It is a measure of the maximum energy product (BHmax), which is the point of highest magnetic strength on a magnet&#8217;s <a class=\"wpil_keyword_link\" href=\"https:\/\/osencmag.com\/blog\/demagnetization-factors-and-how-to-avoid-it\/\" target=\"_blank\"  rel=\"noopener\" title=\"demagnetization\" data-wpil-keyword-link=\"linked\"  data-wpil-monitor-id=\"873\">demagnetization<\/a> curve, expressed in MGOe (Mega Gauss Oersteds). Simply put, the higher the number in the magnet grade, the stronger the magnet.<\/span><\/p><p><span style=\"font-weight: 400;\">For example, a magnet grade like N52 refers to a Neodymium magnet with a maximum energy product of 52 MGOe, making it one of the strongest types of permanent magnets available. On the other hand, an N35 magnet would be relatively weaker.<\/span><\/p><p><span style=\"font-weight: 400;\">Magnet grades often consist of a letter followed by a number:<\/span><\/p><ul><li style=\"font-weight: 400;\" aria-level=\"1\"><b>N<\/b><span style=\"font-weight: 400;\"> stands for Neodymium (a type of strong rare-earth magnet).<\/span><\/li><li style=\"font-weight: 400;\" aria-level=\"1\"><b>C<\/b><span style=\"font-weight: 400;\"> denotes Ceramic.<\/span><\/li><li style=\"font-weight: 400;\" aria-level=\"1\"><b>SmCo<\/b><span style=\"font-weight: 400;\"> represents Samarium Cobalt.<\/span><\/li><\/ul><p><span style=\"font-weight: 400;\">The number represents the magnet&#8217;s strength (measured in MGOe). Higher numbers indicate stronger magnets. The most common grades of Neodymium magnets are N35, N38, N40, N42, N45, N48, N50, N52, and N55.<\/span><span style=\"font-weight: 400;\"><br \/><\/span><span style=\"font-weight: 400;\">The letter S or SH in a grade like N42-SH provides additional details regarding the magnet&#8217;s temperature resistance, indicating how well the magnet can withstand heat before it begins to lose its magnetism. For instance, N42 refers to a magnet with a maximum energy product of 42 MGOe, while SH signifies its ability to withstand higher temperatures.<\/span><\/p><p><span style=\"font-weight: 400;\">Taking Samarium Cobalt (SmCo) magnets as an example again, the BHmax range is from 16 MGOe to 32 MGOe. Its grade writing format is the same as neodymium magnets, and the higher the number after &#8220;SmCo&#8221;, the stronger the magnetic force. Common grades of samarium cobalt magnets are SmCo16, 18, 20, 22, 24, 26, 28, 30 and 32. As you can see, neodymium magnets have a higher MGOe value than samarium cobalt magnets, which indicates that the maximum magnetic energy product of neodymium magnets is stronger than that of samarium cobalt magnets.<\/span><\/p><p><span style=\"font-weight: 400;\">Different <a class=\"wpil_keyword_link\" title=\"types of magnets\" href=\"https:\/\/osencmag.com\/blog\/between-different-types-of-magnets\/\" target=\"_blank\" rel=\"noopener\" data-wpil-keyword-link=\"linked\" data-wpil-monitor-id=\"585\">types of magnets<\/a>, such as Neodymium, Samarium Cobalt, Alnico, and Ferrite, have varying strength ranges, with Neodymium being the strongest, followed by Samarium Cobalt, Alnico, and Ferrite.

For most grades:<br \/>Br Coefficient (a): ~-0.12%\/\u00b0C<br \/>Hci Coefficient (b): ~-0.6%\/\u00b0C<br \/>For example, a rise of 20\u00b0C above ambient (~25\u00b0C) in an N42 magnet may result in a 2.4% drop in magnetic output due to reversible losses. This loss is recovered when the temperature returns to ambient.<\/li><li><strong>Irreversible Loss:<br \/><\/strong>If the temperature exceeds the magnet\u2019s maximum operating range, an irreversible but recoverable loss may occur, where the magnet&#8217;s output does not fully return after cooling. This is due to partial demagnetization. In such cases, re-magnetization may be possible, but the magnet will demagnetize again if used in the same conditions.<\/li><li><strong>Low-Temperature Effects:<\/strong><br \/>NdFeB magnets can also operate at extremely low temperatures, but at ~135 Kelvin (-138\u00b0C), a phenomenon known as spin reorientation occurs, where magnetization shifts from an &#8220;easy-axis&#8221; to an &#8220;easy-cone.&#8221; This can cause a drop in output of up to 15%.

This is defined in units of Mega-Gauss-Oersteds, or MGOe. On the magnetic demagnetization curve, this is the highest point of magnet strength.<br \/>The intrinsic coercivity is the &#8220;Hci&#8221; of the material. When you look at the magnet chart for available materials, some grades will have different letters after them. These letters represent the magnet&#8217;s ability to resist demagnetizing forces, which may be temperature or other opposing magnetic forces acting on the magnet. There are several ways in which manufacturers or suppliers define coercivity in the world of permanent magnets, but <a class=\"wpil_keyword_link\" href=\"https:\/\/osencmag.com\/why-choose-osencmag\/\" target=\"_blank\"  rel=\"noopener\" title=\"we\" data-wpil-keyword-link=\"linked\"  data-wpil-monitor-id=\"597\">we<\/a> will focus on the most widely used one, the alphabetic system. This lettering system uses the following letters after the grade to define magnet specifications for resistance to demagnetizing forces: M, H, SH, UH, EH and AH. Yes, that&#8217;s right. This is the letter system that represents the temperature resistance grade of neodymium magnets. For ease of understanding, we will use ambient heat as the demagnetization force because it is the most common force that affects magnets. When a letter is used after a neodymium magnet grade, it indicates that that particular material has a greater ability to resist demagnetizing forces.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-0752349 elementor-widget elementor-widget-heading\" data-id=\"0752349\" data-element_type=\"widget\" data-e-type=\"widget\" id=\"Table\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">High-Temperature Neodymium Magnet Specifications Table.<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-d556d52 elementor-widget elementor-widget-text-editor\" data-id=\"d556d52\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p>The standard conventional neodymium magnet grades have been sorted out above and will not be repeated here.

mechanical properties of neodymium magnets determine their excellent strength and magnetic properties. These magnets have a rare earth density of approximately 7.4\u20137.5 g\/cm\u00b3, making them relatively compact but very powerful.<br \/>Their mechanical strength also deserves special praise &#8211; a compressive strength of up to 950 MPa (137,800 psi), while a tensile strength of about 80 MPa (11,600 psi) and a Vickers hardness (Hv) between 560 and 600.<br \/>The durability and resistance to external forces of the magnet block are ensured.<br \/>In terms of thermal properties, neodymium magnets exhibit anisotropic behavior. The coefficient of thermal expansion along the magnetization direction is 5.2 \u00d7 10\u207b\u2076 \/\u00b0C, while the coefficient of thermal expansion in the perpendicular direction is -0.8 \u00d7 10\u207b\u2076 \/\u00b0C, meaning that temperature fluctuations have different effects on dimensional stability depending on the orientation. The Curie temperature range is 310\u00b0C to 330\u00b0C, and the thermal conductivity of 7.7 kcal\/(m\u00b7h\u00b7\u00b0C) plays a role in heat dissipation, a factor to consider in high-power applications. .<br \/>Typical electrical resistivity measurements for neodymium magnets are 150\u2013160 \u00b5\u03a9\u00b7cm, which, while relatively high for metals, is still lower than that of insulating materials. This makes NdFeB magnets susceptible to eddy currents in AC applications.<\/p><table><tbody><tr><td><p><b>Property<\/b><\/p><\/td><td><p><b>Symbol<\/b><\/p><\/td><td><p><b>Unit<\/b><\/p><\/td><td><p><b>Value<\/b><\/p><\/td><\/tr><tr><td><p><b>Density<\/b><\/p><\/td><td><p><span style=\"font-weight: 400;\">D<\/span><\/p><\/td><td><p><span style=\"font-weight: 400;\">g\/cm\u00b3<\/span><\/p><\/td><td><p><span style=\"font-weight: 400;\">7.4 \u2013 7.5<\/span><\/p><\/td><\/tr><tr><td><p><b>Compression Strength<\/b><\/p><\/td><td><p><span style=\"font-weight: 400;\">C.S<\/span><\/p><\/td><td><p><span style=\"font-weight: 400;\">MPa (psi)<\/span><\/p><\/td><td><p><span style=\"font-weight: 400;\">950 (137,800)<\/span><\/p><\/td><\/tr><tr><td><p><b>Tensile Strength<\/b><\/p><\/td><td><p><span style=\"font-weight: 400;\">\u03c3UTS<\/span><\/p><\/td><td><p><span style=\"font-weight: 400;\">MPa (psi)<\/span><\/p><\/td><td><p><span style=\"font-weight: 400;\">80 (11,600)<\/span><\/p><\/td><\/tr><tr><td><p><b>Vickers Hardness<\/b><\/p><\/td><td><p><span style=\"font-weight: 400;\">Hv<\/span><\/p><\/td><td><p><span style=\"font-weight: 400;\">D.P.N<\/span><\/p><\/td><td><p><span style=\"font-weight: 400;\">560 \u2013 600<\/span><\/p><\/td><\/tr><tr><td><p><b>Young\u2019s Modulus<\/b><\/p><\/td><td><p><span style=\"font-weight: 400;\">E<\/span><\/p><\/td><td><p><span style=\"font-weight: 400;\">GPa (ksi)<\/span><\/p><\/td><td><p><span style=\"font-weight: 400;\">160 (23,200)<\/span><\/p><\/td><\/tr><tr><td><p><b>Poisson\u2019s Ratio<\/b><\/p><\/td><td><p><span style=\"font-weight: 400;\">\u03bd<\/span><\/p><\/td><td><p><span style=\"font-weight: 400;\">\u2014<\/span><\/p><\/td><td><p><span style=\"font-weight: 400;\">0.24<\/span><\/p><\/td><\/tr><tr><td><p><b>Electrical Resistivity<\/b><\/p><\/td><td><p><span style=\"font-weight: 400;\">\u03c1<\/span><\/p><\/td><td><p><span style=\"font-weight: 400;\">\u00b5\u03a9\u00b7cm<\/span><\/p><\/td><td><p><span style=\"font-weight: 400;\">150 \u2013 160<\/span><\/p><\/td><\/tr><tr><td><p><b>Thermal Conductivity<\/b><\/p><\/td><td><p><span style=\"font-weight: 400;\">k<\/span><\/p><\/td><td><p><span style=\"font-weight: 400;\">kcal\/(m\u00b7h\u00b7\u00b0C)<\/span><\/p><\/td><td><p><span style=\"font-weight: 400;\">7.7<\/span><\/p><\/td><\/tr><tr><td><p><b>Specific Heat Capacity<\/b><\/p><\/td><td><p><span style=\"font-weight: 400;\">c<\/span><\/p><\/td><td><p><span style=\"font-weight: 400;\">J\/(kg\u00b7\u00b0C)<\/span><\/p><\/td><td><p><span style=\"font-weight: 400;\">350 \u2013 500<\/span><\/p><\/td><\/tr><tr><td><p><b>Thermal Expansion Coefficient<\/b><span style=\"font-weight: 400;\"> (Parallel)<\/span><\/p><\/td><td><p><span style=\"font-weight: 400;\">C\/\/<\/span><\/p><\/td><td><p><span style=\"font-weight: 400;\">10\u207b\u2076\/\u00b0C<\/span><\/p><\/td><td><p><span style=\"font-weight: 400;\">5.2<\/span><\/p><\/td><\/tr><tr><td><p><b>Thermal Expansion Coefficient<\/b><span style=\"font-weight: 400;\"> (Perpendicular)<\/span><\/p><\/td><td><p><span style=\"font-weight: 400;\">C\u22a5<\/span><\/p><\/td><td><p><span style=\"font-weight: 400;\">10\u207b\u2076\/\u00b0C<\/span><\/p><\/td><td><p><span style=\"font-weight: 400;\">-0.8<\/span><\/p><\/td><\/tr><tr><td><p><b>Curie Temperature<\/b><\/p><\/td><td><p><span style=\"font-weight: 400;\">Tc<\/span><\/p><\/td><td><p><span style=\"font-weight: 400;\">\u00b0C<\/span><\/p><\/td><td><p><span style=\"font-weight: 400;\">310 \u2013 330<\/span><\/p><\/td><\/tr><\/tbody><\/table>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-4b4565a elementor-widget elementor-widget-heading\" data-id=\"4b4565a\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h3 class=\"elementor-heading-title elementor-size-default\">3 Common Neodymium Magnet Measurement Systems.<\/h3>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-3bedbc3 elementor-widget elementor-widget-text-editor\" data-id=\"3bedbc3\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p>When measuring the performance of magnets, three main measurement systems are commonly used: the CGS (centimeter-gram-second) system, the SI (International System of Units), and the English system.
