Industrial Magnetics Inc. (IMI) announces a January, 2014 move to the exclusive use of 52 grade MgOe rare earth material1.
“Ten years ago we led the way in bringing 50 MgOe to the market in all of our 1-in. round circuit configurations (round circuits in larger ODs featured 45 MgOe). I am proud that we have made another significant step forward, with an upgrade to 52 MgOe rare earth materials for all IMI products featuring round magnetic circuitry,” said Dennis O’Leary, president IMI. “This is beneficial in that it offers a higher likelihood of capturing ferrous and weakly magnetic metal contaminants, resulting in cleaner product. It also provides a benefit to the processing stream at the plant level in the form of better capital equipment protection and assistance with critical control points.”
Two products on which IMI customers will see significant improvements are the Bullet and LTH, by way of the 52 MgOe material coupled with magnetic modeling software that has optimized the circuit configuration. Designed for pneumatic applications and currently testing out at a nominal pull strength of 11 lb on a ½-in. ball, the Bullet will now pull 22 lb. Featuring a 3-in. OD circuit and designed for product with challenging flow characteristics and a tendency to bridge, the LTH (Large Tube Housing) currently pulls 6 lb on a ½-in. ball, but the new design will also pull 22 lb. This reflects 100% and 365% increases in pull strength, respectively.
“In the big picture, IMI is simply being consistent with our goal of staying ‘above the noise’ by only offering what we feel is the strongest, most stable and commercially available rare earth material,” said O’Leary. “We don’t see the value proposition in muddling the marketplace with multiple and inferior strength levels of rare earth materials versus just providing the best.”
1MgOe refers to “Mega (million) Gauss Oersteds”, a unit of measure typically used in stating the maximum energy product for a given material; the higher the grade the stronger the magnet.
