Vratislav Holub According to a number of leaks and speculations, the expected iPhone 15 series is expected to come with quite interesting changes. If you are interested in the events surrounding the Cupertino giant, then you probably already know very well that in the case of the iPhone 15 Pro, Apple opted for titanium frames instead of the stainless steel used until now. For the first time ever, we should see an apple phone with a titanium body. The giant currently offers something like this, for example, in the case of the professional Apple Watch Ultra smart watch.
Therefore, in this article, let's focus on the pros and cons of the body of current and future iPhones. As we already mentioned, the iPhone 15 Pro will apparently offer a titanium body, while the previous "Pro" relied on stainless steel. You can read how the materials themselves differ in the article attached below.

Stainless steel
First of all, let's take a look at the current iPhone Pro, which uses the already mentioned stainless steel. This is a fairly common practice in this industry. Stainless steel brings with it a number of indisputable advantages that will definitely come in handy. It is therefore a fairly widespread material. This brings with it a very fundamental advantage - it is economically advantageous and pays off especially with regard to the price/performance ratio. In the case of steel, good hardness and durability are also typical, as well as scratch resistance.

But as they say, all that glitters is not gold. Even in this case, we would find some shortcomings in which, on the contrary, the competing titan completely dominates. Stainless steel as such is somewhat heavier, which can affect the total weight of the device. In this regard, however, it is appropriate to set the record straight. Stainless vs. the titanium bezel, while it will certainly affect the resulting weight of the device, won't make a huge difference. The second disadvantage is susceptibility to rust. Don't let the name fool you - even stainless steel can corrode. Although the material is resistant to rust, it is far from immune to it, which must be taken into account. On the other hand, something like this does not apply at all in the case of mobile phones. For the iPhone to actually experience corrosion, it would have to be exposed to extreme conditions, which is not entirely typical given the purpose of the device.
Titan
So, as we mentioned above, the iPhone 15 Pro is supposed to come with a body with a titanium frame. According to more accurate information, it is specifically supposed to be the so-called brushed titanium, which coincidentally can also be found in the case of the aforementioned Apple Watch. It is therefore a relatively pleasant material just to the touch. This, of course, brings with it a number of other advantages, due to which Apple is inclined to change. First of all, it should be mentioned that titanium is not only more pleasant, but also more luxurious, which goes hand in hand with the very philosophy of the Pro models. It will also provide other benefits to Apple phones. For example, as we mentioned above, titanium is lighter (compared to stainless steel), which can reduce the weight of the device itself. Despite this, it is more durable and is also attributed to being hypoallergenic and antimagnetic. But it is more or less clear that it is not so much about these characteristics of Apple as about the mentioned brand of luxury and durability.
But titanium is not as widespread as stainless steel, which has a relatively simple explanation. The material as such is more expensive and more difficult to process, which brings with it additional challenges. It is therefore a question of how these features will affect the iPhone 15 Pro. For the time being, however, we can expect that the current valuation of Apple phones will not change much. But what apple growers are more concerned about is susceptibility to scratches. It is generally known that titanium scratches more easily. This is exactly what people are worried about, so that their iPhone, for a considerable amount of money, does not end up as one big collector of scratches that could negate all the mentioned benefits.
What is better?
In conclusion, there is still one fundamental question. Is an iPhone with a stainless steel or titanium frame better? This could be answered in several ways. At first glance, the expected change appears to be a step in the right direction, whether in terms of design, feel to the touch or overall durability, in which titanium simply wins. And to the full. However, as we indicated above, there are concerns regarding the price of the material, possibly also in connection with its susceptibility to scratches.

I don't understand, if you have to write an article like this, why don't you ask some expert about these materials first. You obviously know about this, my dear, you'd be fine with an iPhone made of duralumin if someone gave you something cool enough to do with it, but like this it's just mindless blabbing without any meaning.
Simply put, the surface of a titanium bezel is very likely to be anodized. Titanium itself has a very solid abrasion resistance (unfortunately, it oxidizes unsightly in spots) and there is no danger of any "scratching", it is an order of magnitude more resistant than stainless steel, which is actually scratched very easily.
However, it is titanium anodizing that will give it that velvety appearance and increase its abrasion resistance. Some anodizing technologies (hard anodizing) can (although I don't really believe it myself) almost as hard as a diamond.
It's a shame that tungsten is such a difficult metal to process and manufacture. I have a tungsten watch and both the body and the sapphire crystal are unscratched after daily wear. Anyway, it would be an interesting iPhone, made of tungsten and sapphire. :)
And it would be even better from water. It never gets scratched. See, Tip?!
