What Aluminum Material is used in iPhone?

Apple phones have generated such a wide range of buzz, do you know what special materials are used to make their bezels? Let’s find out together.

The regular iPhone: aircraft-grade aluminum alloys.

The regular version of the iPhone bezel uses aircraft-grade aluminum  alloys, which has several significant advantages as below:

-Good heat dissipation:

The thermal conductivity of the metal is unparalleled by other materials. The thermal conductivity of aircraft aluminum alloy is more excellent compared to stainless steel.

-Good weight reduction:

It is a lightweight and high quality material.

- Excellent texture and good grip:

Lightweight, and easy to shape, low processing costs,  can do a variety of treatments on the surface,  to make it more corrosion-resistant, wear-resistant, easy to clean, beautiful and generous. For example, anodic oxidation (coloring), electrostatic spraying, electrophoresis, brushing, sand surface treatment, etc.

In the manufacture of aircraft and spacecraft, large-size aluminum alloy materials are often used to CNC milling and machining integral aluminum alloy structural parts, replacing the traditional combined structural parts made of multiple aluminum alloy loose parts, which not only reduces the weight of structural parts significantly and improves service life, but also reduces aircraft assembly processes and manufacturing costs. This advanced design and manufacturing method relies on strict requirements on aluminum alloy materials: the maximum thickness of aluminum alloy forgings or pre-drawn plates often needs to reach 150mm or more, and the comprehensive performance of different thickness parts is highly uniform, and at the same time, it also requires excellent strength – plasticity – fracture toughness – fatigue resistance – stress corrosion resistance and spalling corrosion performance matching.

Today’s aluminum for aviation has developed to the third generation of aluminum alloy materials represented by aluminum-lithium alloy, and is used by many new aircraft types including C919. In addition, aluminum matrix composites and superplastic forming aluminum alloys are also the key research directions for aviation aluminum.
