Samsung exec: Galaxy S IV's plastic body balances manufacturability and 'premium feel' - Page 2

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.

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.

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 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.

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.

You mean your *coated* aluminum products. Remove a bit of coating and we can start putting money on the table.

What manner of coating would my Mac Pro, first-gen iPhone, Cinema Display, MacBook Pro, and iPad have?

Yes, me too. But not the aluminium on an iPhone or Mac.

Talk about the pot calling the kettle black!

But there's a lot of misinformation about aluminum oxidation in this thread.  Any piece of aluminum exposed to air is already oxidized, you scratch it and it will oxidize again in a few picoseconds and it's basically just a few molecules thick at the surface. You'd have to scratch for a long long time to get any significant amount of oxide, so for most intents & purposes aluminum behaves like a metal that doesn't oxidize, even if it's not anodized.  Now aluminum may corrode in a gavalnic reaction if it comes in contact with say, copper, or if it comes in contact with something that dissolves the oxide layer like methanol, but that's another story.

if that's the case, i'm sure there is website depicting all the "rusted" iphones. Since you seem to know everything, what's the link?

But... but... apparently the iPhone in my jeans pocket will corrode and leave an unfashionable stain on them!!!1! According to our new friend, Hturt Seaker.

Extra protection.

Yes, aluminum + oxygen = Thin layer of corrosion. If it is left untouched and no PH changes happen, which is the very best case scenario.

And Iphones are not tossed into bags/pockets with multiple metals and in contact with multiple solutions.

***To the surface***

Also, if the Aluminum is to be painted is not going to be anodized since they will use primer.

Interesting that neither my first gen iPhone from 2007, nor my old Powerbook G4 from 2004, both featuring aircraft grade aluminum, have any evidence of oxidation whatsoever, despite suffering horrendous abuse.

good try though.

when it's like mine and never in a case. 

Seriously, that's like asking why is tile better than linoleum if you have a mat on top of it...

The mat and the case come off.

And having a metal computer is pretty awesome too.

which of those is the iPhone?

Want to see pictures of damaged, frozen, cracked, yellowed plastic?

No photos of iPhones or Macs there. As I said, you are making shit up.

So your point about oxidisation/corrosion is completely irrelevant. Where's that unfashionable corrosion/oxidisation stain on your jeans now? Just stop making stuff up.

This guy should be banned for the nonsense he is spouting.

Hturt Seaker,

Like 99.9% of people, who try to make a point against iPhone, you have as usual gone off base with your comments/rebuttals, since many people have provided logical feedback, that firstly iPhone is premium product, secondly majority of consumers have not had any issues with oxidation (I use majority in since probably (90% or more) and thirdly Polycarbonate is 'cheap' look and there is no logical information, you can provide me that change our minds, since many critics express this view for Samsung SIII.

You were trying to make a point about the iPhone and oxidation, probably because you thought, since this phone is made of Aluminium, it has problems with oxidation, which I may add, you  have not given any factual evidence that IF this does occur AND more important is an issue for the consumer.

Now you are trying to tell us about oxidation in general sense and all many of crap, which has no relevance to this discussion and really, you have not make your point about iPhone and you cannot let go.

Please for love of God, just stay silent and learn from your mistakes.
