Coatings for Neodymium Magnets

Coatings for Neodymium Magnets

Nearly every neodymium magnet will be plated or coated and, as the most powerful permanent magnet available, they are used in many different applications. However, they possess physical characteristics that require them to be plated or coated in order to protect them from damage. In their raw form, neodymium magnets are quite brittle, and as…

AlNiCo Magnets and Music Revolution

AlNiCo Magnets and Music Revolution

AlNiCo pickup magnets played a huge part in the development of modern electric guitar sounds.  Guitar manufacturers and musicians discovered that even on the same guitar, switching out different AlNiCo alloys resulted in drastically different musical tones.  Indeed, the use of certain AlNiCo pickups is responsible for the signature sounds associated with 50s and 60s…

The History of Neodymium Magnets

History of Neodymium Magnets banner

The origin of the neodymium magnets dates back to 1885 when Carl Auer von Welsbach, an Austrian scientist and inventor, separated didymium into the new separate elements neodidymium (“new didymium”) and praseodidymium (“green didymium”).  In time, the element names would change to neodymium and praseodymium. Neodymium (Nd) is the fourth member of the lanthanide ‘rare-earth…

Magnets and the Curie Temperature

Curie Temperature

The term “Curie temperature (Tc)” or “Curie point” gets frequently mentioned when discussing magnets and magnetic properties.  The Curie temperature relates to the maximum temperature a material can reach before losing its magnetic properties.  On reaching a magnetic material’s Curie temperature, the spontaneous magnetisation in the material drops to zero.  At this point, the material…

Ferrite Magnet Price Trends

Ferrite-Prices-Aug-22

Updated 4th August 2022 The Strontium Ferrite (SrFe12O19) permanent magnet (also known as a ceramic magnet) is the most commonly used magnet material. Each Ferrite Magnet consists of approximately 90% iron oxide and 10% strontium carbonate. Since March 2022, the price of Strontium Carbonate has stablised, although it remains 2.4 times higher than in January…
