cylinder neodymium magnet has low working temperature for heat applications, but higher levels of heat resistance materials are being introduced periodically.

product name:n52 neodymium block magnet with two countersunk
Material: neodymium, iron, boron and a few transition metals

Block Neodymium 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. Their maximum energy product can be 35MGOe~50MGOe , Block Neodymium magnets are marinly used for generator and other industrial application.
