Magnet Shape

Ring, Disc, Cylinder, Arc, Block, Stick, Cuboid, Cube, Bar, Countersunk, Segment, Trapezoid and other abnormal shape according to customers' requirement. Customized shapes are available.


Double Nickel, Nickel Copper Nickel, Zinc, Gold, Copper, Chemical, PTFE, Parylene, Everlube, Passivation,Tin, Aluminium, Teflon or Epoxy, depending on the application.

Technology Advantage

Depending on advanced R&D center, Quality control team and professional machining technicians, we can surpass our competitors in the stability of quality and superiority of property.

Tight tolerances

Standard tolerances are ± 0.1 mm. If grinded ± 0, 05 mm/± 0, 03 mm. Tighter tolerances are available on request.

Delivery Advantage

The lead time must be 7-10 days quicker than industry average because of more flexible machine process control.


1. Electronics – Sensors, hard disk drives, sophisticated switches, electro-mechanical devices etc.

2. Auto Industry – DC motors (hybrid and electric), small high-performance motors, power steering.

3. Medical – MRI equipment and scanners.

4. Clean Tech Energy – Water flow enhancement, wind turbines.

5. Magnetic Separators – Used for recycling, food and liquids QC, waste removal

6. Magnetic Bearing – Used for highly sensitive and delicate procedures in various heavy industries.

1.Q:Will magnets lose their power over time?
A:Do lose a very small fraction of their magnetism over time. For example, SmCO magnet has been shown to be less that 1% over a period of ten years.

2.Q:Can a magnet that has lost its magnetism be re-magnetized?
A:If the magnet has not been damaged by extreme heat, it can be re-magnetized back to its original strength.

3.Q:What are the standard industry definitions of "North" and "South" Pole?
A:The North Pole is defined as the pole of a magnet that, when free to rotate, seeks the North Pole of the earth. Similarly, the South Pole of a magnet seeks the South Pole of the earth.

4.Q:Can a particular pole be identified?
A:Yes, the North or South Pole of a magnet can be marked if specified.

5.Q:What does "orientation direction" mean?
A:Magnets have a “grain” in that they can be magnetized for maximum effect only through one direction.

6.Q:Does stacking magnets together make them stronger?
A:Yes, stacking two or more magnets together will act similar to a single magnet of the combined size.

7.Q:Why are most neodymium plated or coated?
A:Neodymium magnets are mainly constructed of Neodymium, Iron and Boron. Iron can oxidize very easily when exposed to moisture and will rust over time.
