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 is the part that rotates with the wheel and is pressed against by the brake pads to create friction and slow down or stop the vehicle. Typically made from gray iron, it can be either solid or ventilated, depending on the vehicle's performance requirements. Ventilated discs are commonly used in high-performance or heavy-duty applications as they help dissipate heat more effectively, ensuring better braking efficiency and longevity. Our Advantages:
- **Professional Manufacturing**: We have advanced foundry equipment and a production line capable of producing up to 5,000 tons per month, ensuring high-quality and consistent output.
- **Long Service Life & Quality Warranty**: Our brake discs are designed for durability, with a warranty of 1 year or 100,000 kilometers. They also operate quietly and reliably.
- **Strict Testing & Dynamic Balancing**: Every product undergoes rigorous testing to ensure stability and balance during operation, providing a smooth driving experience.
- **Material & Standards**: Made from cast iron, meeting HT-250 raw material standards and G3000 specifications. Available in both solid and vented styles.
- **Packaging Options**: Neutral or branded cartons, with poly wood pallets for secure shipping.
- **Certifications**: We hold TS16949 and ISO 9002 certifications, along with short-term export credit insurance for added security.
