Introduction to materials and manufacturing processes:Copper metal Sintering - An improvement over the traditional copper sintering process, it reduces the hardness of the friction material. The friction material does not contain iron components, effectively lowering the probability of noise occurrence. At the same time, it retains the copper sintering to ensure the sheet's consistent extremely long service life and suitability for extreme working conditions. It can withstand extremely long periods of continuous high braking temperatures, with stable braking force output and a long service life. Disadvantages: The probability of noise occurrence is relatively higher than the above two models, and the low-temperature performance is relatively weak (at the beginning of the low-temperature environment, you need to pinch the brake more often to increase the temperature).
