this is big this is big guys what's up guys Lew here back with another video and things are about to get scientific right here on unbox therapy you might recall a previous video in which I showed you this what is likely the back plate for the upcoming iPhone 6s now I just compared the dimensions in that video I looked at this shell compared to the shell from the standard iPhone 6 that 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 I certainly didn't that's why I did some extensive research and even some fairly elaborate testing but 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 skins if you don't know who they are you should definitely go and check them out but this is a makeshift Ben test machine which will essentially give us a readout how much weight is necessary or how much force in a weight equivalent is necessary to actually bend these two shells now these aren't the complete phones keep that in mind potentially 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 the six and the new 6s 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 and they were like come on down let's do the tests so here's the readout for the iPhone 6 show essentially what we ended up with is a common alloy as you can see up here the readout was six zero six three from the 6000 series of aluminum now this 6000 series alloy is probably the most commonly bought sold manufactured alloy on the planet some speculated represents somewhere in the neighborhood of 75 to 80% of all alloys in use it's fairly easily machinable so obviously it makes sense to use it in manufacturing it also anodized this very easily and as you know with iPhones and various other electronics that use aluminum generally there's some kind of anodized ation that gives it its color looking closer at the readout you can see the exact elemental makeup of 6:06 3 it's mostly aluminum 98.9 4% with a tiny bit of iron a little bit of silicon and a little bit of magnesium essentially this is mostly the abundant element aluminum so this 6 0 6 3 aluminum is used in so many applications that you're probably familiar with windows doors automotive the only possible problem with this material is that it bends a little bit as you know you've witnessed in previous videos it's not the strongest type of aluminum okay so there's the reading on the iPhone 6 the old shell which we know has been prone to bending but let's go ahead and look at the report for the new one now this this is where things get interesting first things first 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 we did the same for the older shell but sanding this anodization off proved to be far more difficult implying that it's a much thicker coating now under the x-ray under the gun what's going to stand out and what's important on this list is not the aluminum that's at ninety one point one seven four 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 this significant presence of zinc which points to 7000 series aluminum the addition of zinc here improves the strength of the material okay so why did Apple change was this bendgate thing really as small of an imp as people were speculating or maybe it affected more devices than we even know bottom line is this they've selected 7000-series now they've 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 but it does come at a cost with the addition of zinc we are also going to increase the likelihood of corrosion nobody likes 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 aluminium expense this stuff is way more expensive for a number of reasons but it mostly has to do with the availability and 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 in this new material could cost as much as five times more I think it's fairly safe to say that this is going to be a little bit more labor-intensive to get out in volume when compared to the 6000 series construction but the real question here is how much stronger is it all worth it so beside me as mentioned earlier I have this crazy contraption which is going to measure force apply 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 so let's go ahead and start with the iPhone 6 shell in order to get our baseline now 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 0 0 pounds 0 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 2 pounds and in this case 10 ounces 10 point 2 or 3 ounces so this is the old shell we've now added the additional weight the actual shell now let's go ahead and slowly apply some pressure to this keep an eye on that scale we're now approaching closer to 20 pounds 1924 just under 30 pounds of force and we are completely bent there you can see here at the volume buttons in that weak spot at about 30 pounds we are bent I'm going to go ahead and remove this really quickly both sides on the two obvious weak points as we've known previously near the power button as well as near the volume rocker we have weakness and we have a best a representation of not just the bend ability of the material but also those weak points that I mentioned in the previous video but what happens if we increase the pressure even more okay so we're bright back at 30 pounds there you can see it's starting to bend by 32 it's really having difficulty and by I don't know let's say by 35 I mean it's indistinguishable essentially you have significant bending at 30 pounds of force and anything beyond that the the shell just begins to crumble significantly it's interesting in this particular case we have a bend right across those two weak points there now it's time for the 6s back plate the thing we've identified as probably from this 7000 series of super strong aluminum used in aerospace and now potentially used in your phone so let's go ahead and do the same thing so there we go of course the measurement hasn't changed much here because the shell doesn't weigh very much itself we're going to go ahead and start to tighten it down now the magic number here as you know is thirty thirty pounds we want to see what happens at about 30 pounds of force clothes we are at 31 pounds over 31 pounds and it's not significantly bent yet keep going here 36 weight Wow we are at 46 pounds now 53 this is getting tough to twist now 60 pounds of force 70 the old phone the entire phone bent at 70 pounds of force on the previous version 80 I can hear it bending now 80 pounds Wow 80 pounds was the number guys I'm gonna go ahead and remove this now 30 and 80 that is a huge improvement Wow did not expect it to be that much stronger of course they're both bent now and they still bent relatively in the same locations but you will notice here though the power button the power cut out on this one untouched compared to the old device right around the interior of the volume buttons where there was that weak point not exactly where it bent bent below there but not with as much aggressiveness as on the old one and we were applying more than double the amount of force this is pretty damn impressive guys honestly beyond what I expected to find not only do we have evidence here that this is made out of 7000 series aluminum but now we understand the impact of that the impact of that is a phone that will be more than twice as strong as the previous version is this a win for consumer reporting when the bendgate video came out I didn't really understand the magnitude of it but what this looks like is that everybody who picks up the next version of the iPhone is going to get something that's extremely strong and that video might have something to do with it so there you have it hopefully you guys enjoyed this content if you did make sure to leave a thumbs up down below or you could do one better and share this video with anyone you think would find it interesting shout out to the two companies who helped out with this there's actually three total people who helped make this video possible so you've got Sonny Dixon who hooked me up with the shell for the upcoming iPhone the iPhone 6s shell you've got D brand who built this crazy contraption I'll link them down below so you can check out their skins for all kinds of different devices and then of course elemental controls who came out of nowhere to bring the heat with the scientific data amazing stuff this is really a next-level type video I hope you guys appreciated it we had a lot of fun making it so there you have it I guess you're a little bit smarter I know I am thanks again for watching and I'll catch you on the next episode subscribe for more videos like this later guys
