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.
We provide assembling service for magnets and magnetic products. Combined with the use environment and technical requirements of the products, we’ll design special assembly fixtures, use the suitable glue for the application of products, train skilled workers for assembling. Customer could nominate the brand and model for glue, it’s up to the materials the magnets are applied with. Customer could provide their magnets or we provide the whole product.
For more information, please contact our experts.
From DIY projects to crafting, model making, clothing manufacturing, OEM components, medical & scientific equipment, automotive parts and much more. Disc magnets are used frequently in holding applications where a magnet will be placed inside a drilled hole.
