A compound roll (20) includes a sintered inner core (22) of a first cemented carbide and at least one sintered outer sleeve (24) of a second cemented carbide disposed around the inner core. The outer sleeve and inner core each have a joining surface (26,28), wherein when the inner core and outer sleeve are assembled each joining surface is brought into contact to form a bonding interface (30) there between. When the assembled sintered inner core (22) and sintered outer sleeve (24) are heated to a predetermined temperature the sintered inner core and sintered outer sleeve are fused together at the bonding interface (30) to form the unitary compound roll (20). In order to reduce the overall cost of the compound roll (20), a lower cost cemented carbide, or a cemented carbide with a lower density can be used for the inner core and fused to a sintered outer sleeve of a virgin cemented carbide, thereby reducing the powder cost and/or reducing the overall mass of the compound roll itself.
