Semi-metallic brake pads are brake pads that are generally composed of iron linings and friction materials. It replaces asbestos fibers with metal fibers. Semi-metallic brake pads primarily use coarse steel wool as a reinforcing fiber and an important compound. The asbestos type and the appearance (fine fibers and particles) of non-asbestos organic brake pads (NAO) are easily distinguished from each other. In addition, they are somewhat magnetic. Semi-metal based friction materials have the following primary characteristics:

1. Very stable below the conflict coefficient. No thermal degradation, good thermal stability.
2.semi-metallic brake pads have good wear resistance. Its service life is 3-5 times that of asbestos friction materials.
3. It has good conflict performance under high load, and the conflict coefficient is stable.
4. Has good thermal conductivity. The temperature gradient is small. Especially suitable for small disc brake products.
5. Low braking noise.
The relevant features of semi-metallic brake pads are introduced here, I hope to help you.
