As we go closer to the release of the OPPO N3, it was recently revealed that this phone’s mid-frame will not be made of magnesium-aluminium alloy but the rarely-used lithium-aluminium alloy is better than the former in terms of weight and hardness.
Lithium is the world’s lightest metal component. Adding lithium to a cellphone body made of aluminium can decrease the weight and increase its hardness. This kind of metal is usually used for airplanes and other aerial vehicles.
