Shapes

Neodymium Magnets are mostly non-standard parts. The shape and size of the magnet are generally processed according to customer needs, such as arc, square, cylinder, ring, other special shapes, etc., to facilitate a quick quotation, it's advisable to provide a drawing or sketch along with your inquiry.

Round / Disc / Countersunk

Ring / Tube

Rectangular

Irregular / Custom Shaped

Arc

Cylindrical

Surface Treatment

The coating of the magnet is another pivotal factor influencing the quotation. Different coatings offer distinct properties such as corrosion resistance, enhanced durability, or specific finishes. To ensure an accurate and prompt quotation, kindly specify your preferred magnet coating type in your inquiry
