What are Semi-metallic brake pads? What are the characteristics of Semi-metallic brake pads? In fact, it is a brake pad that is generally composed of an iron lining plate and a friction material. It replaces asbestos fibers with metal fibers. Semi-metal brake pad material A non-asbestos friction material developed in the early 1970s. Semi-metal brake pads (semi-metal) primarily use coarse steel wool as a reinforcing fiber and an important mixture. 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) It is very stable below the conflict coefficient. No thermal degradation, good thermal stability.
(2) 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) Semi-metallic brake pads have good thermal conductivity. The temperature gradient is small. Especially suitable for small disc brake products.
(5) Low braking noise.
The characteristics of Semi-metallic brake pads are introduced here, I hope to help you.
