Wet Copper-Base Friction Material Used In Wet Clutch Or Wet Brake

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.

Main Data

1. Dynamic friction coefficiency: 0.05~0.08 (pressure sintering method); 0.06~0.09 (sprinkling method)
2. Static friction coefficiency: 0.11~0.15 (pressure sintering method); 0.11~0.15 (sprinkling method)
3. Wear rate: ≤1×10^-8cm³/J (pressure sintering method, sprinkling method)
4. Permissible specific pressure: 3.5~6.0 MPa (pressure sintering method); 2.5~6.0Mpa (sprinkling method)
5. Permissible energy load: 18000~45000 (pressure sintering method); 18000~45000 (sprinkling method)
