Neodymium (Nd) is a rare earth element with an atomic weight of 60, typically found in the lanthanide section of the periodic table.
Neodymium magnets, also known as Neo, NIB, or NdFeB magnets, are the most powerful permanent magnets. Composed of Neodymium Iron and Boron, they exhibit exceptional magnetic strength.
Neodymium magnets are significantly stronger than ceramic or ferrite magnets, boasting about 10 times the strength.
Different grades of Neodymium magnets balance material capabilities and energy output. Grades impact thermal performance and maximum energy product.
No, Neodymium magnets maintain their strength without a keeper, ensuring long-lasting performance.
Poles can be identified using a compass, gauss meter, or another magnet's identified pole.
Yes, both poles exhibit the same surface gauss strength.
No, producing a magnet with just one pole is currently impossible.
Gaussmeters gauge magnetic field density on the surface, measured in Gauss or Tesla. Pull Force Testers measure holding force on a steel plate.
Pull force is the force needed to separate a magnet from a flat steel plate, using a perpendicular force.
Yes, the magnet's pull force represents its maximum holding capacity. Shear force is around 18 lbs.
Magnetic field distribution can be adjusted to focus magnetism in specific areas, enhancing magnetic performance.
Stacking magnets improves surface gauss up to a certain diameter-to-thickness ratio, beyond which surface gauss won't increase.
No, Neodymium magnets retain their strength throughout their lifetime.
Slide one magnet across another to separate them, using a table's edge as leverage.
Magnets attract ferrous metals like iron and steel.
Stainless steel, brass, copper, aluminum, silver are not attracted to magnets.
Coatings include Nickel, NiCuNi, Epoxy, Gold, Zinc, Plastic, and combinations.
Coating differences include corrosion resistance and appearance, such as Zn, NiCuNi, and Epoxy.
Yes, we offer unplated magnets.
Yes, most coatings can be used with glue, with epoxy coatings being preferable.
Effective painting is challenging, but plasti-dip can be applied.
Yes, poles can be marked with red or blue color.
No, heat will damage the magnets.
No, magnets are prone to chipping or fracturing during machining.
Yes, heat disrupts the alignment of atomic particles, affecting magnet strength.
Working temperatures vary by grade, from 80°C for N series to 220°C for AH.
Curie temperature is when the magnet loses all ferromagnetic ability.
Maximum operating temperature marks the point where magnets start losing their ferromagnetic properties.
Chips or cracks don't necessarily affect strength; throw away those with sharp edges.
Damp paper towels can be used to remove metal dust from magnets.
Magnets pose a low risk to electronics due to limited field reach.
Neodymium magnets are safe for humans, but large ones can interfere with pacemakers.
Yes, RoHS documentation can be provided upon request.
Air shipments require metal shielding for larger magnets.
We ship internationally through various carriers.
Yes, door-to-door shipping is available.
Yes, magnets can be shipped by air.
No minimum orders, except for custom orders.
Yes, we offer customization based on size, grade, coating, and drawings.
Molding fees and minimum quantities may apply to custom orders.
