About Neodymium Round Magnets

A To Z Magnet Mfg. Co. ventured in the business in the year 2005 as a Supplier, Trader, exporter, manufacturer and Importer of Superior Neodymium Magnets, Ferrite Magnets, Alnico Rod Magnets, Samarium Cobalt, Clamping Magnets, Pot Magnets, Fridge Magnets, NdFeB magnets, Rare earth magnets, Round magnets, Lifter Magnet, Grill Magnet, Channel Magnet, Drawer Magnet, and many more. Being a quality arranged firm, we attempt to give brilliant magnet with impeccable immaculateness and unwavering quality.

Exceptional Magnetic Performance

Built from high-grade NdFeB, our round neodymium magnets offer outstanding pulling force, capable of handling several kilograms depending on the size. With grades available up to N52, they deliver maximum energy products as high as 52 MGOe, making them the go-to choice for demanding industrial and scientific applications.

Engineered Coating & Corrosion Resistance

A nickel-copper-nickel coating (approximately 1015 microns thick) ensures reliable surface protection and enhanced durability. While the magnets are resistant to minor corrosion, it is recommended that they be used in dry indoor environments or secured with a protective barrier to maintain long-term performance.

Precision and Customizability

Manufactured to a strict 0.05mm tolerance, these magnets offer consistent quality and fit for projects that require high precision. Custom sizes, magnet grades, and coating options are also available, catering to diverse application needs across industries such as electronics, education, and manufacturing.

FAQs of Neodymium Round Magnets:

Q: How should neodymium round magnets be stored for safety?

A: Store neodymium round magnets away from electronic devices, pacemakers, and magnetic media, as their strong magnetic fields can cause damage or interference. Keep them in dry, indoor environments to avoid corrosion, and consider using protective padding to prevent chipping due to their brittle nature.

Q: What is the typical process for selecting the right neodymium magnet size and grade?

A: Begin by determining the required magnetic force for your specific application; larger magnets and higher grades (N52) offer greater pulling strength. Take into account the available space, operating temperature (most up to 80C, some up to 200C), and environmental exposure to choose the appropriate size, thickness, and coating. Customization is also possible upon request.

Q: When is additional surface protection necessary for these magnets?

A: Additional surface protection, such as specialized coatings or housings, is necessary in humid, damp, or corrosive environments. Although the nickel-copper-nickel coating provides good corrosion resistance, these magnets are ideally used in dry indoor settings to retain optimal performance over time.

Q: Where are neodymium round magnets commonly applied?

A: These magnets are widely used in industrial assemblies, scientific and educational experiments, sensors, electric motors, holding and lifting mechanisms, and craft projects. Their compact size, high magnetic strength, and precision make them suitable for both professional and creative uses.

Q: What benefits do nickel-plated neodymium magnets offer over alternatives?

A: Nickel-plated neodymium magnets provide superior magnetic force in a compact form factor, delivering enhanced holding power compared to ferrite or AlNiCo magnets. The triple-layer protective coating increases durability and offers moderate corrosion resistance, making them reliable for numerous technical applications.
