Some Reasons Dyprosium is Needed in EVs

Just some real quick reasons for buying NTU. As it seems some might be misinformed. Neodymium (NdFeB) is one of the most commonly used in motors for hybrids vehicles and EVs. Neodymium magnets have higher remanence, along with much higher coercivity and energy production, but often lower Curie temperature than other types. Special neodymium magnet alloys that include terbium and dysprosium have been developed with higher Curie temperature, allowing them to tolerate higher temperatures of up to 200°C. Normal NdFeB magnets, once surpass 80 degrees Celsius (176 degrees Fahrenheit), irreversible loss of magnetization occurs. This decreases torque of engine, this is bad, in case there is confusion. Because of the RE magnet properties, no other magnet material can match their high strength performance. “You cannot really replace RE magnets,” says Dan Vukovich. Dan Vukovich graduated with a B.S. in Mechanical Engineering, he started his career designing permanent magnet based motor systems. He became so passionate about potential applications using magnets he started a company. One of the key reasons for his success has been his ability to forecast the supply and demand of critical rare earth materials (I don't see this guy using fridge magnets in an EV). In 2011, China cut its exports of Rare Earth Elements to the rest of the world to meet its own demands, triggering fears of a global shortage. Rare earth magnet values skyrocketed accordingly: They reached a high point of $2,200/kg from an earlier $130/kg - did someone mention the start of a trade war ?? Anything above 300 parts per million is considered highly concentrated, therefore 'Rare Earth'. I hope this helps people with being more educated.
