Neodymium Magnets 2 inch x 1 inch x 0.5 inch Thick N42 Block Rare Earth Neodymium Magnets Epoxy+Copper+Nickel Triple Layer Coated - Stronger than N35, N38 and N40

Neodymium Magnets are the world's strongest magnets. All magnets are not created equal! Applied Magnets offers the highest quality neodymium magnets with consistent performance at lowest price. Our strong neodymium magnets are designed & manufactured to meet stringent quality standards using the latest technology.

Neodymium magnets (also known as Neo, NdFeB, NIB or super magnet) , a type of rare earth magnets, are the permanent magnets made from neodymium, iron, boron and other minor elements.

Grade N42 is the recommended Grade due to its cost effectiveness over N35/N38/N40 in Hugh Piggott's new book "A Wind Turbine Recipe Book".
 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

For wind generator magnets, coating and performance are the most important things to consider, we recommend Epoxy+Copper+Nickel 3-layer coating for long term durability under all weather conditions, we don't recommend Epoxy single layer coating, please read details below. To have better performance for your wind generator, the higher grade the magnets, the better; we recommend at least N42 or higher grade for high performance.




Grade Makes a big difference ! The higher the grade, the stronger the magnetN42 grade vs. N35/N38/N40

N35 is the lowest NdFeB neodymium magnet grade on the market, we don't carry N35 grade due to its lower performance making our N42 grade the better value.

N38 and N40 are lower grades compared to N42.



Coating Makes a big difference !

Hugh Piggott talks about wind turbine failure caused by magnet corrosion due to bad coating in his book:

"........ the magnets themselves that can lead to a major failure in under 5 years............. Once the protective plating on the magnet is punctured, the magnet corrodes and swells gradually."

3-layer coating (Nickel + Copper + Nickel and Epoxy + Copper + Nickel) vs. Epoxy single layer coating

Epoxy single layer coating is THE LEAST durable coating from our experience.
3-layer coating is much more durable than Epoxy single layer coating because Epoxy single layer coating is a thin layer of plastic and quicker to wear off, even a scratch can damage the coating easily.

More importantly, magnets with 3-layer coating have superior cracking and chipping resistance in comparison to magnets with Epoxy single layer coating. Customer beware of the magnets with the inferior Epoxy single layer coating.



Epoxy+Copper+Nickel 3-layer coating vs. Nickel+Copper+Nickel 3-layer coating

Epoxy + Copper + Nickel 3-layer coating has superior Corrosion Resistance and excellent adhesion to metal surface than Nickel + Copper + Nickel coating, this coating is ideal for bonding metal. Nickel+Copper+Nickel coating provides protection against moisture and oxygen but is prone to corrosion in salt and acidic conditions.

Epoxy-Copper-Nickel triple layer offers maximum corrosion resistance and durability.
