PTFE coated magnet rods consist of neodymium magnets, steel washers and PTFE shell. They are also called Teflon coated neodymium magnet rods. With PTFE shell, they are resistant to corrosion by strong acid and alkali solutions. Their surface magnetic field strength reaches 6000-7000 gausses, or higher as per requirements. In this article, PTFE coated magnet rods applied for test of magnetic impurities in Li-ion battery materials is described. A Test Method of Magnetic Impurities in Li-ion Battery Materials Magnetic impurities… Read More
