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.
