There's a new development in magnets, and I will post anything I find in this thread.
Iron Nitride magnets / Fe16N2
No rare-Earth elements, cannot be restricted by China
Stronger than Neodymium per volume
Should cost less to produce than neo's
Environment-friendly raw materials,
Temp range <150C
"...Giant saturation magnetic flux density (2.9 T)..."
"...Its coercivity temperature coefficient (~ 0.4 Oe/°C) in the range of 27–152 °C is two
orders of magnitude lower than that of commercial NdFeB magnets (e.g. N40 ~ −81.9 Oe/K)..."
"...The theoretical magnetic energy product for this iron nitride (Fe16N2) magnet is 130 mega gauss Oersteds, which is more than twice the maximum reported magnet energy product for a rare-earth neodymium magnet...."
