What You'll Learn
The iPhone 6S uses an aluminum alloy
The iPhone 6S's shell is made of an aluminum alloy that includes approximately 5% zinc, according to a materials analysis. This composition is similar to the aluminum alloy used in the Apple Watch Sport, showcasing Apple's expertise in utilizing this material for improved structural integrity. The aluminum alloy casing provides a sturdy foundation for the iPhone 6S's internal components, ensuring that the device can withstand everyday use.
The choice of aluminum alloy for the iPhone 6S's casing offers several advantages. Firstly, aluminum is a lightweight material, making it ideal for mobile devices as it helps reduce the overall weight of the phone. Additionally, aluminum is known for its excellent thermal conductivity, which aids in heat dissipation within the device, keeping the iPhone 6S cool during operation.
Furthermore, the aluminum alloy used in the iPhone 6S is not just any standard alloy. Apple opted for aerospace-grade aluminum, which is known for its superior strength and durability. This type of aluminum undergoes an anodization process, resulting in an outer layer that is just 5 micrometers thick, providing extra protection for the device. This layer is thinner than paint yet offers enhanced resistance to scratches and corrosion, contributing to the phone's overall durability.
The use of aluminum alloy in the iPhone 6S showcases Apple's attention to detail and commitment to quality. By selecting a stronger and more durable material for the device's casing, Apple addressed the concerns raised by iPhone 6 users, ensuring that the iPhone 6S offered improved structural integrity and an enhanced user experience.

The iPhone 6S's shell is stronger and less bendable
The iPhone 6S's shell is made of aluminum alloy, which is a significant upgrade from the iPhone 6's 6000 Series aluminum. This new alloy is stronger and less bendable, addressing the "Bendgate" issue that plagued some iPhone 6 and 6 Plus users. The iPhone 6S's shell is made from the same 7000 Series aluminum alloy that Apple used for the Apple Watch Sport, taking advantage of the expertise gained from that experience.
The iPhone 6S's shell is also just 5 micrometers thick, which is thinner than paint. Despite its thinness, the aluminum alloy provides a stronger body that is more resistant to bending. This is achieved through the addition of roughly 5% zinc to the alloy, as well as small quantities of iron, which enhance durability and make the material easier to work with during the casting process.
The iPhone 6S's shell also features an anodized outside layer, a process that adds extra protection. This layer is just 5 to 10 micrometers thick and is created through a process called anodization, which increases the thickness of the natural oxide layer on the surface of the metal. The anodization process results in a harder, more corrosion-resistant surface that can better withstand wear and tear.
The use of a stronger and less bendable aluminum alloy in the iPhone 6S's shell is a clear indication of Apple's efforts to address durability concerns and improve the overall user experience. By utilizing a more robust material and adding a protective layer, Apple has created a device that feels more substantial and durable in the hand while also reducing the likelihood of bending issues that affected some of its predecessors.

The iPhone 6S uses a range of metals for electrical connections
The iPhone 6S's case is made of aerospace-grade aluminum with an anodized outer layer for added protection. This layer is just five micrometers thick, even thinner than paint. The phone also features sapphire glass, a synthetic material that is nearly as hard as a diamond, with a rating of 9 on Moh's hardness scale.
The iPhone 6S's battery uses lithium cobalt oxide (LiCoO2) chemistry in its cathode, with 60% cobalt composition. Additionally, the phone employs high-powered neodymium magnets in its speakers and headphones to produce a significant amount of sound from a compact space. These magnets are also utilized for the phone's vibration function.
Apple has also addressed the previous iPhone 6 model's "Bendgate" issue by employing a stronger aluminum alloy in the iPhone 6S, specifically the 7000 Series aluminum alloy, which is known for its enhanced strength and durability. This alloy includes approximately 5% zinc and was first used in the Apple Watch Sport, showcasing Apple's commitment to improving the durability of its devices.
