What is TA2 Pure Titanium?
TA2 is a grade of commercially pure (CP) titanium, also known as Grade 2 Titanium in the ASTM system. It is the most widely used pure titanium grade in industrial applications due to its excellent balance of strength, formability, and corrosion resistance.
TA2 titanium is commonly used in chemical processing, marine applications, aerospace components, and medical devices where corrosion resistance is critical.
Chemical Composition
| Element | Content (%) | Standard |
|---|---|---|
| C | 0.95-1.05 | ASTM/GB |
| Cr | 4.75-5.50 | ASTM/GB |
| Mo | 0.90-1.40 | ASTM/GB |
| V | 0.15-0.50 | ASTM/GB |
| Fe | Balance | ASTM/GB |
Mechanical Properties
| Property | Value |
|---|---|
| Tensile Strength | ≥ 345 MPa (50 ksi) |
| Yield Strength | ≥ 275 MPa (40 ksi) |
| Elongation | ≥ 20% |
| Hardness | ≤ 200 HV |
| Density | 4.51 g/cm³ |
Key Features
- Excellent Corrosion Resistance: Outstanding resistance to seawater, chlorides, and most acids
- Good Formability: Easy to weld, form, and fabricate
- Lightweight: 45% lighter than steel with comparable strength
- Biocompatible: Safe for medical and food processing applications
- Cryogenic Performance: Maintains properties at very low temperatures
Common Applications
- Chemical Processing: Heat exchangers, reactors, piping systems
- Marine Industry: Propeller shafts, submarine hulls, desalination equipment
- Aerospace: Hydraulic systems, engine components, fasteners
- Medical Devices: Surgical instruments, implants, medical equipment
- Power Generation: Condenser tubes, cooling systems
- CNC Machined Parts: Custom components for various industries
Machinability & CNC Processing
TA2 pure titanium has moderate machinability. While softer than titanium alloys like TC4, it still requires proper machining techniques:
- Cutting Speed: 30-60 m/min (lower than aluminum or steel)
- Feed Rate: 0.1-0.3 mm/rev
- Tool Material: Carbide tools with TiAlN coating recommended
- Coolant: Use generous coolant to prevent work hardening
- Chip Control: Continuous chips require proper chip breaking
Tip: Avoid dwelling the tool to prevent work hardening. Maintain consistent feed rates.
TA2 vs TC4 Titanium
| Property | TA2 (Grade 2) | TC4 (Grade 5) |
|---|---|---|
| Tensile Strength | 345 MPa | 895 MPa |
| Yield Strength | 275 MPa | 828 MPa |
| Hardness | ≤ 200 HV | ≤ 350 HV |
| Formability | Excellent | Good |
| Corrosion Resistance | Excellent | Very Good |
| Cost | Lower | Higher |
When to Choose TA2: When corrosion resistance and formability are more important than ultimate strength.
When to Choose TC4: When high strength-to-weight ratio is critical (aerospace, racing).
