1. Be careful fragile and clip hand.
2. Placed in a dry place, stored at room temperature!
3. When connecting two magnets, must be careful draw them,
close to each other slowly and gently. Hard crushing would cause damage and cracks in the magnetic material.

high temperature neodymium magnets are made from the highest quality rare earth neodymium, and rated at a 300 degree operating temperature. To ensure longevity and maximum protection from corrosion, these magnets come triple coated with a base and top finish layer of nickel, with a layer of copper in-between.

Neodymium permanent magnets (Nd-Fe-B) are composed of neodymium, iron, boron and a few transition metals. These magnets are extremely strong for their small size, metallic in appearance and found in simple shapes such as rings, blocks and discs. N33EH Heat Resistant Powerful Permanent Motor Magnet

Attributes of Neodymium
Very high resistance to demagnetization
High energy for size
Good in ambient temperature
Moderately priced
Material is corrosive and should be coated for long term maximum energy output
Low working temperature for heat applications, but higher levels of heat resistance materials are being introduced periodically.
