Grade 2 Titanium, also known as Titanium CP-2 (Commercially Pure Grade 2), is one of the most common grades of titanium used in various applications. Here are some key features and uses:

Ⅰ. Properties:

① Composition: Essentially pure titanium with a small amount of oxygen (up to 0.25%) and other trace elements.

② Strength: Moderate strength (lower than Grades 3 and 4 but higher than Grade 1).

③ Density: Approximately 4.51 g/cm³.

④ Corrosion Resistance: Excellent resistance to a wide range of corrosive environments.

⑤ Weldability: Excellent weldability.

⑥ Ductility: Good ductility, making it easier to form and fabricate.

Ⅱ. Applications:

① Aerospace: Used in aircraft frames, jet engines, and other aerospace components due to its high strength-to-weight ratio and resistance to corrosion.

② Chemical Processing: Utilized in chemical processing plants for tanks, pipes, and heat exchangers due to its resistance to corrosion.

③ Marine: Employed in marine applications for shipbuilding, offshore structures, and desalination plants due to its resistance to seawater corrosion.

④ Medical: Used in medical implants and devices due to its biocompatibility.

⑤ Industrial: Applied in various industrial applications where strong, lightweight, and corrosion-resistant materials are required.

Grade 2 Titanium strikes a balance between strength, formability, and corrosion resistance, making it versatile for many engineering and industrial applications.
