Detailed Features
1. Chemical Specification

2. Physical Properties
The brake disc (or rotor) is the rotating component of a wheel’s disc brake system, where the brake pads press against to create friction and slow down the vehicle. It is typically made from gray iron, a type of cast iron known for its durability and heat resistance.
Disc designs can vary—some are solid, while others are ventilated with fins or vanes that help dissipate heat more efficiently. Ventilated discs are commonly used in front wheels, especially on heavier vehicles, as they provide better cooling and reduce the risk of overheating during prolonged braking.
Our Advantages:
3. Professional Manufacturing: We use high-volume environmental foundry electric furnaces and advanced production lines, producing up to 5,000 tons per month.
Professional Manufacturing
4. Long Service Life and Quality Warranty: Our brake discs are designed for low noise, long life, and reliable performance.
5. Strict Testing: We ensure dynamic balance for both discs and drums, guaranteeing stable performance during driving.
6. Material: Cast Iron. 7. Standard: HT-250 raw material, G3000 standards.
8. Style: Solid or Vented Brake Discs. 9. Packing: Neutral or Color Carton, Poly Wood Pallet.
10. Certifications: TS16949, ISO 9002, and Short-term Export Credit Insurance.
11. Years of Export Experience: Familiar with various certifications and government regulations, including CIQ and customs documentation.
12. Short Lead Time: 20 days for a 20' container.
13. Reasonable Pricing: Accept small orders with MOQ of 10–30 pcs.
14. Custom Production: Capable of manufacturing complex parts, including size adjustments, chemical formula modifications, surface treatments (DACROMET, ZINC PLATED, BLACK COLOR), and drilled holes or etched patterns.
15. Quality Warranty: 1 year or 100,000 km.
16. Accept Drawings or Samples: Can develop new products based on customer designs.
