摘要:
A method of making an aluminum alloy plate for bearing which is made by cladding a bonding layer comprising a pure aluminum or an aluminum alloy excluding Sn onto a bearing alloy layer comprising an aluminum alloy containing Sn. The method includes the steps of fitting a concave portion of a first roll in a convex portion of a second roll, the first roll having both axial ends with large diameter portions respectively, the second roll having both axial ends with small diameter portions respectively, and passing superposed plates formed into the bearing alloy layer and the bonding layer respectively through a roll gap defined between the concave and convex portions and closed by the large diameter portions of the first roll so that the plates are rolled down at a reduction ratio not less than 50% while both widthwise ends of each plate is restricted by the large diameter portions of the first roll respectively such that the bonding layer is cladded onto the bearing alloy layer.
