    If you are new to the magnet industry, then you are probably keen to understand the most common terms. We have collated some phrases in alphabetical order that are used in day-to-day discussions at LCM.

    Alloy

    Two or more metals with characteristic properties.

    Annealing

    A process when a material is heated and cooled to improve its performance.

    Anode & Cathode

    A piece of metal that is used for electrolysis or electrowinning.

    Bonded Magnets

    These magnets consist of two components, a non-magnetic polymer, and a hard-magnetic powder.

    Crucible

    This is used to hold a sample inside a high-temperature furnace.

    Electrolysis Metal Making

    A process that uses a direct current in an electric salt bath to melt metal at extremely high temperatures.

    EV

    Electric vehicle. There has been a lot of discussion at the moment around EVs as they require NdFeB permanent magnets to be manufactured. You may even hear of HEV which are hybrid electric vehicles.

    Ferroalloy

    This term is used when talking about various iron alloys with a high percentage of other elements.

    Ferromagnetism

    This is the process when certain materials form permanent magnets.

    Hard magnetic materials

    These are also known as permanent magnets; they retain their magnetism after being magnetised.

    Jet Casting

    A process that casts molten metal into thin ribbons for bonded magnet production.

    Lanthanides

    Another name for rare earth metals.

    NdFeB

    Neodymium iron boron. Permanent magnets based on NdFeB are the most powerful permanent magnets available commercially.

    Minor Metals

    This term is used when speaking of metal which is a by-product of melting base metals

    Rare earth elements

    Seventeen elements which have a deceiving name as you can find them in the earth’s crust across various countries including China, Brazil, Australia, and United States. They are split into two categories: light and heavy rare earths. Each element has individual properties and is used across various industries.

    Rare earth oxides

    These are readily formed from rare earth elements.

    Sintered magnets

    A sintered magnet is produced by a powder metallurgical process.

    Strip Casting

    A process that casts molten metal into thin flakes for sintered magnet production.
