Description

Wet copper-base friction material is that taking copper as main component and made by powder metallurgy method, which is used in wet clutch or wet brake. It is stable in friction properties, low in operation noise, smooth in engagement, can be used in multi-plate clutch, with big transmitting torque. Brake and clutch applying this material has complex structure.

Application

Wet copper-base friction material is widely used in ship, constructional machinery, heavy automobile, tractor, pressure machine and special vehicle etc.

Qualification Certificate

‘Wet copper-base P/M friction disc and manufacturing method’ wins patent of invention in the country.
