Neodymium Magnets N50 Block 2 inch x 1 inch x 0.5 inch Thick NdFeB Magnet for Wind Turbine Generators - Epoxy+Copper+Nickel Triple Layer Coated

Super Powerful Neodymium Magnets N50
BrMax: 14500 gauss
Epoxy+Copper+Nickel Triple Layer Coated for maximum protection against corrosion.






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; N50 grade magnets with Epoxy+Cu+Ni Coating offer better performance and durability than other magnets.




Grade Makes a big difference ! The higher the grade, the stronger the magnet

N50 is stronger than N48, N45, N42, N40, N38 and N35
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-Nickel-Copper-Nickel quadruple layer offers maximum corrosion resistance and durability.

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 magnets), a type of rare earth magnets, are the permanent magnet made from neodymium, iron, boron and other minor elements.

Super strong neodymium magnets N50, stronger than N48, N45, N42, N40, N38 and N35

BrMax: 14500 gauss

Magnetized through the Thickness 0.5", poles are on the two 2x1" surfaces

Just as is advertised, these are SERIOUSLY STRONG magnets!! Wear good leather gloves if handling more than one at a time as they WILL damage fingers/flesh if you're not careful!

As for the coating, I found that it nicks or scratches pretty easily when contacted with hard metal surfaces. My advice is to make certain you know where you want to place them ahead of time then don't try to move them very much once they are in place.

I purchased 12 of these to use in a wind powered alternator which isn't yet completed, so I can't yet comment on how they will perform in that application.
