Apple will launch the iPhone 15 series in the second half of this year. It is worth noting that its middle frame will be made of titanium alloy. Some people will definitely be curious, why do Apple mobile phones also use titanium? TopTiTech analyzed two reasons:
1. Weight considerations.
The density of titanium alloy is generally around 4.51g/㎥, which is only 60% of steel. Some high-strength titanium alloys exceed the strength of many alloy structural steels. In this way, not only can the weight of the iPhone 15 Ultra be reduced, but also make it more durable and strong.

2. Human nature considerations.
Titanium metal is a metal that is completely non-toxic to the human body. Pure titanium is mainly composed of more than 99.9% titanium and trace amounts of iron, carbon, nitrogen, hydrogen, oxygen and other components. These ingredients are not only harmless to the human body, but also do not pollute the environment such as the land and the atmosphere. So it is very friendly to the human body and environmentally friendly.
