Commercially Pure (CP) Titanium refers to titanium metal with purity above 99%, available in Grades 1, 2, 3, and 4 based on oxygen content and strength.
CP Titanium is known for its exceptional corrosion resistance, high strength-to-weight ratio, excellent weldability, and outstanding biocompatibility, making it suitable for marine, chemical, medical, and aerospace applications.
Typical Chemical Composition
| Element | Typical Content |
|---|---|
| Titanium (Ti) | Balance (≥99%) |
| Oxygen (O) | 0.18 – 0.40% (grade dependent) |
| Iron (Fe) | ≤0.20 – 0.50% |
| Nitrogen (N) | ≤0.03% |
| Carbon (C) | ≤0.08% |
| Hydrogen (H) | ≤0.015% |
Mechanical Properties (Typical)
| Property | Grade 1 | Grade 2 | Grade 3 | Grade 4 |
|---|---|---|---|---|
| Tensile Strength | ~240 MPa | ~345 MPa | ~450 MPa | ~550 MPa |
| Yield Strength | ~170 MPa | ~275 MPa | ~380 MPa | ~485 MPa |
| Elongation | 24–30% | 20–25% | 18–20% | 15–18% |
| Hardness (HB) | ~70 | ~90 | ~120 | ~160 |
Key Characteristics
✔ Outstanding corrosion resistance
✔ Excellent ductility and formability
✔ High strength-to-weight ratio
✔ Superior weldability
✔ Non-magnetic and biocompatible
✔ Resistant to seawater, chlorides, and acids
Strengthening & Metallurgy
CP Titanium is strengthened primarily through interstitial solid-solution strengthening from oxygen, nitrogen, and carbon.
Cold working increases strength but reduces ductility. CP Titanium does not respond significantly to heat treatment and is not precipitation-hardenable.
