Sintered smco needn't to be coated because it is difficult to be eroded and oxidized. Features 1. Smco magnet, permanent magnet, rare earth magnet. 2. High working temperature. 3. Excellent resistance to corrosion, no coating is needed for the surface protecting. 4. Smco magnet is suitable for machines with high magnetic requirement and good for strict working environment requirement. 5. Common uses in different fields. Surface treatments The corrosion resistance of smco magnets is considered good. Although surface coating or plating is not generally required for smco magnets, all kinds of surface coating are also available, like nickel, zn, ni-cu-ni, gold, silver, sn, chrome, abs coating, rubber coating, ptfe(telfon) coating, stainless steel case, etc. Smco typical physical properties

Neodymium Magnets China Manufacturer Custom Neodymium Arc Shaped Magnets Arc magnets are mainly used in permanent magnet DC motors. Unlike electromagnetic motors that generate magnetic potential sources through excitation coils, PM motors use permanent magnet materials to generate constant magnetic potential sources. Instead of electric excitation, permanent arc magnets have many advantages, which can make the motor simple in structure, convenient in maintenance, light in weight, small in size, reliable in use, low in copper consumption, and low in energy consumption. Standard Neodymium Magnets Neodymium magnets (also known as Nd-Fe-B) is one type of rare-earth permanent magnet. And it is an important component for electric vehicles, house appliances, robots, garden tools, medical equipment, etc. AH Magnet is specialized in researching, developing, manufacturing and exporting high-performance sintered neodymium iron boron magnets, 47 grades of standard neodymium magnets, from N33 to 35AH, and GBD Series from 48SH to 45AH are available. All magnets are widely applied to electric motors such as servo motors, stepper motors, brushless motor, linear motors, permanent magnet synchronous motors, etc. Aim to increase the corrosion resistance of sintered neodymium iron boron magnets and to meet the designated surface requirements, we provide the normal coating layers, like nickel-coating, zinc-coating, epoxy-coating, aluminum-coating and passivation. We also customized composite coating to ensure durability of magnets according to different design and application environment of permanent magnets. Find the suitable NdFeB to meet your design requirements from the following sheet and download the related files. And FIVE important keys should be considered when you choose from these grades.

Product Description Compression bonded magnets are made by using many isotropic Neodymium, Iron, and Boron materials, as well as crushed & powdered Samarium and Cobalt ingredients. Combinations of different elemental grades are used to create specific magnetic properties. Compression bonded magnets offers higher magnetic strength than injection molded magnets due to their higher magnetic particle density, but is unfortunately limited to simple geometric shapes due to the compaction process. The epoxy used is very resistant to normal industrial solvent and automotive fluids.The normal applications of these magnets range from below -40 and beyond 165. Why choose Bonded NdFeB Magnet.? 1. High quantity and even volume manufacturing, with up to millions of pieces per year. 2. High accuracy in size. The bonded magnet may be formed into magnetic components of relatively complicated shapes. 3. Single-time molding and multi-poles orientation. 4. The injection molded magnet has a high mechanical strength and may be molded together with other matching parts. 5. Effective surface treatment to prevent corrosion. Good corrosion-resistance and nice surface: The product is coated with epoxy resin parylene-coating and the anti-corrosion is very good. The surface is smooth, clean and nice-looking. No bubble, no crack, no strip-off, and no chip. 6. Stable working temperature. The working temperature is high up to 150. 7. Excellent magnetic properties. The energy product is 3 times as large as anisotropic ferrite. The intrinsic coercive force is high. During the large-scale production, the magnetic properties are stable and the conformity is good. 8. Application to Bonded NdFeB. Widely applied in all kinds of mini-motors, auto motors, air-conditioner motors,automatic controlling devices, sensors,drivers,telecom and instrument industry.
