Does anyone know what magnetron magnets are made of and do they have any value?
Are you talking about MicroWave Magnetron?
Yes, I part out a dozen or so of them a week for the transformers.
I don't do many micro breakdowns, but when I do I try to keep the magnets whole, and use them to test magnetism. Their really strong for their size, and easy to handle. I keep one in my car, one in my toolbox, one on my toolbox, and their scattered all around my garage. I have a habit of losing magnets so it's nice to have them around.
If they break I throw them in the shred. Easy enough for me.
Magnets are usually made from AlNiCo - a mix of Aluminium, Nickel and Copper subjected to a very high electrical charge to polarise them. I've never scrapped them as they're exceptionally useful, but I'm willing to be they'd Ebay for more than they'd scrap.
i've never scrapped them either, at least not intentionally!! I have them all over my tool boxes and a bunch at my dads too. they come in handy for sooooo much stuff. I keep one on my vices to catch small pieces that might happen to fall that way, I keep them on my workbench to stick screws to I am going to use again for say a monitor and they are handy for sticking tools to all over the place when working on a mower or something outside or anywhere not near a work bench. but, I've also lost track of them and scrapped them when they were left stuck to something I planned on scrapping and off my truck bed too that way so good thing I have bunches of backups!
i keep them lined up in an aluminum baking pan, when its time to claen up after breaking things down i just drag the pan with magnets in it across the work area, all the base metal sticks to the ali pan then i hold the pan over my bucket of small items pick up the magnets from the pan and everything falls into the bucket, no having to pick the little small pieces off the magnets.
you can givr them to students who are doing windmill projects !!
Oh my gosh brandon I love that idea!!!
I HAD TO REPAIR MY WIFES CHLOTHES DRYER...well wouldnt you know it, i broke a internal clip that holds the 2 sections of steel together, so i just slapped one of the microwave magnets on it and it never moves... if you have enough of these magnets you may want to think about EBAY. i have a computer geek friend that buys magnets all of the time from ebay!
I have saved hundreds of them so far.
They chip easy & I don't think they are AlNiCo, simply because they don't have the chrome plating on them, could be wrong, dunno 100%.
I think Ebay could be a good way to sell them, some people don't really have a way to get a lot of them.
$2 a magnet & its getting close to what you make off the copper.
As they are so strong they get used in projects & stuff, making electricitys a good project.
The permanent magnets in the smartdrive motors can be replaced by the stronger magnets to make more power from the same parts.
Best 'Ferrous detector' ever. I have painted some & given them to the scrappers when I go to sell my metal, they love them.
Hello everyone. I'm new to the board and have gained so much useful information in the past month. In poking around I came across this post. Something to keep in mind when working with any strong magnets is to make sure that EVERYONE around you knows what you have in hand. The reason is that if someone with a pacemaker (like myself) gets close there could be some serious issues. Unfortunately I've been on the receiving end of a jolt and it's not fun.
As long as the magnet doesn't get closer than 4ft there shouldn't be any problems. Just my 2 cents.
