What's up, guys? Louie here back with another video and things are about to get scientific here on Unbox Therapy.

You might recall a previous video in which I showed you this

what is likely the backplate for the upcoming iPhone 6s

I just compared the dimensions in that video

I looked at this shell compared to the shell from the standard iPhone 6 I have over here.

But, the speculation was actually relating to the material in use and what the effect of that might have on the durability of the upcoming device.

Now, a lot of speculation is out there regarding this new phone and whether or not it will move to something called a 7000 series aluminum.

Most people out there probably don't know exactly what that means,

That's why I did some extensive research, and even some fairly elaborate testing.

Now before I get into that, you probably noticed this thing over here.

This is obviously some kind of monstrosity fabricated from the geniuses over at D-brand.

This is Skins. If you don't know who they are, you should go check them out.

What this is, a makeshift bang test machine.

which will essentially give us a readout of how much weight is necessary, or how much force, in a weight equivalent,

is necessary to actually bend these two shells.

Potentially, it'll be an even more interesting test because

we can actually look at the aluminum attributes and how that affects the durability of a device and why Apple might be moving to a different material.

So eventually I realized that what I needed was something called an XRF analyzer.

This thing shoots X-rays into common alloys and tells you what their elemental makeup is.

Now before we get into the elemental makeup of each of these iPhone shells,

I want to give a shout out to Elemental Controls in Mississauga

I hit these guys up shortly after I found out about these XRF analyzers

They were like come on down, let's do the tests,

So here's the readout for the iPhone 6 shell.

Essentially what we ended up with is a common alloy

As you can see up here, the readout was 6063 from the 6000 series of aluminum.

This 6000 series alloy is probably the most commonly bought, sold, manufactured alloy on the planet.

Some speculate it represents somewhere in the neighborhood of 75 to 80 percent of all alloys in use.

It's fairly easily machineable so obviously it makes sense to use it in manufacturing

It also anodizes very easily and as you know

with iPhones and various other electronics that use aluminum, generally there's some kind of anodization that gives it its color.

you can see the exact elemental make up of 6063.

It's mostly aluminum, 98.94 percent, with a tiny bit of iron, a little bit of silicon, and a little bit of magnesium.

Actually this is mostly the abundant element, aluminum.

Eventually 6063 aluminum is used in so many applications that you're probably familiar with.

The only possible problem with this material is that it bends a little bit.

as you know, you've witnessed in previous videos

Okay, so there's the reading on the iPhone 6,

the old shell, which we know, has been prone to bending

well let's go ahead and look at the report for the new one.

Now this is where things gets interesting.

The alloy has a much thicker anodization.

Before taking our reading, we actually had to sand off that anodization to get a clear reading of the aluminum itself.

Sanding this anodization off proved to be far more difficult, implying that it's a much thicker coating

it's going to stand out, and what's important about this is

it's not the aluminum that's at 91.174 percent of the makeup, but the zinc.

Now we took a number of different readings on this component

and each one came out a little bit different

but essentially we always had the significant presence of zinc, which points to 7000 series aluminum.

The addition of zinc here improves the strength of the material

Was this bendgate thing really as small of an impact as people were speculating?

Or maybe it affected more devices than we even know.

They've selected 7000 series now and reinforced it in specific regions

and ultimately, the expectation would be that we're going to see less bends in the next version than we saw in the previous

With the addition of zinc, we are also going to increase the likelihood of corrosion.

And that is what leads me to believe that they've gone with a different anodization process

They've increased the amount that's on the surface.

Now the next drawback of 7000 series aluminum: expense

This stuff is way more expensive for a number of reasons.

but it mostly has to do with the availability.

This is about to become a lot more common

but in the meantime, the likely effect is that the cost of production for an iPhone could go up.

This new material could cost as much as 5 times more

that this is going to be a little more labor intensive

to get it out in volume when compared to the 6000 series construction.

So, beside me. I mentioned earlier, I have this crazy contraption which is going to measure the force applied to each of these units

and I'm going to go ahead and find out exactly how much stronger this component is

as it is the backbone for the upcoming iPhone.

Let's go ahead and start with the iPhone 6 shell in order to get our baseline

The reason you're already seeing a reading on the scale here is because

this top portion of our contraption is on top of the scale itself.

If I lift this up, you'll see it comes down to zero. Zero pounds, zero ounces

So when considering the total amount of force that's applied to the actual units,

we essentially need to start with the weight of this component itself.

So, the moment that I insert this shell, we're starting at a point of two pounds and in this case, ten ounces.

Now let's go ahead and slowly apply some pressure to this
