Removing the coating on magnetic copper wire


Recommended Posts

Has anyone had any experience removing the clear coating that is used on copper wire used in relay coils and or transformers or electric motors?

 

I would like to do this without using any abrasives and also the wire I am hoping to do this with is .005" or 36 gauge.

Michael,

 

I believe they still use lacquer on those, Michael.   Is there a manufacturer's name available to you and/or the part number?  Might be able to get a spec sheet off the web.

Hi Mark,

This is what I have, it is old and I have no idea where I got it. I do know that i have had it for at least 40 years.

I would try soaking it in lacquer thinner and then clean with fine steelwool.  If this does not do the job repeat with acetone.

Even easier... look for larger stranded wire made up of fine uncoated strands. Done.

 

But not quite... straighten the wire: clamp one end in vise, and firmly pull the wire until you feel it yield just a bit... let loose, and the wire will be straight!

Before you get into things like lacquer thinner and paint strippers, try denatured alcohol. Back in the day, I believe a lot of that sort of coil wire was insulated with a coating of shellac and the color of the wire suggests this. If it's shellac, you're in luck. Just soak to soften and wipe off with a rag soaked in alcohol.

Take it from an old armature winder, burn it off.

On small wires like that a simple cigarette lighter will do the job nicely.
