Titanium Grade 4
Titanium Grade 4 is the strongest of the commercially pure titanium grades, offering excellent corrosion resistance, moderate ductility, and high strength. With a higher content of oxygen compared to Grades 1–3, it is widely used in industries requiring durability in corrosive environments, such as aerospace, chemical processing, medical implants, and marine applications. Grade 4 is known for its superior strength-to-weight ratio and biocompatibility.
- High Strength: Highest strength among commercially pure titanium grades.
- Corrosion Resistance: Excellent resistance to a wide range of corrosive media, including chlorides and acids.
- Biocompatibility: Non-toxic and suitable for medical implants and devices.
- Good Weldability: Easily welded and fabricated using conventional techniques.
- Moderate Formability: Suitable for applications requiring moderate shaping and cold forming.
