Magnetic Properties of Sintered NdFeB from Magengine

Product catalog summary

Overview: This document provides detailed specifications of various grades of sintered NdFeB magnets, focusing on their magnetic properties and physical characteristics. The data is presented for different grades, including N35, N38, N40, and others, with variations such as M, H, SH, UH, EH, and AH.

Key Sections:

Magnetic Properties: The document lists the remanence (Br), coercive force (bHc), intrinsic coercivity (iHc), and maximum energy product (BHmax) for each grade. These properties are crucial for determining the magnet's strength and stability under different conditions.
Physical Properties: Density and maximum working temperature are provided for each grade. The temperature coefficients of Br and iHc are also included, indicating how these properties change with temperature.
Curie Temperature: The Curie temperature is specified for each grade, which is the temperature above which the magnet loses its permanent magnetic properties.
Additional Information: The document notes that derivative grades with prefixes or suffixes may have improved properties. It also mentions that the maximum working temperature can vary based on the magnet's dimensions and environmental factors.

Summary of Data: The document includes a comprehensive table listing the specific values for each property across different grades. For example, the N35 grade has a density range of 11.8-12.3 g/cm³, a maximum working temperature of 80°C, and a Curie temperature of 320°C. The remanence for this grade is between 1.18-1.23 T, with a coercive force of ≥10.8 KOe.

Conclusion: This document serves as a technical reference for selecting the appropriate NdFeB magnet grade based on specific application requirements, considering factors like magnetic strength, temperature stability, and physical dimensions.
