It is a cooper based sintered friction material facing for dry running applications. A special combination of alloy particle and copper gives high friction coefficient and smooth engagement. t has the following advantages: high temperature resistance, very smooth engagement, high Cutwear resistance, high and stable level of friction coefficient, negligible wear of mating material, easy replace, and safety. It is for brake system in wind turbine, high speed train, highly loaded clutches. Now, we have many clients all over the country. We can process according clients' drawing.
