Product Description

Disc magnets were ordered, ‘square’ magnets were delivered. Supplies are limited, but if enough interest is found, further orders will be considered.

Also, some disc magnets were ordered at double the intended thickness (See F, G). The 1″ disc magnets are very strong and should, under no circumstances, be handled by children.

Nickel Plating: The standard coating for neodymium magnets is nickel. A coating is necessary because the combination of metals that makes up Neodymium magnets corrodes quickly when exposed to air. Some of our magnets are triple coated with Nickel Copper Nickel (NiCuNi) for extra durability.

NdFeB: This specification describes the composition of the magnet, Neodymium-Iron-Boron, to differentiate between magnet types and facilitate further research if necessary.

Grade: The N rating of a magnet is the way those who deal with magnets on a regular basis denote the strength of a particular magnetic material regardless of its shape. The pull force takes into account the geometry of the magnet as well

Maximum Operating Temperature: NdFeB magnets begin to act unpredictably at temperatures above 80°C (176°F). They will lose their (permanent) magnetic properties at around 200°C.
