Features include
Disc magnets are round in shape and defined by their diameter being greater than their thickness. They have a wide, flat surface as well as a large magnetic pole area, making them the ideal choice for all types of strong and effective magnetic solutions.
-Consists of an alloy of Neodymium, Iron and Boron
-Widely served for both industrial and civil applications
-Chip or break if felt onto a hard object from height
-Can be machined to different thickness
-Can be magnetized through axial or radial direction
-Operating temperatures vary among materials, e.g. N/M/H/UH/EH/AH grades. You could visit our chart of material properties for reference.
