The recent launch of the iPhone 17 Pro has sparked considerable debate within tech circles, particularly due to a phenomenon now referred to as “scratchgate.”Early adopters and tech reviewers have quickly observed that the phone’s gleaming anodized aluminum frame is surprisingly susceptible to visible scratches. Insights from iFixit‘s disassembly of the device shed light on Apple’s construction decisions and the reasons behind the apparent fragility of its surface.
A key factor contributing to this scratching issue appears to be the switch in materials from titanium to heat-forged aluminum, which is subsequently anodized to achieve its vibrant exterior. As detailed by iFixit and materials expert David Niebuhr, the anodization process deliberately erodes the metal’s surface to form a protective oxide layer, while infusing color. However, this layer is notably brittle; it tends to remain intact on flat surfaces but is prone to flaking at sharper angles. This is particularly evident near the camera bump.
While common items like coins or keys are unlikely to scratch the anodized back of the iPhone 17 Pro, the material’s brittleness around acute edges leads to the oxide layer detaching and exposing the raw aluminum underneath.
However, the challenges surrounding the iPhone’s susceptibility to scratches are not solely attributed to the choice of aluminum over titanium. Indeed, while titanium has a stronger oxidation resistance compared to aluminum, it is the iPhone’s design that is primarily to blame.
The sharply defined corners of the camera bump lack a suitable surface for anodization, resulting in the oxide layer cracking and chipping away.iFixit suggests that if Apple had opted for a more gradual curve, the issue could have been alleviated. Increased thickness in the anodized layer could, in fact, exacerbate the problem due to the intrinsic limitations posed by the materials involved.
As highlighted by David Niebuhr, a materials scientist,
“Apple could have prevented this by making a more gradual curve and avoiding a relatively sharp corner.”
Unless users invest in a protective case, iFixit warns that the iPhone 17 Pro’s camera plateau is likely to sustain noticeable marks from regular usage.
On a positive note for repair enthusiasts, iFixit commended Apple for implementing a screwed-in battery design, facilitating safer and more straightforward replacements for users. However, many repairs still necessitate screen removal—a process that Apple has largely sidestepped in favor of a more user-friendly approach in its iPhone Air model.
