Apple may use a specially treated titanium case in future products

According to a newly granted patent application, Apple is studying the use of uniquely processed titanium for future MacBooks, iPads and iPhones.

The patent explains that the anodized aluminum currently used in MacBook and iPad is not as hard or durable as titanium. However, the hardness of titanium makes it "difficult to be etched", which means it may be "aesthetically unattractive." This patent attempts to solve this problem by outlining blasting, etching, and chemical treatment to make the titanium casing look more attractive.

The patent also points out that this textured titanium case is suitable for MacBook, iPad, iPhone and Apple Watch. Apple has used titanium casings in a few products, such as the PowerBook G4 that went on sale from 2001 to 2003. However, Apple's first entry into the titanium case was hindered by some problems, such as fragility leading to cracking, and the paint peeling off easily.

Currently, the only Apple product that uses a titanium case is the Apple Watch Edition, which seems to be closer to the unique surface treatment described in the patent than the Titanium PowerBook G4.
