Next-Generation iPhones Could Adopt 7000 Series Aluminum Used in Apple Watch Sport

Apple's next-generation iPhones could adopt 7000 Series aluminum used for the Apple Watch Sport, according to Taiwan's Economic Daily News. The so-called "iPhone 6s" and "iPhone 6s Plus" would likely use Apple's custom Series 7000 aluminum alloy, which is designed to be 60% stronger than most aluminum, and one-third the density of stainless steel, while still maintaining a light weight.

Aluminum 7000 Apple
Apple elaborated in more detail about the Series 7000 aluminum it used for the Apple Watch Sport on its website, noting that each casing is machined, polished and blasted with microscopic zirconia beads to achieve a consistent satin texture found on each Apple Watch. An additional anodized outer layer helps protect against scratches and corrosion, while the anodizing process also makes possible alternative colors like Space Gray.
For Apple Watch Sport, we started with 7000 Series aluminum — the same used in competition bicycles. We altered it to create a new alloy that’s just as light, yet even more durable — it’s 60 percent stronger than most aluminum, and one-third the density of stainless steel. It has a bright, lustrous colour and a uniform structure free of defects and impurities. Each case is machined and polished, then blasted with microscopic zirconia beads to achieve a consistent, satin texture. A special anodizing process creates a hard, clear outer layer that helps protect against scratches and corrosion.
Economic Daily News has a mixed track record at reporting on Apple's upcoming plans, and the translated report does not offer many further details, so this rumor should be treated with a proverbial grain of salt. Nevertheless, it is common for Apple to introduce new features on one device before expanding to others. Force Touch, for example, was exclusive to the Apple Watch before making its way to MacBooks, and the technology is also rumored to be included in the next iPhone.

Why not offer all 3 including the Stainless Steel and Gold option? It would be a great way to increase the profit margin. People will pay for it so why not?

I wonder if there will be Gold and SS models...


After seeing the SS watch, I'd like to see a SS iPhone. That would ooze quality.

What are the specs on the aluminum the phone is currently using? I had just assumed it was the same as the watch.


6000 Series Aluminum. Likely an alloy 6061-T6. Commonly known as "Aircraft grade" aluminum. Which I've always found funny, because the aerospace industry uses 5052-H32 alloy just as much.

Anyway, 7000 series is a step up and fairly uncommon. 5052 alloys are the most common in my experience working in sheetmetal, and 6000 alloys are used sparingly for certain circumstances. 7000 series is used in only very specific circumstances. 5000 and 6000 alloys are seen as strong/light enough for most applications.

You know the flight recorder "black boxes?" They're made from 5052-H32. And those things are designed to withstand a plane crash. So 7000 is used in only extreme cases of strength/weight optimizations.

Btw, 7000 is very hard to machine due to being so much harder than 6000. So for those of you complaining that $350 is expensive, I'm frankly STUNNED that Apple is producing a mass market product intricately machined out of a 7000 alloy and only charging $350. That is simply unbelievable, a true display of their design and manufacturing excellence.

My iPhone has, in the past, been bareback. This it the first model to be housed in a case. Why? Too damn slippery. I don't care what metal they use, just make it less slippery.

We've had stainless steel on the iPods since 2001... it SUCKS... it scratches like crazy.

IMO, the SS watch looks much better than the aluminum model. Seeing them side by side puts the SS on another level.

What ever happened to the liquidmetal hype? Did they just use that for the Apple Remote?

I remember those iPods. Scratched so easily.
Never had a SS watch before though. Might the SS Watch have the same scratching fate?.


Absolutely, it will scratch like hell. But at least you don't put your watch into your pocket, that really destroys polished stainless steel.

Aluminum is just a way better material for devices you carry around and use every day.
