Semi-metal brake pads are brake pads that are generally composed of iron linings and friction materials. It replaces asbestos fibers with metal fibers. The semi-metal brake pad material is a non-asbestos friction material. Semi-metal brake pads (semi-metal) primarily use coarse steel wool as a reinforcing fiber and an important mixture. In addition, they are somewhat magnetic.
Semi-metal-based friction materials have the following primary characteristics:
- Very stable below the conflict coefficient. No thermal degradation, good thermal stability.
- Good abrasion resistance. Its service life is 3-5 times that of asbestos friction materials.
- It has good conflict performance under high load, and the conflict coefficient is stable.
- Has good thermal conductivity. The temperature gradient is small. Especially suitable for small disc brake products.
- Low braking noise
