Detailed Features
1. Chemical Specification
2. Physical Properties
The brake disc, also known as the rotor, is a key component in a wheel's disc brake system. It is the surface against which the brake pads press to create friction and slow down or stop the vehicle. Typically made from gray iron, a type of cast iron, it offers durability and heat resistance. The design of the disc can vary—some are solid, while others feature ventilation with fins or vanes that help dissipate heat. This is especially important for heavier vehicles or those with higher performance requirements, where heat management is critical.
Our Advantages:
3. Professional Manufacturing – We use high-volume, environmentally friendly foundry electric furnaces and advanced production lines, with a monthly output of up to 5,000 tons.
4. Long Service Life & Quality Warranty – Our brake discs are designed for long-term use and come with a warranty of 1 year or 100,000 km. They also operate quietly under normal conditions.
5. Strict Testing – We ensure all discs and drums meet dynamic balance standards to guarantee stability during driving.
6. Material: Cast Iron
7. Standard: HT-250 raw material, G3000 standard
8. Style: Solid or Vented
9. Packing: Neutral or Color Carton, Poly Wood Pallet
10. Certifications: TS16949, ISO 9002, and Short-term Export Credit Insurance
11. Experienced Exporter – We have extensive experience in exporting and are familiar with various certifications and customs regulations. We can handle all necessary documentation.
12. Short Lead Time – 20 days for a 20' container.
13. Competitive Pricing – Acceptable for small orders, with MOQ as low as 10–30 pcs.
14. Custom Production – We can develop and produce complex parts, including custom sizes, modified chemical formulas, surface treatments (DACROMET, ZINC PLATED, BLACK COLOR), and special drilling or scoring patterns.
15. Quality Warranty Period – 1 year or 100,000 km.
16. Accept Drawings or Samples – We can design and explore new brake disc or rotor models based on customer drawings or samples.
Also available: Brake Drums.
