1. Chemical Specification
2. Physical Properties
The brake disc (or rotor) is the rotating part of a wheel’s disc brake assembly, against which the brake pads are applied. Typically made from gray iron, it is an essential component in modern braking systems. The design can vary—some discs are solid, while others feature internal vanes or fins to improve heat dissipation. Ventilated discs are commonly used on front wheels of heavier vehicles due to their ability to dissipate heat more effectively, ensuring better performance and longevity. Our Advantages:

A home electric vehicle charger is a device that provides convenient charging for electric vehicles. We can install and use it at home. Common home chargers include wall-mounted charging stations and portable chargers, such as QINGYUAN's portable charger, which supports a variety of voltage and current specifications and is suitable for electric vehicles compatible with J1772. When we choose a home charger, we need to consider factors such as charging speed, installation space, and connection method.
