Claim:
A shaped part produced by pressing and sintering a pulverulent starting material, the shaped part comprising: a basic body formed with a multiplicity of elevations and a surface contour between said elevations; said elevations having a height h from said surface contour of said basic body to an end contour of said elevations, each of said elevations, in cross section, having two inclined side flanks extending from said end contour of said elevation, via rounded corner portions having a radius r and r′, respectively, into curved portions having a radius R and R′, respectively, with a transition therebetween having a tangent with an angle of inclination α and α′, respectively, with regard to said surface contour lying in a range of 95° to 135°, and said curved portions merging into said surface contour of said basic body; said radius R and R′ lying in a range from 0.15 to 1 mm and said height h being dimensioned such that a ratio R:h and a ratio R′:h lies in a range of 0.5 to 1.
