Disc Neodymium Permanent Magnets 20170124
N45 Small Neodymium Disc Magnets with 4 Poles with Au Coating

Look for Smallest 4-poles Magnetized N45 Disc Permanent Magnet:

There are three new sizes.
Material: N45 neodymium magnets
Coating: Ag/Ni-Cu-Ni/Au
Magnetized direction: 4-poles NSNS thickness diameter.
Besides, what’s the smallest you could make and still get four symmetrical quadrants with clear and clean inter pole boundaries just as they are now?

Neodymium Magnet Manufacturer  China Rare Earth Magnet Limited:
The smallest possible NSNS magnet size is diameter >4mm, thickness>2mm.
Diameter>4mm and thickness >2mm are both mandatory requirement, i.e. the size shall be D4x2mm.
Please check the following prices:

Ag/Au/Ni-Cu-Ni Coating of NdFeB Permanent Magnets:
I still have the coating of pieces in Ag plating. Seeing I now encase these in plastic, I think Nickel plating might be better.
Nickel plating is stronger isn’t it? Also, if we changed to Nickel plating, will the price reduce by a small amount?
Also, I noticed the Au plating will tarnish much more than.
The reason I don’t have the smallest magnets I order plated in Nickel is because they are not encased in plastic and I need a very inert material coating.
Is there a reason for this and would it help to have them double plated? Say nickel and gold?

Neodymium Permanent Magnets  Manufacturer China Rare Earth Magnet Limited:
Yes, Nickel plating is stronger than Ag plating.
The price of disc magnets with nickel plating is as follows:
Unit price: USD**/pc
Regarding Au plating, actually when you ordered Au plating, we have already double plated the magnets with Nickel + gold.
Just as when you ordered Nickel plating, all we use is Nickel + Cu+ Nickel 3 layers coating.
And please note that in terms of anti-corrosion/oxidation capability, Nickel is much better than Au.
Au coating is just better looking.

Need Nickel + Au Plating Neodymium Magnets:
Please change the magnets to Nickel plating.
The smaller magnets I do not encase in plastic and will need to be finished in Au, but having the double plating with Nickel and Au is what I need.
