Abstract
The invention relates to a sliding bearing composite material with a hard metal support layer and a metallic sliding coating which is roll-bonded onto said support layer. The inventive sliding bearing composite is made of an aluminum alloy with tin comprising 10 to 20 percent by mass and with additions of copper and nickel. The sliding layer is in direct contact with the sliding mate. The sliding bearing composite material is thus improved with respect to the loading capacity and plasticity in that the aluminum alloy is comprised of tin, copper, nickel and remaining aluminum, the copper and nickel each have a percentage by mass of 0.2 to 2, and the ratio of percentage by mass of copper to the percentage by mass of nickel is between 0.6 and 1.5.
