摘要

The cam shaft adjusting unit (1) has cam shaft adjusting unit components, which are drive wheels (9), a stator (2) and a rotor (3). One of drive wheels, stator or rotor is partly manufactured from a hypereutectic aluminum based alloy. The aluminum based alloy has certain proportion silicon and contains traces of phosphorus. An independent claim is included for a method for manufacturing drive wheel, stator or rotor of cam shaft adjusting unit.
