Find Verified Customized Powerful Rare Earth Magnets Suppliers, Manufacturers and Wholesalers

Neodymium Magnets China Suppliers Neodymium Magnets China Factory Rare earth magnets are very strong magnets made from alloys of rare earth elements. They are the strongest among the permanent magnets made. These magnets can be manufactured through sintering, compression bonding, injection molding, and extrusion. Since their prices became competitive in the 1990s, rare earth magnets have been replacing Alnico and ferrite magnets in many applications in modern technology requiring powerful magnets. Their greater strength allows smaller and lighter magnets to be used for given applications that require high strength. The material is easily magnetized in one direction, but is able to prevent magnetic pull in any other direction. As a professional magnets manufacturer, AH Magnet is committed to supplying neo magnets with normal and complex shapes. The normal magnet shapes are ring, block, round, disc, are, horeshoe, cylinder, sphere, etc. And, the most suitable magnets should be prpduced according to customers designs, click to learn about custom rare earth magnets. PRODUCT DESCRIPTION Materials Rare earth permanent magnet, Ferrite, Samarium cobalt magnet About this Item Although NdFeB magnet is a kind of hard and brittle material, we can customize some complex shapes according to customers requirements. We have produced some complex shapes such as different heads, convex, concave, slotted, side punched, cut corners, non-semi-circular and countersunk magnet. Different fixtures are needed when make complex samples and mass production. However, we always waive the cost of fixtures once the minimum order are USD100. We do not set MOQ, maybe 1-5 pieces are also feasible, because the order amount is more calculated based on the magnetic properties and the difficulty of production. What are the Different Types Of Rare Earth Magnets? There are two types of rare earth magnets, Neodymium and Samarium-Cobalt. Their shapes can include arc, block, cube, cylinder, disc, rod, sphere and many more. You can browse through our current shapes and sizes to find the right magnet for your application. If you need a custom design, we can work with you to create unique specifications for all shapes and sizes. Contact AH Magnet, an industrial rare earth magnet manufacturer, to find out how we can help provide you custom rare earth magnets.

Some of the main difference between the two types of rare earth magnets are: Advantages of Each Type of Rare Earth Magnet Neodymium magnets have the highest energy product of any material, and this type of magnet is known for its ability to be created in a wide range of available shapes, sizes, and grades.

Size:6.35x38.1mm Grade:n52 Axially magnetized This cylinder magnet can be applied for magnetic sensors. Magnetic cylinder sensors are mainly used to monitor the piston position on cylinders and grippers. The field of the magnet integrated into the piston is detected by the sensor through the actuator wall. Thanks to the contact-free position detection method, magnetic cylinder sensors are reliable and wear-free: no loss of contact material, no impacts, no adhesion, and only one switching point. Moreover, this cylinder neo magnet can also be applied for magnetic stir bar. If you are looking for magnetic rod at this size, we won¡¡¥t charge any molding / tooling fees cuz we have had all these necessary molds. Both axially magnetized and diametrically magnetized magnets are available. Before mass production or purchase order placed, we will mail samples to our customer for their confirmation. Samples usually are free while customers have to pay for the freight. Usually for small order, our lead time is about 2 weeks. Fast delivery can be ensured. We have not received any complaint about the quality of our magnets such as magnetic property losing after a period of time or coating peeling and so on.. Packed in small box and then standard export cartons with magnetism shielding foil

Sintered NdFeB magnets are the most powerful commercialized permanent magnets available today, with maximum energy product ranging from 26 MGOe to 52 MGOe. Nd-Fe-B is the third generation of permanent magnet developed in the 1980s. It has a combination of very high remanence and coercivity, and comes with a wide range of grades, sizes and shapes. With its excellent magnetic characteristics, abundant raw material and relatively low prices, Nd-Fe-B offers more flexibility in designing of new or replace the traditional magnet materials such as ceramic, Alnico and Sm-Co to achieve high efficiency, low cost and more compact devices. Advantages *Extreme strong Br Resident induction. *Excellent demagnetization resistance capability. *Good Price relative to its high magnetic properties. Magnetic characteristics of sintered NdFeb Note:The above mentioned data is given at room temperature. The above-mentioned maximum working temperature of magnet is changeable due to the ratio length and diameter,surface coating and environmental factors. FAQ 1. MOQ: less quantity is acceptable for your easy start of business 2. Sample lead time: 15-20 days. 3. Port: Shanghai, Ningbo, China any port. 4. Fast Delivery: when you choose the item and decide your design, we can produce it as fast as possible. 5. If you would like to make an enquiry, how can you contact us? 6. The way of identify the pole of magnet: The easiest way is to make a dot on the North or South or both Poles. If you need, we can make the dot as your requirement 7.Is one pole stronger than the other? No, both poles are equally strong 8.Which is the strongest type of magnet? Neodymium (more precisely Neodymium-Iron-Boron) magnets are the strongest permanent magnets in the world. 9.Can you supply BH Curves, or Demagnetization Curves for your magnets? Yes, we've offered Demagnetization Curves for our most common Neodymium magnet grades right here. 10.Will my neodymium magnets lose strength over time? Very little. Neodymium magnets are the strongest and most permanent magnets known to man. If they are not overheated or physically damaged, neodymium magnets will lose less than 1% of their strength over 10 years - not enough for you to notice unless you have very sensitive measuring equipment. They won't even lose their strength if they are held in repelling or attracting positions with other magnets over long periods of time. carton

Rare earth samarium cobalt magnets, shorted as SmCo rectangular magnet, are a type of powerful permanent magnet made from the basic elements samarium and cobalt and other metal rare earth materials by mixing, melting, grinding, pressing and sintering. They come in various sizes and shapes, like disc,bar, ring, arc,block, etc.,. Similar to neodymium strong magnets, they belong to the rare earth magnet category, and tcan be classified as SmCo5 and Sm2Co17 according the composition ratios of samarium and cobalt. In comparison to neodymium rare earth magnets, although samarium cobalt magnets may not have as strong magnetic force, they possess two distinct advantages. Firstly, they operate effectively within a higher temperature range, and secondly, they exhibit greater resistance to corrosion. Due to these characteristics, large smco block magnets are commonly employed in applications that demand high operating temperatures, such as generators, pump couplings, sensors, electric motors, marine applications, as well as in the automotive, racing, aerospace, military, and food and manufacturing industries. SmCo rare earth magnets not only perform well at high temperatures but also maintain their magnetic properties even in temperatures below absolute zero (-273 degrees Celsius), making them popular for use in low-temperature applications.

Features Constant speed, achieving synchronous speed. High power factor: A well-designed motor can achieve a power factor close to the value of 1.0. Compact size, lightweight, and low noise. High efficiency: During normal operation, there is no copper loss in the rotor. The high power factor results in a smaller rotor current and reduced copper losses in the rotor windings. The motor's speed is directly proportional to the frequency, simplifying the control system. The motor can be designed with multiple stages and low-speed high-torque capabilities, eliminating the need for a gearbox and enabling gearless transmission. Wide speed range, with a high-speed design that can reach up to 10,000 revolutions per minute (rpm).
