Common Questions About This Magnet
How does this magnet perform at high temperatures?
N50SH magnets retain most of their magnetic strength at elevated temperatures. Expect approximately 90% of room-temperature performance at 212°F (100°C) and approximately 80% at 300°F (150°C).
Is N50SH stronger than N42 or N45?
Yes. N50SH provides greater magnetic energy and holding force than N42 and N45 grades while also offering superior temperature resistance.
How should I mount this magnet?
For permanent installations, use industrial epoxy adhesives or mount the magnet within a recessed non-magnetic fixture. Avoid direct impacts, as neodymium magnets are brittle.
Can this magnet be used outdoors?
The Nickel-Copper-Nickel coating provides excellent corrosion resistance, but additional sealing is recommended for prolonged outdoor or marine exposure.
What direction is it magnetized?
This magnet is magnetized through the 1/4-inch thickness, with the north and south poles located on the 1" x 1" faces.
Do you offer wholesale pricing?
Yes. Contact Super Magnet Store for competitive volume pricing and wholesale discounts on high-temperature neodymium magnets.
Safety Notice
Neodymium magnets are extremely powerful and brittle. They can snap together unexpectedly, causing pinch injuries or chipping. High temperatures can increase stress on magnetic assemblies, so always handle with care. Keep away from children, pacemakers, magnetic storage devices, and sensitive electronics.
