Applications of magnetorheological fluids which have wide applications in automotive and structural engineering in dampers, clutches etc., have been widely studied. The cost of commercially available MR fluids is restricting its extensive use. In this paper, a stable MR fluid is developed using in-house technology at a fraction of cost at which the fluid is available commercially. The developed fluid is tested for on-state as well as off-state rheological properties in a fabricated MR damper prototype. The off and on-state characteristic of the fluid in terms of viscosity and damping force respectively is evaluated and compared with the commercially available MR fluid. This study has revealed that the developed MR fluid is following the same pattern for damping force as that of commercially available MR fluid and can be used in various commercial applications at highly reduced cost.
