Permanent magnets are fragile. If slam together, magnets will peel, chip, crack or shatter. Eye protection should be used when handling magnets, since shattering magnets can launch small pieces at great speeds.
Neodymium magnets are easy to get rusty in the presence of moisture. Even with nickel-copper-nickel plating, magnets are not waterproof. If used in a moist environment, they can corrode and lose magnetic strength.
Powerful magnetic fields can interfere with compasses and navigation. Magnetic fields can influence compasses or magnetometers used in air transport, Smartphone and GPS devices. Hence, there are rules and regulations cover shipping magnets by air and ground delivery from IATA (International Air Transport Association).
Permanent magnets will lose magnetic force at high temperatures. The operating temperature for normal grade is 80°C (175°F). However the actual maximum operating temperature of a magnet can vary depend on the material, grade, magnet shape and how it is used.
Neodymium magnet powder or dust is flammable. Therefore, you should avoid drilling or machining neodymium magnets.
- Magnetized products should be packed with lining and shielding
- Magnet has strong magnetic force. So we should store it in ventilated, dry and anti-corrosion places to avoid corrosion.
- Permanent magnets are powerful. We should use special package to isolate magnetic force and keep outer carton no magnetic force.
- It’s better to stock Magnetized products under room temperature.
- Move carefully with shake-proof, collision-proof and rain-proof.
