Titanium Alloy Engineering
Titanium alloy originated from aerospace engineering in the 1950s, where its exceptional strength-to-weight ratio revolutionized aircraft design. This remarkable material combines the lightness of aluminum with strength exceeding that of steel, making it the material of choice for critical applications.
Today, titanium alloy is extensively used in aerospace components, medical implants, high-performance automotive parts, and marine engineering. Its natural corrosion resistance and biocompatibility have made it indispensable across industries demanding the highest standards of performance and durability.
As a fastener material, titanium alloy delivers unmatched reliability. Its superior tensile strength ensures secure connections under extreme stress, while its resistance to fatigue and environmental degradation guarantees long-term performance. Whether in racing vehicles, aircraft assemblies, or precision machinery, titanium fasteners provide the confidence that critical joints will hold firm under the most demanding conditions.
Advantages of Titanium Material
Strength-to-Weight Ratio
Tensile strength of ≥1,100 MPa, ensuring reliable clamping force under high-speed driving conditions
Corrosion Resistant
Naturally corrosion-resistant. Remain unaffected by scratches, road salt, moisture, or aggressive cleaning agents
Lightweight
Up to 60% lighter than steel, reducing unsprung mass for sharper handling and improved ride response
High Temperature Resistant
≈400-500°C Resist strength degradation caused by braking heat and thermal expansion
Reliability & Maintenance
Engineered for long service life with minimal maintenance, even in harsh environments
Consistent Torque Retention
Lower elastic modulus and high yield strength help titanium fasteners maintain more consistent clamping force, even after multiple heat cycles and wheel removals

Knowledge About Titanium Alloys
Why We Do Not Use TC11 or TC18?
While higher-strength titanium alloys such as TC11 or TC18 exist, they are optimized for aerospace structures rather than cyclic wheel fastening.
TC4 (Ti-6Al-4V) provides a more balanced combination of strength, ductility, and fatigue resistance—critical for long-term safety in automotive applications.
Optimized for cyclic load, thermal stability, and repeat installation.
Why Titanium Does Not Rust?
Titanium does not rely on coatings for corrosion protection.
It naturally forms a stable oxide layer on its surface, which shields the material from moisture, salt, and environmental exposure—ensuring long-term corrosion resistance even after years of use.
Intrinsic material property, not surface treatment.
Is Higher Tensile Strength Always Safer?
Higher tensile strength does not automatically mean higher safety.
In wheel fasteners, excessive hardness can reduce ductility and fatigue tolerance.
A balanced material profile—rather than extreme strength—ensures stable clamping force and predictable long-term performance.
Designed for fatigue resistance, not peak tensile numbers.
