LORD magneto-rheological (MR) fluids can respond instantly to varying levels of a magnetic field precisely and proportionally for controllable energy-dissipating applications, such as brakes, shocks and dampers. When exposed to a magnetic field, the rheology of LORD MR fluids (MRF) reversibly and instantaneously changes from a free-flowing liquid to a semi-solid with controllable yield strength. Response time for all LORD MR fluids is <5 ms; however, exact time is dependent on device design. All of our fluids are gray in color and redisperse easily with proper agitation. The iron particles contained in the fluid are between 1 to 20 microns.
