I need to glue a small circular magnet to a steel plate. It doesn't have to be rock solid, but I'd like it to stay. What kind should I use? I searched around a bit and found that JB Weld works for steel on steel, should I use that?

JB Weld is what I have used with great success!

FWIW

I just used a product called "Power Poxy" to glue a magnet to aluminum yesterday. It seems to work well, but I haven't really put it to the test yet.

I bought it at Wal Mart and is supposed to be 4 times stronger than super glue. It is ultra-clear, will not yellow, and it works on all types of metal. It will hold in about I minute, cures to be handled lightly in about an hour. Full cure for maximum strength is 24 hours.

If it works as advertised it should be good stuff!

I would think that any 2 part epoxy would work - I have had good luck with this for all the tasks I've used it for. I have not had very good luck with super glue and metal, as any impact tends to dislodge it, but it depends on the exact situation.

PC7 is a two part epoxy that I have found superior to most anything else. I find it at Ace Hardware.

A buddy of mine patched a hole in his engine block by using JB Weld and a quarter! He blobbed on the JB Weld, pushed the quarter into it over the hole, frosted on some more JB Weld and let it cure. It held just fine and lasted longer than that engine.

Guerilla glue will glue anything to anything if you can clamp it.... It's unhealthy stuff to use- but it holds.

I have been using 2 part epoxy recently to glue magnets to magnets and magnets to wood. It is available at Wal Mart in different formulas. The real quick drying kind was too quick drying for me. I would rather have a little more time for it to take a set. It seemed to heat up and expand too much, before I had time to do anything with it. It messed me up once and I had to do a redo. I always let it dry 24 hours for full strength anyway, so I went back to the slower drying type and it worked better for my project.

I find the two-part adhesives somewhat messy to work with and always wonder if I'm mixing the exactly right amounts of catalyst or hardener. I've got epoxy and JB Weld but seldom use them.
Many years ago I needed to glue sheet rubber to plastic and metal and a tech rep at the rubber supply company said to use an industrial adhesive called E6000. In those days it was hard to find but nowadays it is sold in silver tubes in many hardware stores. It is like thick, thick contact cement and complete hardening takes about 24 hours. Clean your metal with alcohol to remove oils before gluing.. good advice when using any type of glue on nonporous surfaces.

Hot Glue may work just fine! All the above suggestions are excellent!!

I don't know- honestly, you may not have a lot of luck using hot glue, especially if the object is going to be under any stress at all- metal's not porous enough for hot glue to be effective (or even white glue for that matter.) Stick with the two part epoxies and stuff like JB Weld for the strongest joins.

I spoke with a friend yesterday who did this with Gorilla Glue, and said it's held for a long time despite attempts to pull the pieces apart.

Look for a product called E6000. It comes in a tube, it make less mess than epoxy, and holds really well.

I think it would depend on the size and power of the magnet. Simple Elmers glue would work for some applications, gorilla glue will attach anything to anything. 2 Part epoxy works well for most surfaces as well. I use rare Earth magnets and I use all the above as well as 2 sided tape for the smaller magnets. Like I said, it depends on the size and power of the magnet as well as the types of surfaces you are joining.

I have used Gorilla Glue. You can use this on any thing.

As mentioned in the above posts, my suggestion would have been to use Gorilla Glue. It is a 100% Waterproof polyurethane glue that will bond Wood, Stone, Metal, Ceramics and just about anything else. Gorilla Glue is probably the strongest and most versatile glue on the market today.

Old post but Gorilla Glue works great. I glued a small Neodymium magnet to the door of my mailbox to keep is shut. Glue lasted about 10 years and that was exposed to Texas weather. One thing to keep in mind is that Gorilla Glue expands when it dries so be careful of how much you use.

You have to first sand the magnet with coarse sandpaper to bet a "bite" on it, the same as the area of steel it is to be attached to. A few dabs of Gorilla Glue will work great as well as J B Weld is good. Hot glue will not be permanent.

If you use Gorilla glue, you should clamp the two pieces together with a steel C-clamp. This glue tends to expand significantly. It will ooze out along the edge of the magnet, but you can remove the excess glue away easily with a chisel.

E6000 is what I use but do let it cure fully a week.
