Pump housing of a magnetic and a non-magnetic material

A pump housing obtained by a method comprising:

• providing a first material;
• providing a further material;
• forming a pump housing precursor;
• wherein at least one first subregion of the pump housing is formed by the first material;
• and
• wherein at least two further subregions of the pump housing are formed by the further material;
• wherein the at least one first subregion and at least one further subregion alternate on a circumference of the pump housing;
• and
• heating the pump housing precursor at a temperature of at least 300° C.

A housing comprising a wall surrounding an interior region, wherein the housing has an inlet and an outlet,

• wherein the wall of the housing has at least one first subregion and at least one further subregion in at least one plane perpendicular to the longitudinal extension of the housing and wherein the at least one first subregion and the at least one further subregion alternate on a circumference of the pump housing;
• wherein the at least one first subregion comprises at least 60% by weight, based on the total mass of the at least one first subregion, of at least one nonmagnetic material,
• wherein the at least one further subregion comprises at least 41% by weight, based on the total mass of the at least one further subregion, of at least one ferromagnetic material,
• wherein the at least one further subregion in the plane and the at least one first subregion in the plane are adjacent and
• wherein the at least one first subregion and the at least one further subregion are connected to one another in a material-fitting manner.
