Grade 5 Titanium

Grade 5 (Ti-6Al-4V) is one of the most widely used titanium alloys, consisting primarily of titanium with approximately 6% aluminum and 4% vanadium. It offers an excellent strength-to-weight ratio, corrosion resistance, and fatigue performance. Compared with commercially pure Grade 2 titanium, Grade 5 provides significantly higher strength, making it ideal for aerospace, automotive, medical, and high-performance mechanical components.

Appearance & Properties

Color: Silver-gray to silvery white

Density: Approx. 4.43 g/cm³

Tensile Strength: Typically around 895 MPa or higher for common annealed specifications

Corrosion Resistance: Excellent

Machinability: Difficult

Strength-to-Weight Ratio: Excellent

Fatigue Resistance: Good

Heat Resistance: Good

Magnetism: Essentially non-magnetic

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

Typical Applications

Grade 5 Titanium is widely used in aerospace, drones, automotive and motorsports, medical equipment, robotics, energy, and high-performance industrial systems.

Typical parts include aerospace structures, engine components, drone structures, high-strength fasteners, robotic joint components, medical devices, brackets, shafts, and lightweight precision CNC parts.

Advantages

• Excellent strength-to-weight ratio

• Significantly stronger than Grade 2 titanium

• Excellent corrosion resistance

• Good fatigue and elevated-temperature performance

• Ideal for high-strength lightweight components

Limitations

• Difficult to CNC machine

• Low thermal conductivity concentrates cutting heat near the tool

• Tendency toward tool adhesion and accelerated tool wear

• Higher material and machining costs than aluminum and conventional steels
