You can tell the Aluminium is stronger in the 6s

    The gold plating/costing doesn't chip off, revealing silver in the scratches. Apple seems to have fixed that.

    We've all dropped our phone a couple of times, and with the 6, it was a surprise that when you dropped the phone. The scratches revealed at the gold coating on the phone was thin, and that the phone was really silver.

    That takes away from the authenticity of it, I didn't like that.

    Does that happen with real gold? What do you think about the new stronger Aluminium?

    This is not gold and is not a plating or layer on top. Anodizing is a process like rusting. Chemicals seep into the top layers of the aluminum and oxidize it. By adding certain chemicals you can change the color of the anodizing. Gold, rose gold, space grey are anodized. The silver is not, but silver has a clear coat. Others do not.

    The 7000 series aluminum anodized a bit deeper than the older 6000 series aluminum. Just the nature of the metal. This means that it will take a deeper scratch to get past the surface anodization on the 6s phones. Repeated rubbing, like a case rubbing at certain points will rub through that surface anodization. With that said, anodizing is as strong as the parent metal, because it is the parent metal.

    Isn't it the same aluminum like on the Apple Watch Sport models? Already heard stories about the black color coming off of it, but I'm not sure if it's the same thing.

    It is the same thing, some colors especially black, don't anodize as deep, and black is so different looking than silver, you see the wear more easily. Lighter colors closer to the base silver hide any wear better. Remember the black anodized iPhone 5. That had lots of reports of easily being scratched. With such a dark color, scratches and wear show up easier when it is silver underneath. And the black doesn't oxidize as deeply in first place. That's why they went to space grey, less dark.

    If you want a phone that will show the least cratches, get silver. Even when scratched the color is still the same underneath. Makes it harder to notice the scratches. Same thing as paint your walls white you see every smudge. Paint them darker color, the wall gets just as dirty, but not so easily seen.

    Even Apple can not change physical laws.

    So they did improve the gold iPhone by anodizing it deeper so you'll see less silver if dropped? That's what it looks like to me. It looks so much nicer now that it can take a few scratches and still look like its gold.

    Is it possible to go deeper? So that even if dropped the color remains the same?

    It just breaks the illusion that your phone is not really the color it is described as.

    7000 series aluminium is harder and more durable so in turn the anodised layer is more durable.

    That's one of the best things about these new phones. You can drop it and it takes less damage.

    It should definitely be stronger though. I'd like to see a lot less scratches if dropped.

    My iPhone took a rather tame drop and took like -1 damage, when it really should've been 0 for such a tame drop.

    There's nicks in the corners. But they're very tame. It looks brushed and it doesn't bother me that much cosmetically.

    The 7000 series aluminum anodized deeper. It's a property of threat alloy.

    The tensile strength of 7000 series aluminum is twice that of 6000 series. You have to be careful when using a general term like stronger. It leaves too much up to interpretation, stronger in what way. For instance Saphire is stronger than glass. What does that mean? Saphire is harder, scratches less, but is also more brittle, so break, cracks easier. So saying stronger means what's?

    Actually the anodization goes deeper on 7000 series. This was used because it is over twice has hard to bend. As it turns out it also is harder, more abrasion resistant, than 6000 series. which is good for us. But aluminum at most is only about 2.9 on Mohrs scale of hardens. Regular glass is 6. Saphire is 9. Sand particles depending on mineral are about 8.

    So the screen is way harder than the aluminum.

    No anodizing is a surface treatment

    Yes, you can tell its stronger because of the way it is.

    So far I've dropped it and it still is gold all the way through. Big improvement I'd say.

    Not many understand the hardness scale unfortunately. Just because their keys don't scratch the screen, doesn't mean a screen protector shouldn't be applied cause all it takes is a grain of sand to scratch that beautiful screen.

    I only use screen protectors to reduce the fingerprints. I never used one on half the iPhones I've owned including my 5S which currently has no scratches. I don't feel they are a necessity.

    I agree, a nice glass with oleophelic coating makes an easily replaceable safety device. Sand particles are everywhere, pick one up on your screen wipe cloth and scratch the **** out of your screen as you aggressively clean it.
