Aluminum Based Silicon Carbide (AlSiC) Brake Discs | Advanced Braking Performance
Engineered for Superior Heat Dissipation & Weight Reduction
Elevate your vehicle’s braking performance with our cutting-edge Aluminum-Based Silicon Carbide (AlSiC) Brake Discs. Combining aerospace-grade materials with precision engineering, these rotors deliver unmatched durability, thermal stability, and efficiency for luxury, sports, and high-performance electric vehicles.
- Lightweight Design for Enhanced Performance
Density: With a density of just 2.8–3.0 g/cm³, our AlSiC rotors are 50–60% lighter than conventional cast iron rotors (7.8 g/cm³).
Impact: Reduces Weight under spring by up to 40%, improving vehicle dynamics, acceleration, and fuel efficiency. Ideal for electric vehicles (EVs) and high-performance cars.
- Superior Thermal Management
Thermal Conductivity: Our rotors boast a thermal conductivity of 160–200 W/m·K, significantly higher than cast iron’s 50–55 W/m·K.
Heat Dissipation: Reduces peak operating temperatures by 15–25%, minimizing thermal fade and maintaining a stable friction coefficient (μ ≈ 0.4–0.45) even at temperatures exceeding 600°C.
- Exceptional Wear Resistance and Longevity
Hardness: The inclusion of 20–30% silicon carbide (SiC) by volume provides a Vickers hardness of 250–300 HV, compared to 180–220 HV for cast iron.
Durability: Wear rates are 40–60% lower than cast iron, extending rotor lifespan by 2–3× under extreme driving conditions.
- Optimized Thermal Expansion and Stability
CTE: Our AlSiC rotors feature a coefficient of thermal expansion (CTE) of 7–9 ppm/°C, closely matching steel hubs (≈11 ppm/°C).
Performance: Reduces thermal stress and distortion, ensuring consistent pad-to-rotor contact and braking performance.
- Corrosion Resistance for Harsh Environments
Protection: The aluminum matrix forms a natural oxide layer, while SiC resists chemical degradation.
Testing: Salt-spray tests (ASTM B117) show <5% surface corrosion after 1,000 hours, compared to >20% for cast iron.
- High Specific Stiffness and Fatigue Resistance
Stiffness: Specific stiffness reaches 35–40 GPa·cm³/g, outperforming cast iron’s 25 GPa·cm³/g.
Fatigue Strength: Fatigue resistance at 10⁷ cycles is 120–150 MPa, 2× higher than cast iron.
- Cost-Effective Alternative to Carbon-Ceramic
Cost: Our AlSiC rotors are 50–70% more affordable than carbon-ceramic systems, offering similar performance at a fraction of the price.
