Important product safety information relating to Rare Earth magnets.
Your Rare Earth magnet is the most advanced permanent magnet available. Due to its power and composition, special care must be taken to ensure appropriate safety when handling or storing these magnets.
Mechanical Shock:
Magnets are brittle and may damage easily.
WARNING – DO NOT:
…drop the magnet onto a hard surface.
…allow magnets to smash together in an uncontrolled fashion.
…allow the magnet to smash together with metal.
…strike with tools, or attempt to machine cut.
Temperature:
Maximum operating temperature of the magnets is between 80°C and 100°C. Exposure to temperatures above these maximum limits may lead to loss of magnetic coercivity.
Store and use magnets in a cool environment to prevent demagnetisation.
Moisture:
External nickel plating will combat corrosion of the magnet. For further protection, apply a protective coating of adhesive sealant or similar to all exposed areas.
Although plating discolouration may occur over time, this does not affect the quality of the magnet.
Demagnetisation:
Rare Earth magnets will gradually suffer diminished coercivity if subjected to repeated mechanical shock, or excess temperatures.
Your Rare Earth magnet is extremely powerful, and may demagnetise other types of magnets.
