Abstract
A magnetorheological fluid comprising a mixture of soft and hard iron particles, an organic based carrier fluid, and optional additives such as anti-friction, anti-wear, or surfactants unexpectedly have improved durability when used in devices for control vibration and/or noise, for example, shock absorbers, elastomeric mounts, dampers, and the like.
