When Apple unveiled the iPhone 7 in 2016, it hailed the device as a behemoth of innovation, touting its water-resistant design, impressive cameras, and snappy performance. But amidst the fanfare, one question lingered: Is the iPhone 7 scratch-resistant? In this article, we’ll delve into the realm of materials science, examine real-world tests, and explore user experiences to separate fact from fiction.
The Materials Behind The Magic
The iPhone 7’s exterior is crafted from a blend of materials, including aluminum, glass, and stainless steel. The bulk of the device’s body is made from a high-strength, aerospace-grade 7000-series aluminum alloy. This material is prized for its exceptional strength-to-weight ratio, corrosion resistance, and – you guessed it – scratch resistance.
The display, on the other hand, is protected by a layer of Ion-X glass, a proprietary material developed by Corning, the same company behind Gorilla Glass. Ion-X glass is designed to be thinner, lighter, and more resistant to scratches and cracks than its Gorilla Glass counterparts.
The Science Of Scratch Resistance
To understand why some materials are more scratch-resistant than others, we need to explore the science behind scratching. When an object comes into contact with a surface, it applies pressure, causing the surface to deform. The amount of pressure required to cause deformation depends on the surface’s hardness, which is measured in units of pascals (Pa).
The iPhone 7’s aluminum alloy has a hardness of around 160-170 HV (Vickers hardness), which is relatively high compared to other metals. Ion-X glass, on the other hand, boasts an impressive hardness of around 600-700 HV, making it one of the most scratch-resistant materials available.

Numerous tests have been conducted to put the iPhone 7’s scratch resistance to the test. In a widely publicized test by CNET, the iPhone 7 was subjected to a series of scratch tests using increasingly abrasive materials, including steel wool, keys, and even a knife.
The results? The iPhone 7’s aluminum body showed minimal scratches even when subjected to the harshest materials, whereas the Ion-X glass display remained virtually unscathed. Similar tests conducted by other outlets, including Wired and TechRadar, yielded similar results.
User Experiences: The Good, The Bad, And The Ugly
While controlled tests provide a valuable insight into the iPhone 7’s scratch resistance, real-world user experiences offer a more comprehensive understanding of the device’s durability.
The Good: Many iPhone 7 owners have reported minimal scratches and scuffs, even after months of heavy use. Some have even confessed to accidentally dropping their devices without sustaining significant damage.
The Bad: However, some users have reported more severe scratches and damage, often resulting from accidental drops or exposure to harsh environments. In some cases, the aluminum body has been known to develop unsightly scratches and discoloration.
