Bonding a Nickel Coated Magnet to Aluminum

Bonding a Nickel Coated Magnet to Aluminum

Bonding a Nickel Coated Magnet to Aluminum

(OP)
Hello Everyone,

I am bonding a higher strength neodymium magnet to an engine oil drain plug. The Magnet is Nickel plated and the plug is 6061-T6. It's an air cooled motor so the engine temp will see around 235-265F depending on conditions.

I would like to use a room cure adhesive for convenience but I think adhesives that cure at lower temperatures will not like the higher operating temperature. I was thinking I should pick a "Hi Temp" Epoxy and just get a cheap toaster-oven or something to try and cure the adhesive. I don't want something that cures at a super high temp because I want to anodize the plugs and I am afraid the higher temps might ruin the color of the anodizing. Also, I think going beyond 300 degrees (ish) will also ruin the magnet I purchased.

Thanks for any suggestions.

RE: Bonding a Nickel Coated Magnet to Aluminum

You still want to inset the magnet into a socket in the plug and stake it in place. This greatly reduces the possible stress that can be applied to the bond line and will retain the magnet even if the adhesive fails. Then why use adhesive? Peening is not 100% reliable either.
