Introduction

1. What is a Brake Disc?

A brake disc (Brake Disc/Disc Brake Rotor) is the core safety component of a vehicle's braking system, converting kinetic energy into thermal energy through friction with brake pads to achieve deceleration. As a leading supplier in automotive castings, we utilize high-rigidity gray cast iron (HT250/G3000) and carbon fiber-reinforced ceramic composite materials (C/SiC) to ensure exceptional thermal fade resistance and durability under extreme conditions.

2. Key Features of TIEGU Brake Discs

① Precision Machining Technology

CNC-machined for ≤0.015mm surface flatness, minimizing brake judder and noise.
Dynamic balancing eliminates vibration at high speeds, enhancing driving comfort.

② Efficient Heat Dissipation Design

Innovative venting structures (straight/curved slots, drilled patterns) improve airflow, boosting cooling efficiency by 30%+ to prevent thermal fade.
Lightweight designs (selected models) reduce unsprung mass while maintaining strength, optimizing vehicle handling.

③ Low Noise & Eco-Friendly Materials

Optimized friction surface textures reduce sharp braking noises, meeting EU ECE R90 quiet standards.
Asbestos-free brake materials ensure environmental safety and compliance with global regulations.

7. Application Scenarios (Typical Use Cases for Brake Discs)

① Passenger Vehicles (Cars, SUVs, EVs)

Urban Driving: Frequent stop-and-go traffic requires durable, low-noise, and minimal-dust brake discs.
Highway Cruising: Stable heat dissipation for sustained braking at 100-120 km/h.
Electric Vehicles: Optimized for regenerative braking compatibility and corrosion resistance (EVs lack engine heat to dry brake discs).

② Commercial Vehicles (Trucks, Buses, Trailers)

Mountain Descents: Vented/drilled brake discs prevent brake fade during prolonged downhill braking.
Heavy Loads: Thicker discs (32-40mm) with high-carbon alloy can handle 3-5x normal payloads.
Fleet Operations: Cost-effective gray cast iron brake discs with extended lifespan (100,000+ km).

③ Performance & Motorsports

Track Racing: Slotted/carbon-ceramic brake discs withstand 800°C+ temperatures during hard braking.
Drifting: Cross-drilled designs dissipate heat rapidly between cornering maneuvers.
Rally/Off-Road Racing: Coated discs resist impact from mud, water, and stones.

④ Specialized Equipment

Trains/Subways: Composite discs for high-speed friction (200-300 km/h).
Wind Turbines: Oversized brake discs for emergency rotor blade braking.
Mining Vehicles: Ultra-thick (50mm+) discs with tungsten-reinforced layers.

⑤ Regional Adaptations

Cold Climates: Anti-snow coatings prevent disc surface icing.
Coastal Regions: Corrosion-resistant treatments (galvanized) for saltwater exposure.
