Properties:

  • material with good antifriction properties;
  • highest wear resistance of the continuous casting materials.

Application:

  • machine tool spindle bearings, which require the highest precision e.g.;
  • precision turning lathes;
  • grinders and gears;
  • piston pin bushes;
  • press bearings;
  • high stress spindle nuts;
  • high speed warm wheels and rims.
