Abstract
A machine component is formed of a coalesced metal body of multiple zones of material having at least one high hardness surface, along with high yield strength and good thermal conductivity. The coalesced metal body can have a zone of steel and a zone of copper, and have a transition zone in which the zones of steel and copper coalesce. The coalesced metal body has a machined surface on the zone of steel on a first side of the coalesced metal body. The zone of copper has a proximal boundary disposed proximal to, and separated by, the zone of steel, from the machined surface. Also the zone of copper has a distal boundary distal to the machined surface and proximal to a second surface of the coalesced metal body.
