    I think Apple uses aluminum because it is light weight, looks great and is recyclable. Plastic is more durable but so are plastic plates and utensils. That doesn't mean there is no reason to have fine China and silverware. iPhones fall into the latter category in terms of quality. If I planned on dropping my phone, I would probably use a ruggedized model of some sort but I don't plan on dropping it. I am very careful with it, just like I don't put the fine China in the dishwasher.





    1.- Apple uses aluminum because it looks really good. Plastic is light weight, is recyclable and can look great with professional finish.


    2.- Faulty analogy. Iphones v Galaxy do not compare to plastic house-ware v  China and silverware when it comes to price points.


    3.- Using plastic/rubber cases defeats the purpose.

    If you leave your phone out in the rain it doesn't matter if the case oxidizes. I have never personally seen an oxidized aluminum consumer electronic device that was treated properly. I have a 6 year old aluminum Mac Pro sitting on my desk and it looks like brand new. Why has it not oxidized?

    No, I am saying that the argument is invalid because it is based on personal experience. Based on my personal experience Elfs, unicorns and batman exist.

    Exactly... and the polycarbonate Samsung utilizes is some of the better advanced composite currently available, as it's light-weight, durable, highly scratch and impact resistant and can maintain its coloration throughout the entire substrate, which can never be said of devices manufactured from any type of metal alloy.

    ROTFLMAO.

    When did polycarbonate become an "advanced composite"?

    While it's true that aluminum oxidizes, it forms a very thin oxide layer which protects the bulk material from further oxidation.

    Some recycling facilities accept polycarbonate items, but most do not. Polycarbonates have no resin # and are categorized as "other", unless they have the #7 which stands for "other".

    Scratch/drop it so that the coating is gone and you will see. Just because yours has not hit the floor or been scratched it does not mean it will not. People drops phones all the time.

    A white, ferrous like, oxide mark on my cellphone is not something I would call premium feel. The rust comes off with rubbing (say in your pants) and will oxide again. Not fashionable.

    I see Android users all the time using phones with cracked screens but I'm sure a little scratch or oxidation would be completely unacceptable. Phones have a maximum life expectancy of about 5 years. Even if you left a piece of uncoated aluminum such as the old aluminum windows, out in the elements for 20 years the oxidation would be so minimal that you could polish it back to new condition with no trouble at all.

    It is. The oxide layer on aluminum is so thin it's essentially invisible.

    I call BS.

    First, you're not dealing with pure aluminum. You're dealing with an anodized layer which involves additional of chemicals.

    Second, you don't get a ferrous layer from aluminum under any conditions.

    Third, the oxides of aluminum are never classified as rust.

    Fourth the oxide layer of aluminum does not come off with rubbing (unless you're rubbing it with sandpaper.

    That is such BS. An iPhone that is in daily use is not going to oxidizes at all because it is essentially being polished all day long everyday.

    Well, when any of my aluminum products starts to actually oxidize, I'll be sure to let you know.

    I've seen aluminum get oxidized to the point that it became powder so yes it can be rubbed off.

    OMG. It's a phone. It's a tool to use for communication with others. Unless it's an iPhone, which is used for fashion statement and status quo.

    Anodized aluminum has a deliberately oxidized coat to prevent further oxidation.

    1.- Anodize is a chemical coating. Like all coatings it can be removed by scratching. In the industry we fix the oxidation with alodine, but it will do nothing to help the "premium feel."


     


    2.- I said ferrous like for a lack of better description for those unfamiliar to it. See Exfoliation Corrosion.


     


    3.- Agreed. This does not mean oxidation is not a problem though.


     


    4.- Put it in your pocket with your keys. This will also likely lead to Dissimilar Metal corrosion with a bit of rain water.

    LOL!  I actually thought about it when I wrote that, too funny.  That was a pretty cool episode.

    Someone has no understanding how oxidation works.

    I believe when that shine dulls and fades, its called an oxidation.
