Magnetic oil drain plug.

I would like to get a magnetic drain plug for my 919. I've read a few posts about these and it seems that magnets are denatured by heat. Few magnetic plug suppliers that I have looked at (ebay) explain what type of magnet is used.
My questions are, will they all work regardless of magnet type? Also would it be better to get a drain plug made from steel? I see some are aluminum.
Thanks.

This needs a full technical paper to properly answer.
Here's a brutally short story.
Magnets exposed to temperatures up to their Normal Operating Temp Limit are not affected by the heat.
Magnets exposed to a temperature beyond the Normal Limit, but below the Curie Limit, will lose strength, recover some of it after cooling, but experience a permanent loss of strength.
Magnets exposed to their Curie (temperature) Limit or above, lose 100 % of their strength, have zero recover after cooling, so in other words, are totally ruined.

In terms of a 919 magnetic trap, the rare earth magnetic material Neodymium would be fine for a magnetic trap bathed in sump oil, as long as the oil temp doesn't exceed 250 F or so.
Of course, if your 919 had an oil temp at the trap of 250 F, the magnet is the last thing to be concerned about !

Personally, if I was looking at magnetic trap drain bolts, I'd want a magnet type that would not lose any strength due to temperature range it was intended to be exposed to.

I just googled "magnetic drain plug" and it seems there are ones that are designed specifically for what you are asking. Whether or not they actually work, I wouldn't know.

Thanks for the advice. Ended up getting a Dimple magnetic plug. American made, with a high temp magnet. They have a good website, turns out they make hydraulic sump plugs for a Howitzer cannon.

Happy ending, and it's a co-opted artillery part no less ! LoL
