Neodymium Magnet Grades

Standard Grades and Temperature Ratings:

N35 Magnets are rated maximum energy products of 35 MGOe with a maximum operating temperature of 80°C. They are generally easy to use because of their reasonable strength/cost ratio.

N38 Magnets are rated maximum energy products of 38 MGOe and have a maximum operating temperature of 80°C. They have slight advantages over N35 and are used in applications where more strength is required.

N40 Magnets are rated maximum energy products of 40 MGOe with a maximum operating temperature of 80°C. N40 magnets possess adequate Magnet grade strength at an appropriate cost and apply to various general and specific requirements.

N42 Magnets are rated maximum energy products of 42 MGOe with a maximum operating temperature of 80°C. N42 magnet is the basic general-purpose grade providing excellent magnetic performance at an acceptable cost.

N45 Magnets are rated maximum energy product of 45 MGOe with a maximum operating temperature of 80°C. N45 magnets are the replacements for N42 in applications that demand higher magnetic intensity.

N48 Magnets are rated maximum energy products of 48 MGOe with a maximum operating temperature of 80°C. N48 magnet is a high-performance grade it is mostly deployed in high-end applications.

N50 Magnets The maximum energy product is 50 MGOe and its maximum operating temperature is 80°C. N50 magnets are great in strength, hence suitable for tough uses.

N52 Magnets the maximum energy product is 52 MGOe and its maximum operating temperature is 80°C. The N52 magnets are the most powerful grade commercially available and are applied in the most severe conditions.

High-Temperature Grades:

Neodymium magnets can lose their magnetism at higher temperatures, so special high-temperature grades have been developed. These grades are denoted by a suffix indicating their maximum operating temperature.

• N42M - has a maximum operating temperature of 100°C.
• N42H have a maximum operating temperature of 120°C.
• N42SH have a maximum operating temperature of 150°C.
• N35UH have a maximum operating temperature of 180°C.
• N35EH have a maximum operating temperature of 200°C.
• N35VH have a maximum operating temperature of 230°C.

Information on Grades:

The temperature suffixes M, H, SH, UH, EH, and VH indicate the maximum operating temperatures of the magnets.

• M (Moderate Temperature) magnets can withstand up to 100°C and are suitable for slightly elevated temperature environments.
• H (High Temperature) magnets can withstand up to 120°C and are used in applications with higher thermal requirements.
• SH (Super High Temperature) magnets can withstand up to 150°C and are ideal for environments with significant temperature variations.
• UH (Ultra High Temperature) magnets can withstand up to 180°C and are designed for high-temperature industrial applications.
• EH (Extra High Temperature) magnets can withstand up to 200°C and are used in very high-temperature settings.
• VH (Very High Temperature) magnets can withstand up to 230°C and are suitable for extreme temperature conditions.
