The second structural layer ratio titanium alloy substrate is used to directly select an appropriate titanium alloy substrate for use at the application end. For example, as shown in FIG. 3, when a titanium alloy substrate is to be applied to a product such as a mobile phone case, a case, or the like which is required to withstand high compressive stress and deformation resistance, the structural aspect of the titanium alloy substrate may be : the thickness is less than 3mm, the volume of the first structural layer accounts for more than 80% of all titanium alloy substrates, and the preferred ratio is that the volume of the first structural layer accounts for 20% of all titanium alloy substrates, and the volume of the second structural layer accounts for all titanium alloy substrates. 40%; or the structural form of the titanium alloy substrate may be: the thickness is between 3mm and 8mm, the volume of the first structural layer accounts for more than 40% of all titanium alloy substrates, and the preferred ratio is the first structural layer. The volume accounts for 60% of all titanium alloy substrates, and the second structural layer volume accounts for 20% of all titanium alloy substrates. The structural aspect of the titanium alloy substrate may be: thickness greater than 8 mm, the volume of the second structural layer accounts for more than 50% of all titanium alloy substrates, and the preferred ratio is that the volume of the first structural layer accounts for 10% of all titanium alloy substrates, The volume of the two structural layers accounts for 90% of all titanium alloy substrates. In addition, in the structural arrangement of the second structural layer, the second structural layer may be disposed on an outer surface layer adjacent to the first structural layer side, a partial outer layer adjacent to the first structural layer, or adjacent to the inside of the first structural layer. Side, but not limited to this.
