Standard Grades and Temperature Ratings:

N35 Magnets are rated maximum energy product of 35 MGOe with maximum operating temperature of 80°C. N35 magnets are easy to be used in general for their reasonable strength/cost ratio.

N38 Magnets are rated maximum energy product of 38 MGOe with maximum operating temperature of 80°C. N38 magnets have slight advantages over N35 and are features in applications where more strength is required.

N40 Magnets are rated maximum energy product of 40 MGOe with maximum operating temperature of 80°C. N40 magnets possess adequate Magnet grade strength in appropriate cost and applicable in various general and specific requirements.

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

N45 Magnets are rated maximum energy product of 45 MGOe with 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 product of 48 MGOe with 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 is the most powerful grade commercially available and is 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.
