Magnetic Sheet Material

Armstrong Magnetics.

There may be probably are others. This is one I am familiar with.

This is my supplier.

AFAIK it is extruded first, then magnetised later.

may be of help.

P.S. Keep it away from your credit cards, or yer'll be sorry!

This was discussed a while back. It's called a Halbach array.

Sorry, I messed up pasting the link.

The fridge magnetic tends to be .5mm maximum, the stuff for vehicle signs is .9/.85mm thick. It's native colour is brown/black, but it is usually faced with an adhesive vinyl. If you have a local signmaker he/she will have some.

It does not all have the same power of attraction. I have a roll here that won't even stay rolled up without tape on it, and a roll that you have to get your nails under to pull it open.

Although if yours was 1/8th it wasn't this stuff.

CJ,

Do you have any sourcing info or specifications on the stuff you describe as "a roll that you have to get your nails under to pull it open" ... this sounds like something I could use.

Kind regards ...

It's the product you have discounted, the ordinary vehicle magnetic sheet. It sounds like, as you say, the material you are looking for is in a different league. I have never seen any with the stripes on the back.

Thanks to all, so far, for their input, but so far, I haven't found what I am looking for.

The material I had seemed much more than just signage-type material, and definitely more than the run-of-the-mill 'refrigerator' magnet material. I have nothing to play with at the moment, but what I recall was something that had a remarkable strength.

I work in design and manufacturing, and often, we 'attach' things magnetically. Until several months ago, the system of choice was small Neodymium magnets ... anywhere from the size of a dime or smaller, to maybe the size of a nickel. But, the cost of Neo has skyrocketed to the point that a piece that used to cost $0.05 each, is now closer to $0.40 each. It doesn't sound like much of an increase, but in some designs I am using 6 or 8 pieces.

I really believe this material I reviewed several months ago could take the place of Neo slugs in some of these applications ... if only I could find the same or similar material.

Kind regards ...

Hi

I can't help but am fascinated by what you are looking for or seen in the past. I will just follow this thread for a while and see what comes up. I too have an application for such a material but it is not as urgent.

Good luck, Ky.
