摘要： The technical field of this invention relates to an Al-based bearing alloy and a slide bearing that uses the Al-based bearing alloy. The technical problem of the invention is to provide an Al-based bearing alloy that exhibits high corrosion resistance and in which high strength is maintained for a long period of time even in a high temperature environment, as well as a slide bearing that uses the Al-based bearing alloy. As means for solving the problem, an Al-based bearing alloy (10) includes an Al matrix (11), and acicular compounds (12) which are needle-shaped that precipitate at a plurality of sites in a structure of the Al matrix, and that have a minor diameter and a major diameter.

摘要： Provided is a sliding material (1) including a substrate (2); and a copper alloy layer (3) bonded to the substrate (2). The copper alloy includes 2.0 to 15.0 % by mass of tin. The copper alloy layer (3) includes a sliding body part (6) including a sliding surface (8), and a gradient region (5) including a bond surface (7) with the substrate. A tin concentration in the gradient region reduces from the sliding body part (6) toward the bond surface (7). A method for producing the siding material is also provided. The method includes: preparing the substrate having a first surface and a second surface opposite to the first surface; melting the copper alloy; casting the molten copper alloy on the first surface of the substrate; and solidifying the copper alloy unidirectionally by cooling the substrate from the second surface by a coolant.
