Grade 9 Titanium

Grade 9 (Ti-3Al-2.5V) is a medium-strength alpha-beta titanium alloy containing approximately 3% aluminum and 2.5% vanadium. It provides higher strength than commercially pure Grade 2 titanium while offering better formability than Grade 5, providing a good balance of lightweight performance, corrosion resistance, and mechanical strength.

Appearance & Properties

Color: Silver-gray to silvery white

Density: Approx. 4.48 g/cm³

Tensile Strength: Typically around 620 MPa or higher, depending on product form and condition

Corrosion Resistance: Excellent

Machinability: Moderate to difficult

Strength-to-Weight Ratio: Excellent

Formability: Good

Fatigue Resistance: Good

Magnetism: Essentially non-magnetic

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

Typical Applications

Grade 9 Titanium is widely used in aerospace, drones, automotive and motorsports, bicycles, medical equipment, sporting goods, and high-performance industrial equipment.

Typical parts include aerospace hydraulic tubing components, drone structures, lightweight brackets, tube fittings, bicycle components, fasteners, shafts, and precision CNC parts.

Advantages

• Good strength-to-weight ratio

• Higher strength than Grade 2 titanium

• Better formability than Grade 5

• Excellent corrosion resistance

• Suitable for lightweight, medium-to-high-strength components

Limitations

• Lower strength than Grade 5

• More difficult to CNC machine than aluminum and conventional steels

• Low thermal conductivity requires careful control of cutting heat

• Relatively high material and machining costs
