For motorsport engineers and high-performance cycling brands, weight reduction is critical—but where you save weight matters most. Our Custom Grade 5 (Ti-6Al-4V) Titanium Brake Rotors offer a density of 4.43 g/cm³, approximately 42% lighter than standard 410/420 stainless steel rotors. This significant reduction in unsprung mass directly translates to faster suspension response, improved handling agility, and reduced gyroscopic effects during high-speed cornering.
Whether for a downhill MTB, a Moto3 racing bike, or a lightweight go-kart, these rotors are engineered to withstand extreme mechanical loads, boasting a tensile strength of ≥895 MPa (130 ksi) per ASTM B265 / AMS 4911 standards.
Common market concerns regarding titanium rotors—specifically warping under heat and surface galling—are addressed through our specialized manufacturing process:

*Note: For high-intensity applications (e.g., racing), we strongly recommend the Nitriding surface treatment to prevent adhesive wear (galling) and ensure compatibility with a wider range of brake pads.
Our facility is equipped with 5-axis CNC centers and specialized double-disc grinding machines. Unlike stamped rotors that require manual straightening, our rotors are machined from solid plate. This process guarantees the preservation of the material’s grain structure and ensures edge quality free from micro-cracks.
We provide advanced surface treatments tailored to your brand’s needs:
We operate under an ISO 9001:2015 certified quality management system.
(Caption: Every rotor undergoes rigorous runout testing to ensure it meets our ≤0.10mm tolerance standard.)
We specialize in helping aftermarket brands and racing teams bring their brake rotor designs to market.

To ensure optimal performance and safety of titanium brake rotors:
Q: Will titanium rotors warp under heavy braking?
A: Inferior titanium rotors made from unidirectional sheets can warp. However, our rotors are made from Cross-Rolled AMS 4911 sheets and undergo Vacuum Stress Relief, which makes them structurally stable and resistant to warping even at high operating temperatures.
Q: Do titanium rotors wear out faster than steel?
A: Raw titanium is softer than steel. However, with our optional Nitriding treatment, the surface hardness exceeds that of standard stainless steel rotors, providing excellent longevity and wear resistance.
Q: Can you manufacture floating rotors?
A: Yes, we can manufacture the titanium braking surface for floating rotors or supply full assemblies with Aluminum 7075 carriers and Titanium buttons/bobbins.
Q: What is the MOQ for custom OEM orders? A: Our MOQ is flexible to support growing brands. We start at 10 units for CNC machined custom designs.
