High temperatures neodymium magnets. The new Neodymium grades N30AH, N33AH, N35AH and N38AH grades, are grades of high temperatures neodymium magnets. AH series neodymium offer an exciting new choice with a working temperature up to 240˚ (while the EH series has a working temperature of 200°). Those grades are quite new and available for
Permanent losses: Above temperatures where the magnet material was originally sintered, structural changes will occur to permanently demagnetize a magnet. No amount of externally applied magnetic field will bring the magnet's strength back. For neodymium magnets, this temperature is very high, typically above 900°C to 1000°C.
Many applications, particularly within the manufacturing and engineering industries require magnets to be able to maintain their performance at incredibly high temperatures. Here you will find a selection of ferrite, alnico, samarium cobalt and special high-temperature neodymium grade magnets that all have high maximum operating temperatures.
Neodymium magnets operate best at lower temperatures, they even get stronger as the temperature gets colder, to a point of approximately -130°C. However, some grades of neodymium magnets can also be exposed to very high temperatures before their properties begin to change and they lose their magnetism, either temporarily or permanently.
This powerful neodymium block magnet measures 2" in length, 3/8" in width, and 3/8" in thickness and is made of a grade N42H high-temp neodymium, iron, and boron magnetic alloy blend and is rated for use in temperatures up to 212 F. This magnetic blend is patent licensed and made under the ISO 9001 quality control systems and is plated in zinc for a corrosion resistant finish. This magnet is
Neodymium magnets, also referred to as neodymium-iron-boron (NdFeB) magnets, have the highest magnetic field strength, but are inferior to samarium cobalt in resistance to oxidation and temperature. This type of magnet has traditionally been expensive, due to both the cost of raw materials and licensing of the patents involved. This high cost limited their use to applications where such high
Temperature Ratings Temperature Effects on Neodymium Iron Boron, NdFeB, magnets. The NdFeB magnets are the strongest magnets available. Up to +150 degrees C, they are stronger than the other Rare Earth magnet, SmCo. At around +150 degrees C and above these Neo magnets perform not as strongly as SmCo. The maximum recommended temperature for the
High-Temperature Resistance Magnets. Different properties of high-temperature magnets have different composition characteristics, and the magnitude of the magnetic force is also different. Generally, high-temperature resistance magnets can be divided into four categories according to their different types: 1. Neodymium High-Temperature Magnet
Neodymium-iron-boron magnets have high coercivity at room temperature but as the temperature rises above 100 °C (212 °F), the coercivity decreases drastically until the Curie temperature (around 320 °C or 608 °F). This fall in coercivity limits the efficiency of the magnet under high-temperature conditions such as in windmills, hybrid motors, etc. Dysprosium (Dy) or terbium (Tb) is added
Neodymium magnets will likely lose less than approximately 1% of their flux density over a 10-year period if their physical properties remain intact, and they are not subjected to demagnetizing influences (such as high-temperatures, opposing magnetic fields, radiation etc.).
High Temperatures Neodymium Magnets. The Neodymium grades N30AH and N33AH grades with a working temperature up to 240 ˚. These grades could be used instead or replace the more expensive samarium cobalt (SmCo 5 series). N55 & N52 Grade Neodymium Magnets Strong magnets, N55 and N52 grade neodymium magnets are the choice of many designers. Due to their high flux or holding
Neodymium magnets of the type N lose part of their magnetisation permanently at a temperature of 80 °C, tapes and sheets at 85 °C, ferrite magnets only at 250 °C. A vigorous cool-down (e.g. in liquid nitrogen) does not harm neodymium magnets, but ferrite magnets lose part of their magnetisation at a temperature of below -40 °C; magnetic tapes and sheets already below -20°C.
Alnico magnets are ideal for high heat applications due to the unique crystalline bonding between aluminum, nickel, and cobalt and the length to diameter ratios achieved during manufacture. Manufactured using casting and sintering, Alnico magnets are primarily comprised of the following family of material grades: alnico 2, alnico 5-7, alnico 8, and alnico 5.
JBF National's high temperature neodymium magnets are made from the highest quality rare earth neodymium, and rated at a 300 degree operating temperature. To ensure longevity and maximum protection from corrosion, these magnets come triple coated with a base and top finish layer of nickel, with a layer of copper in-between.
