B Non-asbestos friction materials are divided into the following categories:
A semi-metallic friction material used for disc brake pads for cars and heavy duty vehicles. Its material formula usually contains about 30% ~ 50% iron metal (such as steel fiber, reduced iron powder, foam iron powder). Semi-metallic friction materials are thus named. Is the earliest replacement of asbestos and the development of a non-asbestos material. Its characteristics: good heat resistance, high absorption power per unit area, large thermal conductivity, can be applied to the braking requirements of the automobile in high-speed, heavy load operation. However, it has some disadvantages such as loud braking noise and brittle edge and corner.
