Apple launched the iPhone 15 Pro models with titanium frames, but just two years later, this material was changed in the iPhone 17 Pro. What were the reasons behind this?

Apple launched the iPhone 15 Pro and Pro Max in 2023 with titanium material. This was considered a major step forward due to its strength, light weight, and premium feel. However, just two years later, with the launch of the iPhone 17 series, the company replaced titanium with aluminum. The iPhone 17 Pro and Pro Max were launched with aluminum frames. So, what happened in just two years that forced Apple to change its decision? Let's find out the answer to this question. 

Why did Apple choose titanium?

Apple chose titanium to differentiate its Pro models. It's a lighter and stronger alternative to stainless steel, allowing Apple to reduce the iPhone 15 Pro's weight by 19 grams. Titanium is also less prone to scratches and dents. It's also used in aerospace and luxury watches, which was one reason for its selection.

What's wrong with titanium?

Along with its many benefits, titanium also comes with several drawbacks. Its poor thermal conductivity has led to iPhones overheating during gaming, fast charging, and other heavy tasks. This problem was exacerbated by powerful chips like the A17 Pro. Furthermore, titanium also posed production challenges. It required specialized tools and slowed production speeds, increasing the company's manufacturing costs. 

How is aluminum a better choice than titanium?

Aluminum is easier to manage heat than titanium. This improves the iPhone's thermal performance, allowing Apple to include a larger battery. It's also easier to produce and lowers costs. Aluminum has a lower carbon footprint than titanium, which will help Apple meet its environmental goals. For these reasons, Apple chose aluminum over titanium.
