Titanium alloy springs offer several advantages over ASTM A401 chrome-silicon steel springs. The diagram below compares two springs with identical specifications: a free length of 10 inches (254 mm), a spring stiffness of 275 lb/in (48.16 N/mm), and an inner diameter of 2.60 inches (66.04 mm). Both springs are designed with a similar tensile strength ratio to ensure stability under solid-state stress conditions.

1. Weight

• Steel Spring: 3.74 lbs

• Titanium Alloy Spring: 2.34 lbs (37% weight reduction)
  Titanium alloy springs are widely recognized for their lightweight properties.

2. Available Travel (Free Length to Solid Height)

• Steel Spring: 5.88 inches

• Titanium Alloy Spring: 6.34 inches (0.46 inches increase)
  Titanium alloy springs generally offer greater travel, improving space efficiency.

3. Natural Frequency

• Steel Spring: 93 Hz

• Titanium Alloy Spring: 122 Hz
  The higher natural frequency of titanium alloy enables faster response to changing loads, significantly enhancing performance in high-speed load environments.

4. Corrosion Resistance

• Steel Spring: Low corrosion resistance

• Titanium Alloy Spring: Highly corrosion-resistant

5. Magnetic Properties

• Steel Spring: Magnetic

• Titanium Alloy Spring: Highly non-magnetic
