Abstract

A clad plate includes an aluminum plate and a hard metal plate joined together at side end surfaces thereof. Side end surfaces of an aluminum plate and a hard metal plate are jointed together via a nickel layer by pressure welding. A ridge and a groove formed in the side end surface of the aluminum plate are respectively engaged and joined, via the nickel layer, to a groove and a ridge formed in the side end surface of the hard metal plate, and an end portion of the nickel layer extends beyond the rear end portion of the side end surface of the aluminum plate and is jointed to the plate surface of the aluminum plate with the end portion exposed thereon. The average width W of the exposed portion of the nickel layer exposed on the plate surface is preferably from about 0.2 mm to about 1.5 mm.
