Extraordinary Raw Material in iPhone 6S--Tungsten

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.
