Slide parts, comprising a first part (1) made of an aluminium alloy having an Alumite layer formed on the slide surface thereof and another part (2) made of an aluminium alloy having a Fe-series wet-plated layer formed on the slide surface thereof, which is to be in contact with and slide on the slide surface of the former alloy part (1); and a method of the manufacture of the slide parts (1,2). The slide parts are made to be lightweight and are excellent in abrasion-­resistance and baking-resistance. The clearance variation due to changes in temperature is small, and the slide parts are suitable for use as reciprocating slide parts.
