Description

technical field [0001] The invention relates to the technical field of electronic communication, in particular to an aluminum alloy material and a housing using the aluminum alloy material. Background technique [0002] In recent years, mobile terminal devices (such as smartphones, tablet computers, smart wearable devices, etc.) have been developing in the direction of thinning and thinning. Relatively thin and light mobile terminal devices are easily bent and deformed by external forces, resulting in damage to the entire mobile terminal device. , affecting the function. [0003] This requires that the shell of the mobile terminal device can provide sufficient structural strength support and protection, and can not be easily bent and deformed under the condition of bearing a certain degree of external force. Moreover, the mobile terminal device has higher requirements on appearance. Therefore, finding a shell that can be applied to mobile terminal equipment, so that the she...
