While the materials Apple uses in its premium devices are always quality-focused, manufacturing processes can sometimes lead to compromises in durability. The company's return to an aluminum chassis instead of titanium for the iPhone 17 Pro and iPhone 17 Pro Max models offered advantages like better heat dissipation and lower production costs, but also drew criticism regarding scratch and impact resistance.
According to a new rumor, Apple plans to use an enhanced aluminum manufacturing process to address these issues in the iPhone 18 Pro and iPhone 18 Pro Max models.
Stronger and More Corrosion-Resistant Aluminum
According to information shared by reliable leaker yeux1122, Apple is working on a new method for refining aluminum that requires less energy. This process aims to reduce production costs while simultaneously increasing the material's durability.
The new method reportedly allows the manufacturing process to be paused and restarted, reducing material waste during production and achieving a more efficient manufacturing process. The technology also optimizes the alloy's melting point, preventing the formation of undesirable resin-like structures on the electrode surface. As a result, it can achieve higher alloy strength, improved corrosion resistance, and a smoother surface that meets Apple's quality standards.
One of the most striking aspects of the new production technique is its ability to preserve aluminum's strong heat dissipation properties. Aluminum can dissipate heat more efficiently compared to the stainless steel and titanium used in previous generations. This suggests that the A20 Pro processor, expected to be in the iPhone 18 Pro models, could offer higher and more sustainable performance under heavy loads.
It is also suggested that the same technology could be used for Apple's long-rumored foldable iPhone model. If the company successfully develops this production process, it may not need to revert to stainless steel or titanium in the future.
