What is the difference between various friction plate raw materials?
The main materials of the friction plate are semi-metal, NAO, ceramic, quartz, etc.:
1. Low-metal friction plate means that the iron content is less than that of semi-metal friction plate. In fact, it can be regarded as a kind of semi-metal friction plate.
2. NAO is an asbestos-free organic friction plate, which is cheap and light in weight. The technology is mature but the braking effect is not good
3. The ceramic friction pad forms a stable ceramic interface on the surface of the brake pad during the braking process. There is no real ceramic brake pad in China. One is that the temperature during braking cannot be reached, and the other is the formation of Without a stable ceramic interface, there are few at present, and the technology is not yet mature, but the price is not expensive.
4. The semi-metallic friction plate contains about half of the material containing iron, usually steel wool and iron powder. The disadvantage is that it is heavy on the plate, heavy, and the price is higher than NAO.
5. Graphite material refers to carbon-carbon composite or carbon-ceramic composite materials. Graphite friction material is the most high-grade friction plate, which is light in weight and excellent in heat dissipation, but it is more expensive.
Generally speaking, all kinds of friction plate materials have their own advantages and disadvantages. There is no best material, only the most suitable one.
