Summary:The actuator (1) has a coil (6), and a magnetic reflux arrangement (2) comprising a magnetic reflux element (3) made of material i.e. duplex steel, with a biphasic structure. The magnetic reflux arrangement comprises ferritic and austenitic portions and austenitic and martensitic portions, which are formed by deformation of the austenitic portions. The magnetic reflux element is designed as a one-piece component and a tubular sleeve. The magnetic reflux element in an axial direction partly covers an inner pole (7) and an armature (8).
