N42 Neodymium Disc Magnet - 20mm dia x 5mm thick - 16.09lbs Pull

• Licensed Neodymium material.
• 37/47'' diameter x 1/17'' thick.
• +/-0.004" tolerance.
• Each magnet's north pole is on the non-adhesive face and the south pole is on the self-adhesive face.
• Convenient super-strong 3M 468 adhesive with easy-peel backing.
• Each magnet can support a steel weight of up to 16.09lbs vertically from the magnetic face when in flush contact with a mild steel surface.
• Excellent resistance to demagnetisation.
• Coated with three layers of nickel, copper and nickel to reduce corrosion and provide a smooth finish.

These thin but powerful licensed Neodymium self-adhesive magnets combine the performance of Neodymium with the convenience of self-adhesive making them ideal for creating fridge magnets, book and folder closures, packaging, retail displays and craft making. Remember, if using two together to attract you will need to make sure each has opposite poles on the non-adhesive side.

These high-performance Neodymium magnets utilise a firm acrylic pressure-sensitive adhesive that substantially increases in bond strength with natural aging. While the initial touch bond strength is enough to support the weight of the magnet, to ensure the adhesive can withstand the magnets pull strength we recommend allowing between 24 to 32 hours for the adhesive to fully cure.
