Since Apple launched the first iPhone in 2007, the iconic smartphone has sold over 700 million units around the world. This best-selling handset sets the standard for smartphone performance and features. However, the iPhone 6S would not be possible without the extraordinary raw materials that line the insides of the case. So what is in the Apple iPhone 6S?

About the iPhone 6S’s screen, it’s much more complex than it may seem. The potassium ions make aluminosilicate glass strength. A layer of indium tin oxide makes it touchscreen capable and small amounts of rare earths enables certain colors on the display.

Lithium cobalt oxide (LiCoO₂) with 60% of cobalt is in the iPhone 6S’s battery, also a graphite anode and aluminum casing are being used.

About the electronics, the phone’s processor is mainly made from silicon, metals like cooper, gold, silver and tungsten are used for electrical connections within a iPhone 6S. Besides, the introduction of tantalum makes the electricity flow managed to guarantee.

Tungsten-copper and tungsten-silver carbide both have the properties as same as copper and silver--the good electrical, thermal conductivity. Thus, making them become very effective contact materials in working parts, such as manufacturing knife switch, circuit breakers, spot welding electrodes.

Things someone really cases is the camera, what is the extraordinary raw material used in Apple 6S’s camera? Sapphire glass, which makes it nearly as hard as a diamond, because of the Moh’s hardness reaches to 9.

It is reported that Apple Inc. will open a conference at March 21^st, something new relating with Apple Watch2 will be shared in addition to publishing iPhone SE and the new iPad which are concerned, such as a new generation of upgraded model.



In the designing, Apple Watch 2 won’t be made drastic changes, but to improve the portability of the device through introducing new materials and magnetic strap to attract new buyers. Apple reported to try new materials include tungsten, palladium, titanium and platinum.

In the function, a new health function will be introduced into the second generation model (or a new software upgrade) - when the user is detected unforeseen circumstances, the device will automatically call for help to a doctor.

About the configuration, as the upgraded model, upgrading the hardware configuration is natural essential. It is reported that Apple Watch 2 will have upgrade in the following areas:
1. Introducing A32 processor (ARM Cortex-A32 CPU), A32 is the smallest, lowest power consumption of ARM v8-A designing;
2. Networking, the second generation model may bring 3G/4G networking feature, making it handling data traffic by their own short-term;
3. Battery life, in order to solve the problem that weaker endurance of Apple Watch, Apple Inc is reported to combine with Samsung and LG to develop thinner OLED panels for fitting the larger capacity battery.
4. The camera, a Face-Time camera will be added in the body, making video calls directly on the wrist becoming possible.

Tungsten, as a typical rare metal, an important strategic resource of the state, has the very important application. Tungsten is an important part of contemporary high-tech new material, and it is widely used in fields such as electro-optical materials, special alloys, new features materials and organometallic compounds, because of its properties such as high melting point, hardness and density, good electrical conductivity and thermal conductivity, low coefficient of expansion.
