Copper-base Friction Material

Copper-base friction material takes copper as main component and adds alloy elements to strengthen the basis material, uses elements of graphite, lead, silicone dioxide etc to improve friction wearing performance, and applies powder metallurgy press sintering or sprinkling sintering procedures to finish the friction material, which has features of high temperature resistance and perfect friction performance. It can be used in dry or wet working conditions.

Iron-base Friction Material

Iron-base friction material takes iron as main component, adds some non-metallic elements and is finished via power metallurgy method. It is mainly used in dry brake. The material is high in static and dynamic frictional coefficiencies, large in torque transmit, high temperature resistance, and suitable for severe working condition. Brake and clutch using the material is simple in structure, which can form friction pair with plain steel or sintered materials.

Paper-base Friction Material

Using paper-making technology, the paper-base friction material is produced by making sorts of reinforced fibres, friction components and anti-friction components into pulp suspension, making friction paper, then impregnating resin, solidifying and sticking onto steel core plate. It possesses features of high and stable friction coefficiency, close static and dynamic friction coefficiencies, smooth and soft engagement, low noise and strong power absorbing capabilitiy, widely used in applications of wet clutch and brake.
