XtraFlux® is our trademark for the type of magnet we use in all our products. XtraFlux® magnets are made from a Neodymium rare earth compound. They are manufactured from three main elements Neodymium, Iron, Boron and a few minor transition metals. The elements are melted together and then milled into a fine powder. They are called "rare earth" magnets because the primary element Neodymium is classified as such in the lanthanides section of the Periodic Table of the Elements.
The powder compound is dry pressed into the shape we need while being magnetically oriented. The material is sintered (high heat and pressure), aged and cut to dimension. Each disc is then milled, nickel coated and magnetized to the proper MGO rating. As a final step, each magnet is individually tested and inspected to certify that it meets the intended rating and quality.
ATTRIBUTES OF NEODYMIUM MAGNETS
XtraFlux® Neodymium magnets are extremely strong magnetically. Rare earth magnets do have another characteristic that is different from other type magnets, that being they are minorly brittle. Therefore they need to handled in such a way as to avoid dropping them or allowing them to snap together. They can chip or crack if handled improperly, however, they will not lose their magnetisim.
XtraFlux® Magnets exhibit:
- very high energy for size
- light weight
- nickel coating to prolong life
- very high resistance to demagnetization
- higher cost than other type magnets
Types Of Permanent
Magnets
Permanent magnets take many forms. Each type of magnet product has a different depth of magnetic field influence and this determines its magnetic effectiveness. Polarity alignment, such as (+) north, (-) south, alternating north/south checkerboard or north/south concentric patterns has not proven to be major effectiveness factors. A magnet’s strength is most important in determining depth of penetration of its magnetic field. The types of materials used to construct magnets determine their magnetic strength characteristics. The following chart shows the average comparative strength values, rated in gauss, for the most commonly used magnets.
