According to early iPhone 15 reports, Apple will transform its smartphone lineup with a number of striking design modifications. And now, it appears that the introduction of a new flagship model will take place at the same time as the change to possibly ground-breaking core material.
Since the release of the 2017 iPhone X, Apple has only utilised stainless steel for its high-end smartphones. However, according to well-known leaker LeaksApplePro, the iPhone 15 Ultra, which is expected to replace the Pro Max line, would include a titanium chassis. Although titanium is far lighter and stronger than stainless steel, it is also exorbitantly costly.
The good news is that titanium has a strength-to-weight ratio that is superior to stainless steel, offering about the same strength at just 40% of the weight. This is why titanium is frequently utilised in applications that depend on weight, such as components for aeroplanes.
Additionally, titanium is 3–4 times stronger than stainless steel while weighing the same. This would offer Apple the choice to either reduce the weight of the iPhone 15 Ultra without sacrificing strength, maintain the weight while releasing the strongest smartphone ever, or—more likely—find a happy medium between the two.
Titanium seems like a no-brainer given the advantages, but the expense prevents it from being used frequently in cell phones. Stainless steel costs $1.50 to $1.50 per kilogramme, whereas titanium costs $35 to $50 per kilogramme. It’s a huge difference, therefore it comes as a real shock that Apple would introduce a titanium iPhone.
