In recent years, Apple mobile phones have been the industry benchmark, leading the trend of mobile phone development.
Apple has been using an all-aluminum alloy body since the iPhone 5, because of its light weight, high temperature resistance and gorgeous metallic luster. In addition, aluminum alloy is easier to recycle, which is more in line with the contemporary environmental protection
iPhone 6 is the last generation version of the Iphone6s in 2016 and was released in September 2014. The iPhone 6 uses the 6000 series aircraft aluminum sheet , but due to the insufficient strength of the 6000 series alloy, it is easy to bend. Therefore, the iPhone 7 uses the higher-grade 7 series aluminum alloy.
The 7 series aluminum alloy is mainly made of zinc, and a small amount of magnesium and copper are added. The hardness of the aluminum alloy is closer to the hardness of the steel, which means that the iPhone 7's shell is less likely to bend, and the shell is more rigid.
The specific aluminum alloy is 7075 aluminum plate. It is a cold-treated forging alloy with high strength, far better than mild steel. 7075 is one most powerful alloys commercially available. Among this series, the 7075-T651 aluminum alloy is especially the top grade. It is known as the best product among the aluminum alloys.
It has high strength and far better than any mild steel. This alloy also has good mechanical properties and anodizing reaction. It has been used for the smart phone shell of OPPO N3 for the first time in 2014. Now more and more smart phone manufacturers choose 7075 as the phone shell.
