This article references authoritative sources from the “Encyclopedia of Metal Materials” to provide a detailed analysis of the performance characteristics and processing key points of TA1 (commercially pure titanium). Titanium alloys are widely used in aerospace, medical, chemical, and other fields due to their high strength, low density, and excellent corrosion resistance.
1. Basic Information of TA1
TA1, commonly known as commercially pure titanium, is a frequently used titanium alloy material with advantages such as low density, high strength, and corrosion resistance.
2. Chemical Composition
| Element | Content (%) |
|---|---|
| Titanium (Ti) | Balance |
| Aluminum (Al) | 5.5-6.75 |
| Vanadium (V) | 3.5-4.5 |
| Iron (Fe) | ≤0.40 |
| Oxygen (O) | ≤0.20 |
3. Mechanical Properties
| Property | Value |
|---|---|
| Tensile Strength | ≥895 MPa |
| Yield Strength | ≥828 MPa |
| Elongation | ≥10% |
| Hardness | ≤36 HRC |
| Density | 4.43 g/cm³ |
4. Corrosion Resistance
TA1 performs excellently in the following environments:
- Seawater: Excellent resistance to seawater corrosion
- Chloride Ions: Excellent resistance to chloride ion corrosion
- Acids and Alkalis: Good resistance to acid and alkali corrosion
- High Temperature: Can be used long-term up to 400°C
5. Typical Applications
- Aerospace (aircraft structural parts, engine components)
- Medical Devices (artificial joints, bone screws)
- Chemical Equipment (reactors, pipelines)
- Shipbuilding (propellers, seawater pipes)
- CNC Machined Parts (precision parts, sports equipment)
6. CNC Machining Performance
Characteristics of CNC machining TA1:
- High Toughness: Prone to tool sticking during machining
- Poor Thermal Conductivity: Requires adequate cooling
- Cutting Speed: 30-60 m/min
- Tool Selection: Carbide tools, coated tools
- Work Hardening: Cutting parameters require attention
7. Procurement Guide
Market Price Reference:
- Sheet: 200-300 RMB/kg
- Bar: 220-320 RMB/kg
- Tube: 250-350 RMB/kg
