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 communication devices adopt the method of using reinforcement blocks inside the mobile phone case, but the reinforcement blocks are mostly made of stainless steel or ordinary titanium alloy, which is difficult to ensure the dual requirements of rigidity and thinness
There are also some technologies that use amorphous alloys as reinforcement blocks, which greatly increases the overall cost

Description

technical field [0001] The invention belongs to the field of mobile communication and the field of alloys, in particular to a reinforcement block of a titanium alloy casing of a mobile communication device. Background technique [0002] At present, the casings of mobile communication devices, especially smartphones, are mostly made of magnesium alloy, aluminum alloy or plastic. 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 communication devices adopt the method of using reinforcement blocks inside the mobile phone case, but the reinforcement blocks are mostly made of stainless steel or ordinary titanium alloy, which is difficult to meet the dual requirements of rigidity and thinness. There are also some technologies that use amorphous alloys as reinforcement blocks, which greatly increases the overall c...
