wherein the foam forms an annular region around an entire circumference of the hub, and

wherein the annular region extends over an entire axial extension of the hub.

2. The centrifuge rotor according to claim 1 , wherein the porous metal or the porous metal alloy is a foam material.

3. The centrifuge rotor according to claim 1 , wherein the metal or the metal alloy includes at least one component selected from the group of aluminum, iron, copper, magnesium, nickel, titanium or alloys thereof or brass.

4. The centrifuge rotor according to claim 1 ,

wherein the armoring includes a fiber-reinforced plastic material.

5. The centrifuge rotor according to claim 1 ,

wherein the armoring is arranged in a recess provided in the rotor body,

wherein the armoring has a larger radial width at least in a portion of the rotor body located radially farther outside than in a portion of the rotor body located radially farther inside,

wherein the centrifuge rotor includes a hub arranged at the rotor body,

wherein the hub is fixated in the rotor body through annular foam encasement,

wherein the foam forms an annular region around an entire circumference of the hub, and

wherein the annular region extends over an entire axial extension of the hub.

6. The centrifuge rotor according to claim 1 ,

wherein the porous metal or the porous metal alloy has a medium pore size of 10 μm to 500 μm, and

wherein the pores are sealed.

7. The centrifuge rotor according to claim 1 , wherein the armoring essentially completely encloses a circumference of the rotor body.

8. The centrifuge rotor according to claim 1 ,

wherein a contour ring for a form locking connection with a centrifuge lid is arranged at the rotor body, and

wherein the contour ring is configured as a separate element having a higher strength than the porous metal or the porous metal alloy.

9. The centrifuge rotor according to claim 1 ,

wherein the armoring includes a fiber-reinforced material,

wherein the fibers include at least one material selected from the group of carbon fibers, mineral fibers, ceramic fibers or plastic fibers or mixtures thereof, and
