What is commercially pure titanium (CP Ti)?

Commercially pure titanium (CP Ti) refers to titanium with a content of over 99%, containing almost no alloying elements. Its properties mainly depend on the control of trace impurities such as oxygen and iron, which determine the strength and ductility of different grades. Grade 1 offers the highest ductility, Grade 2 provides the most balanced overall performance, while Grades 3 and 4 deliver higher strength.

Compared with titanium alloys, CP Ti has several irreplaceable advantages:

• Titanium content ≥99% forms a stable titanium dioxide passive film that self-heals, providing superior corrosion resistance in seawater, chloride, and acidic or alkaline environments.
• Virtually free of alloying elements, it does not release harmful ions, ensuring long-term safety in contact with the human body; its biocompatibility is superior to titanium alloys.
• Low impurity content and high ductility make CP Ti easier to process and weld, suitable for manufacturing complex components.
• Low density (only 4.51 g/cm³) allows for lightweight structures without compromising sufficient mechanical strength.

Thanks to these properties, CP Ti is widely used in chemical equipment, seawater desalination, aerospace structures, medical implants, and energy engineering, making it a critical material in modern high-end manufacturing.

Overview of commercially pure titanium grades

Commercially pure titanium (CP Ti) is mainly divided into four grades: Grade 1, Grade 2, Grade 3, and Grade 4. The differences among them primarily arise from varying oxygen and iron content, which directly affect the material’s strength and ductility.

Highest strength among commercially pure titanium grades, commonly used in aerospace and high-pressure equipment.

All four grades of commercially pure titanium share common properties such as light weight, non-magnetic behavior, and biocompatibility, but their application focus differs. Grade 1 is more suitable for chemical and medical uses, Grade 2 is the most common engineering material, while Grades 3 and 4 are mainly used in industries with higher strength requirements.

Standards and specifications for commercially pure titanium

These standards are the general base standards for commercially pure titanium grades 1–4, with distinctions made for the chemical composition and mechanical properties of each grade.

Grade 1 titanium

Grade 1 titanium is the softest and most ductile grade of commercially pure titanium (CP Ti). With the lowest oxygen content, it offers excellent formability and outstanding corrosion resistance, making it especially suitable for highly corrosive environments such as chemical and marine applications.

Standards:

AMS 4940, AMS-T-9046J CP4, AMS-T-9046B CP4, MIL-T-9046J CP4, Germany WS 3.7024, Germany WS 3.7025, France T35 – CP Grade 11
