Material: Néodyme Magnets
Certification:RoHS passed
Magnetization: through thickness 3mm direction/ poles on largest surfaces
Max Operating Temperature: 80°C/176°F
Plating: nickel copper nickel triple layer plated
Features: Super strong rare earth neodymium magnets -they are hard to separate once they get attracted with each other. It's perfect for wind generators, DIY projects, science projects etc.
Caution: strong magnets are brittle; strong magnet could pinch your fingers badly; if you allow two magnets attract together, it may cracks and the chips could hurt your eyes.
Never place neodymium magnets near electronics, such us floppy disks, credit cards, magnetic I.D. cards, cassette tapes, video tapes, TV, VCRs, CRT displays.
Neodymium magnets are brittle, and can peel, crack or shatter if allowed to attract together.They also do not take kindly to machining.
Most neodymium magnets will lose their magnetic properties if heated above 80°C/176°F .
