Rare Earth Neodymium Magnets (6mm x 1.5mm)

Hopefully, everyone here knows what these are and what they are used for. I picked up a 100 on eBay because I didn’t want to wait the 2 to 4 weeks shipping times for the cheaper China-sourced magnets.

For those of you who are in a similar boat (you want the magnets now, not four weeks from now), I’m offering up the following:

10 individual magnets (6mm x 1.5mm) for $1.50

or

20 individual magnets (6mm x 1.5mm) for $2.30

Prices include first class shipping within the U.S.

Shipping international extra.

Post your interest here and I will PM you with the order information.

I figure on selling 7 packages of 10 magnets, maybe 8 packages if the demand is high.

I’ll take 10 magnets which for me should be a lifetime supply.

Who knows what these magnets will try to stick to on there way here. :bigsmile:

1dash1 confirmed my purchase and said he had a hard time getting it to go down the mail shoot without sticking to the side. Hilarious! :bigsmile:

16

Thanks for sharing the bounty! I need brass driver disk’s, maybe I can get a bunch and split them up!

Yep, it’s true. Took me two tries to get the envelopes down the Main Post Office’s mail (steel) chute without sticking.

I thought I did a good job of framing them in a cardboard card, so that the envelope would be nice and flat for processing.

What I didn’t count on was that by doing so, the flat side (the side that has the greatest magnetic pull) of all ten magnets would be exposed.

I’ve got one order of 20 to mail out this afternoon. I’m going to have to re-package it. I don’t think 20 exposed faces will make it through the USPS system. It will get stuck on a piece of metal somewhere. :Sp

Here’s what I was originally going to ship, cardboard flat with cutouts for 20 magnets, slid into a plain envelope. Notice the exposed faces.

And here’s the revised packaging. Only the edges of the two ends now present a strong magnetic force. And I covered both sides with bubble wrap before sticking it into the envelope, to smooth out the hump in the middle. Probably 50 times less magnetic force, now!

EDIT: Note magnets are symmetrically embedded into the cardboard such that half is sticking out on each side. With the bubble wrap, the finished surface is virtually smooth.

I’m looking for magnets with an OD that will fit snugly into a nylon or plastic washer, and be slightly thicker than the washer.

So far I’ve found some nylon washers with 8mm ID and 1.5mm thickness, and some magnets with 8mm OD and 2mm thickness — waiting to get them to see if they really fit together.

(This is because I don’t want any risk of having a magnet slip sideways and short circuit)

EDIT — that worked fine, with a little “3M Super Strength Adhesive” — it’s only barely sticky on nylon and chrome, but good enough.
Magnets are from “Super Magnet Man”

Wow that looks like a lot of work to send me these little buggers. If they hitchhike somewhere no big deal.
