  • Aluminum Nickel Cobalt – AlNiCo magnets

    The Alnico (Aluminum, Nickel, Cobalt) magnets was introduced in the 1930’s. It’s characterized by excellent temperature stability, high residual induction, and relatively high energies. These were the first materials specifically designed for permanent magnets to be used in meters and instruments...

  • Bonded NdFeB magnet

    Bonded NdFeB magnets are manufactured with melt spinning of a thin ribbon of NdFeB alloy. This ribbon contains randomly oriented Nd2Fe14B nano-scale grains. Then, the ribbon is pulverized into particles and mixed with a polymer. At last, it is compressed into bonded neodymium magnets. Bonded NIB ...

  • Sintered NdFeB magnet

    As lanthanide series of elements in the periodic table, sintered neodymium magnets (sintered NdFeB magnets or sintered NIB magnets) are also known as rare earth magnets. Featured by outstanding magnetic properties, they are the most powerful magnets used today. Sintered NdFeB magnets are manufact...

  • Platings/Coatings/Adhesives

    [Q] Why are most neodymium magnets plated or coated?[A] Neodymium magnets are composed mainly of Neodymium, Iron, and Boron. If neodymium magnets are not plated, the iron in the material will oxidize very easily if exposed to moisture. Even normal humidity will rust the iron over time. To protect...

  • Separating large neodymium magnets

      Remember, magnets, particularly neodymium magnets are very hard and brittle. Don’t be fooled by the shiny exterior, they may look tough like steel but if two magnets slam together they will crack and break.[Q] I have metal dust all over my magnets. How can I remove it?[A] Using adhesive ta...

    What is magnetism?

    Science is our understanding of how the world works—and generally the world works fine whether we understand it or not. Take magnetism, for example. People have known about magnets for thousands of years and they’ve been using them practically, as compasses, for almost as long. The ancient Greeks...

  • The Permanent Magnet

    The Permanent Magnet

    Centuries ago, it was discovered that certain types of mineral rock possessed unusual properties of attraction to the metal iron. One particular mineral, called lodestone, or magnetite, is found mentioned in very old historical records (about 2500 years ago in Europe, and much earlier in the Fa...
