On Sep. 7 at 10 a.m. PT Apple unveiled two new versions of the iPhone. Among them, the iPhone 14 series of new mobile phones are most concerned by the outside world. The starting price of the iPhone 14 is $799, while the most expensive "Emperor" version is the 1TB iPhone 14 Pro Max priced at $1599. The most expensive iPhone. Apple phones have sparked so much buzz, do you know what special material their bezels are made of? Let's find out together.

Regular iPhone: Aerospace-grade aluminum

The regular iPhone bezel uses aerospace-grade aluminum, which has several notable advantages.

lGood heat dissipation: The thermal conductivity of metal materials is unmatched by other materials. The thermal conductivity of aviation aluminum alloy is better than that of stainless steel.

lGood weight reduction effect: it is a lightweight high-quality material.

lExcellent texture, good grip: light, easy to shape, low processing cost, and the surface can be treated with various treatments to make it more corrosion-resistant, wear-resistant, easy to care for, and beautiful. Such as anodizing (coloring), electrostatic spraying, electrophoresis, wire drawing, sand surface treatment, etc.

In the manufacture of aircraft and aerospace vehicles, large-scale aluminum alloy materials are often CNC milling to produce integral aluminum alloy structural parts, replacing the traditional composite structural parts assembled from multiple aluminum alloy parts, which not only greatly reduces the structural parts. It can increase the reliability of the service process, reduce the aircraft assembly process and reduce the manufacturing cost. This advanced design and manufacturing method puts forward very strict requirements on aluminum alloy materials: the maximum thickness of aluminum alloy forgings or pre-stretched plates often needs to reach more than 150mm, the comprehensive performance of parts with different thicknesses is highly uniform, and at the same time, it must have excellent The strength-plasticity-fracture toughness-fatigue resistance-stress corrosion resistance and exfoliation corrosion resistance match.

Today's aviation aluminum has developed to the third-generation aluminum alloy material represented by aluminum-lithium alloy, and has been adopted by many new models including C919. The representative grades are Kenlian's 2050, 2196, and Alcoa's 2099, 2397. In addition, aluminum matrix composites and superplastic forming aluminum alloys are also the current key research directions of aerospace aluminum.
