Q:Can these Neodymium magnets stick adhere to aluminum metal. like windows?
by|May 28, 2022
3 Answers
Answer This Question

A:  No, unfortunately aluminum isn't magnetic.

    A:  No. They don't have any adhesive on them, and aluminum isn't magnetic. Only things like steel and iron (and not all of these - some stainless steel isn't magnetic). Depending on what you're trying to do, it might be possible to use something like epoxy or silicone adhesive to attach them to the window frame and then hang something from them.

      A:  The 3/8 in. Neodymium Rare-Earth Magnet Discs (12 per Pack) will not adhere to aluminum as aluminum is not magnetic.

        Q:Is the hole beveled or counter-sunk? How do I screw on the magnet and not have the screw head interfere with the magnet face? If not beveled, even a flat-head screw will interfere. Thank you.

        A:  It flat like a regular flat washer. And yes you can put a screw on the middle provided it is smaller in diameter

        A:  The hole is not counter-sunk for Master Magnet 3/8 in. Neodymium Rare-Earth Magnet Discs (12 per Pack). If using with a screw, the screw head will interfere with the magnet surface.

          Q:Will these withstand temperature up to 500 Fahrenheit?
          by|Jan 14, 2022

          Answer This Question

          A:  not sure these would melt but it i believe they will permanently loose their magnetism. heat resistant examples can be found for big $$$.

          by|Jan 31, 2022

            A:  We would not recommend these magnets for uses at high temperature such as at 500 Fahrenheit. While Neodymium does withstand heat better than most magnets, it will start to demagnetize at about 170 to 180 Fahrenheit.

                I had a magnetic drape rod that kept falling off, even when i tried gluing it on. but i took off the rod, put a wire through the drape, and through the magnet, now the curtain holds up on its own. the sun is blocked and when i want to look out, i can slide the magnets aside. you will find so many great uses for these! I keep buying more. see my photo.
