12mm dia x 4mm thick N42 Neodymium Magnet - 3kg Pull

• 12mm diameter x 4mm thick
• +/-0.1mm tolerance
• Each magnet's north and south pole are on opposite 12mm diameter faces
• Each magnet can support a steel weight of up to 3kg vertically from the magnetic face when in flush contact with a mild steel surface of equal thickness
• Excellent resistance to demagnetisation
• Each magnet is coated with three layers of nickel, copper and nickel to improve corrosion resistance and provide a smooth and clean finish

These neodymium disc magnets may be small but they have an astonishing pull of 3kg. Each magnet is coated with three layers of nickel, copper and nickel to improve corrosion resistance and provide a smooth and clean finish. Our neodymium magnets have many creative uses including modelling and theatre design, furniture making, exhibitions, displays and packaging. They also have many uses in engineering and manufacturing where small size and maximum strength are required.
