Neodymium magnets

Nickel plate or zinc plate or black epoxy?

Does the nickel or zinc coating protect them from cracking better than the black epoxy?

No. I am sure that epoxy would absorb more energy than the thin coat of protective metal, even if it's the same thickness.

The coating isn't to protect them from breaking, its to protect them from the elements..

Well, if the nickle or zinc has any thickness at all, I think it would protect the magnet.
I have the expoxy coated ones, and they shatter if you drop them on the floor from 4 feet.

They'll shatter regardless.

It isn't for strength, it is for corrosion resistance.

 

dammit, i made it past the last magnet thread without buying a buttload of uberly powerful magnets...not sure if i can do it again

try to keep it non-geeky guys

Well, couldn't they just make the nickle plate slightly thicker and make the magnets strong enough to not shatter upon dropping?
Why do some use zinc and others use nickle?

I couldn't resist 🙁

Waiting for my package of fun to come 😀

Does Radio Shack sell these things? Just curious?

Also how do you pronouce these things?

Neo - like Matrix
dy - like die
mium - like 'me um'

neo die me um?

Is that right?

I imagine they could, but again.. the primary concern is corrosion resistance, not strength. They shouldn't ever be smacking against anything. Plus you have to also assume that a thicker coating would effect the magnets properties somewhat.

As for why some use nickel and some zinc.. just depends on the application. One is probably cheaper than the other, etc..

Just depends on the application considerations. Sometimes they're not coated at all, like in some HDDs.

Yes.

That's how I say it anyway, lol...

I wonder how much traffic we have generated for these places?

 

[screw3d]

Mine just came and HOLYSH1T these things are friggin' strong!! :Q😀

 

[Gurck]

Hrm, $30 for a box-o-fun eh? I might have to get in on this too...
