Commercially Pure Titanium (Grade 2)
A lower-strength but highly corrosion-resistant titanium grade. CP Ti Grade 2 is preferred for medical devices, dental applications, and chemical processing where weldability and formability matter more than ultimate strength.
About Commercially Pure Titanium (Grade 2)
Commercially Pure Titanium Grade 2 offers excellent corrosion resistance — superior to most stainless steels in chloride environments — combined with good weldability and formability. It does not contain aluminium or vanadium, making it suitable for applications where alloy sensitivity is a concern.
In AM, CP Ti Grade 2 is processed via LPBF and EBM with tensile strengths of 450–550 MPa. While significantly weaker than Ti-6Al-4V, its superior ductility (20–25% elongation) and corrosion performance make it the preferred choice for chemical process equipment, marine components, and certain medical implants where fatigue loading is moderate.
The material conforms to ASTM B348 Grade 2 and ISO 5832-2 for surgical implant applications.
Typical Applications
- Chemical processing vessels and piping
- Medical devices and surgical instruments
- Dental implants and prosthetics
- Marine hardware
- Heat exchangers
Engineering Considerations
- Lower strength than Ti-6Al-4V — not suitable for high-load structural parts
- Same inert atmosphere requirements as other titanium alloys
- Excellent candidate for applications requiring high corrosion resistance over strength
