Titanium is a lightweight, corrosion-resistant metal known for its impressive strength-to-weight ratio, making it ideal for springs used in extreme environments.
Its ability to withstand high stress while maintaining a low density sets it apart from other materials, especially in applications where weight reduction and durability are critical.
At Western Spring Manufacturing, titanium is used to create custom springs that meet the demands of industries like aerospace, medical, and automotive, where reliability, longevity, and resistance to harsh conditions are paramount.

Titanium Spring Material Composition and Grades
Titanium is often alloyed with other metals to enhance its properties for specific applications. The two most commonly used titanium grades in spring manufacturing are:
- Grade 5 (Ti-6Al-4V): An alloy containing 6% aluminum and 4% vanadium, offering high strength and excellent corrosion resistance. This is one of the most widely used titanium alloys in aerospace and medical applications.
- Grade 9 (Ti-3Al-2.5V): This alloy offers slightly less strength than Grade 5 but is easier to form and machine, making it suitable for lightweight applications where flexibility is key.
Titanium alloys, particularly Grades 5 and 9, maintain their strength and corrosion resistance even in high-stress or high-temperature environments. For more details on choosing the right material for your springs, visit Choosing the Right Spring Materials for Optimal Performance and Longevity.
Titanium Properties and Characteristics
Titanium springs are prized for their unique combination of mechanical and physical properties, including:
- High Strength-to-Weight Ratio: Titanium’s strength is comparable to steel, but at about half the weight, making it ideal for applications where reducing weight is critical.
- Corrosion Resistance: Titanium is resistant to corrosion from saltwater, chemicals, and extreme weather, making it suitable for harsh environments.
- Temperature Stability: Titanium maintains its strength and performance at temperatures as high as 1,000°F (540°C).
- Non-Magnetic: This property makes titanium ideal for use in sensitive medical and aerospace applications where magnetism can interfere with performance.
Key mechanical properties of titanium alloys in spring manufacturing include:
- Tensile Strength: 138,000 psi (Grade 5) to 160,000 psi (Grade 9).
- Density: Approximately 4.43 g/cm³, which is about half the weight of steel.
- Modulus of Elasticity (E): 15,500,000 psi, lower than steel, giving titanium greater flexibility under load.
- Modulus of Rigidity (G): 6,000,000 psi.
Titanium Spring Applications
Titanium springs are particularly valued in industries where strength, weight reduction, and corrosion resistance are essential. Common applications include:
- Compression Springs:
Titanium is used in lightweight yet strong compression springs for aerospace and medical devices. - Torsion Springs:
Titanium’s flexibility and strength make it ideal for torsion springs in high-performance machinery. - Medical Springs:
Non-reactive and non-magnetic, titanium is perfect for use in medical devices and implants. - Wire Forms:
Used in custom wire forms for applications requiring strength, flexibility, and corrosion resistance.
Industries where titanium springs are frequently used include:
- Aerospace:
Ideal for components that require high strength and low weight, such as in jet engines and airframes. - Medical:
Non-magnetic and biocompatible, titanium is used in medical implants, surgical devices, and diagnostic equipment. - Automotive:
Used in performance vehicles for reducing weight while maintaining strength and durability. - Industrial:
Titanium springs are used in harsh environments where corrosion resistance and temperature stability are required.

Titanium Advantages and Limitations
Advantages:
- Exceptional strength-to-weight ratio, making titanium ideal for weight-sensitive applications.
- High corrosion resistance, especially in extreme environments such as marine, medical, and aerospace applications.
- Excellent temperature stability, maintaining performance at high temperatures.
- Biocompatibility, making it suitable for medical devices and implants.
Limitations:
- Higher cost compared to other metals like steel and aluminum.
- Lower modulus of elasticity, meaning titanium springs are more flexible and less rigid than steel.
- More challenging to machine and form due to its toughness and work-hardening properties.
Titanium Compared with Other Materials
Compared to steel, titanium offers significantly lower weight and superior corrosion resistance, making it ideal for applications in extreme environments. However, titanium is generally more expensive than steel and stainless steel. When compared to alloys like chrome vanadium or music wire, titanium excels in corrosion resistance and lightweight applications but is more challenging to work with due to its lower modulus of elasticity.
Future Trends and Innovations
Titanium is seeing increased use in industries that demand lightweight, high-performance components. Advances in titanium alloy formulations and processing techniques are making the metal more affordable and expanding its use in industries like aerospace, automotive, and medical.
In the future, improvements in 3D printing and additive manufacturing could revolutionize the way titanium springs are produced, allowing for even more complex designs and improved performance.
