| Material positioning | High-performance metal materials suitable for the manufacture of lightweight high-strength structural parts, corrosion-resistant metal parts, medical device parts, aerospace prototypes, high-end functional parts, and complex metal structural parts. |
|---|---|
| Precision performance | TC4 Titanium Alloy (Ti-6Al-4V) can achieve high dimensional accuracy through CNC machining, suitable for precision structural parts and assemblies; Metal 3D printing can achieve complex internal cavities, lattice weight reduction, and integrated structures, but the original printing precision and surface roughness are usually inferior to CNC, requiring post-processing of key holes, threads, sealing surfaces, and assembly surfaces. |
| Dimensional tolerances | Conventional dimensional tolerances for CNC machining TC4 Titanium Alloy (Ti-6Al-4V) can be referenced as ± 0.02mm to ±0.10mm, while ordinary structural parts can be evaluated at ± 0.10mm to ±0.20mm; If metal 3D printing is used, standard dimensional tolerances can refer to ± 0.10mm to ±0.30mm or higher. This value is a standard reference range and does not guarantee the absolute tolerance for all structures. Actual tolerances should be confirmed based on part dimensions, structural complexity, machining methods, and post-processing requirements. |
| Minimum Wall Thickness | For CNC machining of ordinary structures, the recommended wall thickness should not be less than 0.8mm-1.0mm. For thin-walled parts, consideration must be given to the risks of machining deformation and clamping; Metal 3D printing recommends a minimum wall thickness of no less than 0.8mm-1.2mm. Long-term load-bearing, tapping, welding, or load-bearing structures should be appropriately thickened. |
| Recommended wall thickness | For ordinary structural parts, 1.5mm-3.0mm is recommended; for load-bearing brackets, mounting seats, screw posts, and positions requiring post-processing, it is recommended to be at least 2.0mm; for lightweight metal 3D printed structures, it is recommended to combine lattice, reinforcement ribs, and force direction design to avoid local wall thickness that could cause deformation or cracking. |
| Minimum aperture | CNC machining can achieve smaller hole diameters, but deep small holes are more difficult to machine. Ordinary designs recommend hole diameters not less than 1.0mm; if metal 3D printing is used, the recommended hole diameter should be no less than 1.5mm-2.0mm. It is recommended to reserve allowance for precision holes, threaded holes, positioning holes, and assembly holes. After printing, drilling, reaming, or tapping are made. |
| Assembly clearance | For precision metal assembly, one side can be reserved at 0.02mm-0.10mm according to fitting requirements; for ordinary plug-in and assembly, it is recommended to reserve 0.10mm-0.30mm per side. If metal 3D printing of the original surface is used or post-processing such as sandblasting, anodizing, or polishing is required, the assembly allowance should be increased based on surface roughness and treatment thickness. |
| Detailed performance | TC4 Titanium Alloy (Ti-6Al-4V) suitable for machining holes, grooves, steps, chamfers, curved surfaces, threads, and structural details. CNC machining details are clear, and the edges and assembly surfaces are of good quality; Metal 3D printing can achieve complex surfaces, cavities, hollows, and lattice structures, but fine text, thin sheets, and sharp edges are affected by printing precision, support, and post-processing. Appearance identification is recommended to be achieved using laser marking, etching, or post-processing. |
| Surface effect | TC4 Titanium Alloy (Ti-6Al-4V) raw machined surface usually has a silver-gray or deep gray silver metallic texture. CNC machining can produce finer metallic textures; after sandblasting, it appears a uniform matte gray; after polishing, it produces a brighter metallic surface; anodizing can achieve decorative effects in blue, purple, gold, and other colors. The original surface of metal 3D printing is relatively rough and usually requires sandblasting, sanding, or CNC finishing to improve surface quality. |

The biggest feature of TC4 Titanium Alloy (Ti-6Al-4V) is high strength but low density, excellent specific strength, suitable for use in scenarios where both weight reduction and strength are important. Its corrosion resistance is significantly superior to ordinary carbon steel and most aluminum alloys, performing well in environments such as humidity, sweat, ocean, and weak acidic and alkaline conditions. Titanium alloy is difficult to process and has poor thermal conductivity. During cutting, it easily generates machining heat and tool wear, so processing costs are usually higher than aluminum alloys and stainless steel.
Based on wall thickness, hole position, assembly clearance, dimensional tolerances, and material usage risks, determine in advance whether the part structure is suitable for TC4 Titanium Alloy (Ti-6Al-4V).
Post-processing of TC4 Titanium Alloy (Ti-6Al-4V) affects appearance, dimensions, hole position, assembly clearance, and usage validation results, and should be explained in advance during quotation, DFM review, and sample confirmation stages.
Post-processing should focus on appearance display, dimensional fitting, connection assembly, and testing verification. Parts involving assembly positions need to be reserved in advance for machining, coating, and trial assembly allowances.
For common issues such as threads, snaps, strength, temperature resistance, and weather resistance, identify in advance whether the material needs to be replaced or if another processing method should be used.
When customer demand exceeds TC4 Titanium Alloy (Ti-6Al-4V) material boundaries, it is necessary to combine strength, temperature resistance, toughness, long-term stability, and mass production goals to promptly recommend alternative materials or processing technologies.
If lower costs and better processability are needed,6061 Aluminum Alloy or 7075 can be chosen; If stronger corrosion resistance is needed without emphasizing lightweight,316L Stainless Steel can be chosen; If higher hardness and wear resistance are required, alloy steel, tool steel, or surface-hardened steel can be chosen; If complex lightweight metal structures are needed, metal 3D printing TC4 Titanium Alloy (Ti-6Al-4V) or AlSi10Mg can be chosen; If only appearance verification is needed, photosensitive resin, nylon, or aluminum alloy sandblasted oxide parts can be chosen.
If customers care about lightweight, high strength, corrosion resistance, long-term reliability, and a premium metallic feel, TC4 Titanium Alloy (Ti-6Al-4V) is an excellent choice. If customers mainly focus on cost, fast delivery, and standard structural verification, aluminum alloy or stainless steel is usually more economical. If customers require high thermal or electrical conductivity, titanium alloy is not the first choice and should consider aluminum, copper, or other thermal and electrical materials.
