Magnet fell to pieces? 1

[mechGHO]

Hello all,

So I was investigation the use of a neodymium magnet with N52 strength to see if it fit my application. The magnet also came into contact with my steel alloy hex keys and broke apart when I try to remove the magnet off the hex key. I was wondering what happened to cause this destruction and what is a safe way to dispose or make use of the remaining pieces?

It looks like it was a thin wall casting.
Is that correct?
Did it take an impact?

It has a black nickel coating. See link for the exact specifications of the magnet.

As far as impact goes, there was some and I also recreated a situation where I was basically rubbing the magnet on the hex key and it eventually broke and another situation where I forced an impact, but it was still fine.

There are a lot of Junk magnets on the market unless purchased from a known reliable source.

Any impact can be too much. There are often very fine cracks in these just from the force of magnetization.
Chipping and flaking are very common. This looks like a marginal item, but not too unexpected, even from a good source.
Remember that they want to fly apart.
