Bunting Supports Brazilian University Understand Shape Anisotropy and Magnetic Texture
Bunting is supporting an international study into shape anisotropy and magnetic texture determination in anisotropic and isotropic AlNiCo magnets. The research project is being undertaken by Professor Marcos Flavio de Campos, Leonardo Martins da Silva and José Adilson de Castro of the Federal Fluminense University, along with Dr Sergio Antonio Romero of the University of…
Read MoreUnderstanding Magnetic Permeance Coefficient
Firstly, it is important to understand that the maximum working temperature of a NdFeB magnet is not defined by the material grade! It is essential to calculate the magnetic permeance coefficient to establish what grade of material you need. The two examples compare the same magnet but with different thicknesses, one at 30mm and one at…

Read MoreAlNiCo 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…
Read MoreThe History of Neodymium Magnets
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…
Read MoreMagnets and the 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…
Read MoreEverlube Coating Protects Neodymium Magnets
The new Everlube anti-corrosion magnet coating combats the increasingly arduous working environments for magnets and magnetic components. The Everlube coating prevents oxidation and deterioration of high-powered permanent neodymium rare earth magnets. The Everlube coating was originally developed as a brand of dry film lubricant products specifically designed to enhance and improve the performance of critical…
