Problems solved by technology

However, whether it is magnesium alloy, aluminum alloy or hard plastic, its hardness and rigidity are not very ideal, which makes it easy for users to bend and deform the mobile phone during use.
At present, some mobile phones adopt the method of using reinforcement blocks inside the mobile phone case, but the reinforcement blocks meet the demand in terms of strength, but cannot solve the problem of texture
At present, titanium alloy is also used as the mobile phone shell, but considering the cost and other factors, either the texture cannot meet the requirements, or the strength or rigidity cannot meet the requirements.

Abstract

The invention discloses a high-strength mobile phone shell. As alloy components and a preparation method of the high-strength mobile phone shell are improved, such performances as rigidity, elasticity modulus and strength of the high-strength mobile phone shell are greatly improved, and the requirements on such comprehensive performances as strength and lightness of the mobile phone shell are satisfied.

Description

technical field [0001] The invention belongs to the field of mobile communication and the field of alloys, in particular to a titanium alloy shell of a high-strength mobile phone shell. Background technique [0002] At present, mobile phone casings are mostly made of magnesium alloy, aluminum alloy or plastic. However, no matter it is magnesium alloy, aluminum alloy or hard plastic, its hardness and rigidity are not very ideal, which makes the mobile phone easy to bend and deform during use. At present, some mobile phones adopt the method of using reinforcement blocks inside the mobile phone case, but the reinforcement blocks meet the demand in terms of strength, but cannot solve the texture problem. At present, titanium alloys are also used as mobile phone casings, but considering factors such as cost, either the texture cannot meet the requirements, or the strength or stiffness cannot meet the requirements. Therefore, it is urgent to invent a mobile phone case that meets...
