Scope

Main Technical Content: **Technical Requirements:** 1. **Materials** 1.1 The casting ingots used for production and processing shall be melted in a vacuum self-consuming arc furnace, with no fewer than two melting cycles. The last melting cycle shall not allow the addition of any elements. 1.2 Tungsten electrode arc welding is prohibited for self-consuming electrodes. 1.3 Any recycled titanium and titanium alloys are strictly prohibited from being used as raw materials for casting ingots and processing materials. 1.4 The recommended heat treatment process is: - Temperature: 650°C to 760°C - Duration: 0.5 to 3 hours - Air cooling. Vacuum annealing may also be used. The supplier may adjust the heat treatment process as needed. 2. **Chemical Composition** 2.1 The chemical composition of the antibacterial titanium alloy Ti6Al4V5Cu-ELI shall comply with the requirements specified in Table 1. Other elements specified in Table 1 shall comply with the provisions of GB/T 3620.1. Table 1: Chemical Composition of the Antibacterial Titanium Alloy Ti6Al4V5Cu-ELI 2.2 The allowable deviations in chemical composition during the buyer’s reinspection shall comply with the provisions of GB/T 3620.2. 3. **Product Classification** 3.1 **Plates** 3.1.1 **States and Specifications** - The state and specifications of plates shall comply with Table 2. Table 2: States and Specifications of Plates 3.1.2 **Dimensional Tolerances** - The allowable deviations in thickness, width, and length of plates shall comply with Table 3. Table 3: Allowable Deviations in Thickness, Width, and Length of Plates 3.1.3 **Tensile Properties** - The room-temperature tensile properties of plates shall comply with Table 4. Table 4: Room-temperature Tensile Properties of Plates 3.1.4 **Bending Properties** - Plates with a thickness of no more than 5.0 mm shall undergo bending tests. The bending diameter and angle shall comply with Table 5. No
