, such as the PSP, but there are other much more prone to deteriorate. In my opinion we give him the striped more attention to the iPhone 3G than those of other gadgets, that's why I stopped looking at it and the only thing I do to protect it is not put it in his pocket for his keys. Finally, to contradict a bit, to encourage and enrich the debate, I leave with you a video with a first-generation iPhone a little scratched.
PS: Of course, rectificaré any misinformation and modify my views on the basis of scientific parameters or other parameters random. All comments are welcome.
