What kind of iron particles are used in making LORD MR fluid?
A. We use a variety of iron particles depending on the fluid formulation to optimize magnetic properties and application performance. Carbonyl iron, which is made from the thermal decomposition of iron pentacarbonyl, is most commonly used in making MR fluids. Carbonyl iron particles are highly spherical in shape with sizes in the 1 to 10 micron range with an elemental iron content > 98%.
