Grade 2 Titanium

Grade 2 is one of the most widely used commercially pure titanium grades, offering excellent corrosion resistance, a good strength-to-weight ratio, and excellent biocompatibility. Compared with Grade 5 titanium alloy, Grade 2 has lower strength but provides excellent ductility, formability, and corrosion resistance, making it particularly suitable for chemical, marine, medical, and aerospace applications.

Appearance & Properties

Color: Silver-gray to silvery white

Density: Approx. 4.51 g/cm³

Tensile Strength: Typically ≥345 MPa

Corrosion Resistance: Excellent

Machinability: Moderate to difficult

Strength-to-Weight Ratio: Good

Ductility: Good

Biocompatibility: Excellent

Magnetism: Essentially non-magnetic

Surface Finishes: Blasting, polishing, anodizing, passivation, PVD coating, etc.

Typical Applications

Grade 2 Titanium is widely used in aerospace, medical, chemical processing, marine engineering, energy, food-processing equipment, and high-end industrial systems.

Typical parts include valve components, pump parts, flanges, pipe fittings, medical-device components, heat-exchanger parts, fasteners, and corrosion-resistant precision CNC components.

Advantages

• Excellent corrosion resistance

• Approximately 57% of the weight of steel

• Good strength-to-weight ratio

• Excellent biocompatibility

• Particularly suitable for seawater and chemically corrosive environments

Limitations

• More difficult to CNC machine than aluminum and conventional steels

• Low thermal conductivity concentrates heat near the cutting tool

• Tendency toward tool adhesion and work hardening during machining

• Higher material and machining costs than conventional steel and aluminum
