Industrial pure titanium materials suitable for corrosion-resistant parts, lightweight metal parts, medical device parts, chemical equipment parts, marine environment parts, high-end consumer product parts, and medium-strength titanium metal structural parts.
Pure titanium TA2 is an industrial pure titanium material characterized by low density, good corrosion resistance, good biocompatibility, moderate strength, and a premium metallic texture. It is commonly used in medical devices, chemical equipment, marine environmental components, aerospace non-high-strength structural components, corrosion-resistant connectors, precision structural components, and high-end consumer product parts. Compared to TC4 Titanium Alloy (Ti-6Al-4V), TA2 has lower strength but generally better formability, weldability, and corrosion resistance; Compared to stainless steel, TA2 is lighter and has better corrosion resistance, but its processing cost is higher.
By focusing on application scenarios, boundaries of advantages, and non-recommended scenarios, it helps sales, customer service, and quoting staff quickly determine whether the material meets current part requirements.

| Material positioning | Industrial pure titanium materials suitable for corrosion-resistant parts, lightweight metal parts, medical device parts, chemical equipment parts, marine environment parts, high-end consumer product parts, and medium-strength titanium metal structural parts. |
|---|---|
| Precision performance | Pure titanium TA2 is suitable for CNC turning, milling, drilling, tapping, wire cutting, and precision machining. CNC machining can achieve better dimensional accuracy and assembly surface quality, but it is more difficult to process than aluminum alloys and ordinary steel. Actual accuracy is affected by part dimensions, wall thickness, clamping method, cutting tools, machining heat, material springback, and post-processing. Thin-walled parts, deep cavity parts, small holes, and thread positions require focused control of machining risks. |
| Dimensional tolerances | The conventional dimensional tolerances for CNC-machined pure titanium TA2 can be referenced ± 0.02mm to ±0.10mm, while ordinary structural parts can be evaluated at ± 0.10mm to ±0.20mm. Thin-walled parts, large parts, complex curved surfaces, deep holes, and post-processing parts may experience greater deviations. These values are standard reference ranges and do not guarantee absolute tolerances for all structures. It is recommended to mark tolerance requirements separately for precision assembly surfaces, threaded holes, and positioning holes. |
| Minimum Wall Thickness | The wall thickness of ordinary CNC machined structures is recommended to be no less than 0.8mm-1.0mm. Small non-stressed local structures can be further optimized according to machining capacity, but large-area over-thin areas are not recommended. Due to the high risk of heat and clamping deformation during titanium processing, thin-walled parts, long-conditioned parts, and large flat parts require special evaluation of processing deformation. |
| Recommended wall thickness | For ordinary structural parts, 1.5mm-3.0mm is recommended; for load-bearing brackets, mounting seats, screw posts, clamping positions, and positions requiring post-processing, it is recommended to be at least 2.0mm; for thin-shell parts, rigidity is improved through reinforcing ribs, rounded corners, and local thickening to avoid machining and assembly deformation. |
| Minimum aperture | CNC machining can achieve smaller hole diameters, but titanium materials are more difficult to machine with deep small holes, requiring higher chip removal and heat dissipation. Standard designs recommend hole diameters not less than 1.0mm; deep holes, small threaded holes, and high-precision positioning holes should be evaluated in conjunction with tool length, cooling, chip evacuation, and machinability assessment. For precision holes and threaded holes, it is recommended to use drilling, reaming, tapping, or post-processing to ensure dimensions. |
| 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 subsequent surface treatments such as sandblasting, polishing, anodizing, micro-arc oxidation, or other surface treatments are required, additional gaps should be reserved according to changes in surface thickness and roughness. Attention should be paid to preventing seizure between titanium threads and sliding fits. |
| Detailed performance | Pure titanium TA2 is suitable for machining holes, grooves, steps, chamfers, threads, curved surfaces, brushed textures, sandblasted appearances, and precise structural details. CNC machining details are relatively good, but too small details, deep narrow grooves, small threads, and thin edges increase machining difficulty and cost. Small text, logos, and markings are recommended to be achieved through laser marking, engraving, etching, or anodizing for color difference. |
| Surface effect | The original machined surface of pure titanium TA2 is usually silver-gray or light gray metallic, giving it a higher-grade titanium appearance. After sandblasting, a uniform matte gray effect is achieved; brushing produces a delicate linear texture; polishing produces a brighter metallic surface; and anodizing produces decorative colors such as blue, purple, and gold. Titanium has a good appearance and texture, but surface scratches and processing textures require careful control. |

Industrial pure titanium materials suitable for corrosion-resistant parts, lightweight metal parts, medical device parts, chemical equipment parts, marine environment parts, high-end consumer product parts, and medium-strength titanium metal structural parts.
The core features of pure titanium TA2 are excellent corrosion resistance, light weight, and strong overall stability, making it especially suitable for environments with humidity, seawater, weak acids and alkalis, chemical media, and biocompatibility requirements. TA2 has higher strength than ordinary plastics and most aluminum alloys in low-strength states, but is lower than TC4 Titanium Alloy (Ti-6Al-4V) and high-strength steel. It is more difficult to process than aluminum alloys and ordinary stainless steel, and during cutting it can easily generate heat, stick stick, and tool wear, resulting in higher machining costs.
Based on wall thickness, hole position, assembly clearance, dimensional tolerances, and material usage risks, determine in advance whether the part structure is suitable for TA2 Commercially Pure Titanium.
Post-processing of TA2 Commercially Pure Titanium 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 TA2 Commercially Pure Titanium 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 higher strength and better load-bearing performance are required, TC4 Titanium Alloy (Ti-6Al-4V) can be chosen; If lower cost and standard corrosion resistance are needed,304 Stainless Steel or 316L can be chosen; If lightweight and cost-effective is needed,6061 Aluminum Alloy or 7075 are options; If high thermal or electrical conductivity is required, Pure CopperT2, TU2 Oxygen-Free Copper, or aluminum alloys 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 design, corrosion resistance, biocompatibility, long-term stability, and high-end metallic texture, pure titanium TA2 is a more suitable choice. If customers are more concerned about high-strength structural performance, TC4 Titanium Alloy (Ti-6Al-4V) should be prioritized; If customers care more about cost and standard structural processing, stainless steel or aluminum alloys are usually more economical; If customers require high thermal conductivity, high electrical conductivity, or high wear resistance, TA2 is usually not the preferred material.
