    Abstract: The present invention relates to an aluminum alloy having low density and enhanced heat resistance. An aluminum alloy having improved high temperature physical properties comprises: magnesium (Mg) in an amount of about 7 to about 11 wt %, silicon (Si) in an amount of about 4 to about 8 wt %, copper (Cu) in an amount of about 0.5 to about 2 wt % and manganese (Mn) in an amount of about 0.3 to about 0.7 wt %, and a balance of aluminum based on the total weight of the aluminum alloy. Vehicle parts such as a piston, a housing and/or a bed plate of high power engine, to which the aluminum alloy may be applied, are provided as well.

    Abstract: A sliding device 1 is constituted of a swash plate 3 including a first sliding surface 3A and a semispherical shoe 4 sliding with the swash plate 3. The swash plate 3 is constituted of a base material 3B of high strength brass containing Mn and Si, and very small granular Mn—Si compounds 6 are exposed on an inside of the base material 3B and on the first sliding surface 3A (surface of the base material 3B). The above described swash plate 3 increases in exposure amount of the Mn—Si compounds 6 exposed on the first sliding surface 3A being the surface by applying etching to the base material 3B after cutting the base material 3B. The sliding device 1 which is favorable in seizure resistance at low manufacturing cost as compared with the conventional sliding devices can be provided.
