Detailed Features
1. Chemical Specification
2. Physical Properties
The brake disc, also known as the rotor, is a critical component of a vehicle's disc brake system. It works by providing a surface for the brake pads to press against, enabling the vehicle to slow down or stop. Typically made from gray iron, a type of cast iron, it is designed to withstand high temperatures and mechanical stress. The design can vary, with some discs being solid while others feature ventilation through fins or vanes that help dissipate heat more efficiently. Ventilated discs are commonly used on front wheels where higher heat generation is expected. Our Advantages:
3. Professional Manufacturing – We use advanced environmental foundry electric stoves and production lines, with monthly output reaching up to 5000 tons.
4. Long Service Life & Quality Warranty – Our brake discs are built to last, with a warranty period of one year or 100,000 kilometers. They are also designed to operate quietly under normal conditions.
5. Strict Testing – We ensure all discs and drums meet dynamic balance standards, ensuring 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. Years of Export Experience – Familiar with various certifications and CIQ regulations, we handle all necessary documentation.
12. Short Lead Time – 20 days for a 20' container
13. Reasonable Pricing – Accept small orders (MOQ: 10–30 pcs)
14. Custom Capabilities – We can develop and produce complex designs, including size adjustments, chemical formula changes, surface treatments (DACROMET, ZINC PLATED, BLACK COLOR), and special features like drilled holes or scored lines.
15. Quality Warranty – 1 year or 100,000 km
16. Accept Drawings or Samples – We can design and develop new brake disc or rotor models based on your specifications.
We also supply brake drums.
