NdFeB is the rare earth permanent magnet with the highest magnetic energy and coercive force produced by powder metallurgy process with metal Nd, Fe and BFe as the main raw materials. Widely used in all types of motors and speakers and audio. It is an ideal material for developing new products with high quality requirements, small size and light weight. The shape includes various specifications such as square, cylinder, ring, tile shape, etc. The surface plating includes: galvanization, nickel plating, nickel-plated copper-nickel, phosphating, copper-plated epoxy, phosphating epoxy, gold plating, etc. The grades can meet the needs of all types of customers.
The SmCo has high temperature resistance and strong magnetic force. It combines the advantages of NdFeB and AlNiCo, but as a single characteristic, it is inferior to the performance of the two products. It has a high magnetic energy product and a very low temperature coefficient. It can be used at temperatures up to 350 degrees Celsius. It has strong corrosion resistance and oxidation resistance and usually does not require plating. It can be used in instruments, meters, micro-motors, electro-acoustic devices, microwave devices, magnetic rotating devices, motors, sensors, detectors, engines, radar and other high-tech fields.
The magnetic component is a combination of a magnetic element and a magnetically permeable element to increase the magnetic flux density of the magnetic component and increase the magnetic flux of the magnetic component, thereby enhancing the magnetic force and the material-saving magnetic component. Generally, the magnetic force generated by the permanent magnet is used to achieve various effects; in the case of rare earth materials, the permanent magnet made of the rare earth material has a relatively high coercive force and a magnetic energy product, and is used in a notebook, a mobile phone, All kinds of products, such as generators and electric vehicles, rely on rare earth permanent magnets to provide sufficient magnetic force to exert the highest magnetic effect. However, the production of rare earth materials is scarce and the price is constantly rising, which makes the production of various products relatively. The cost is high, so how to save magnetic materials, can achieve the required magnetic force, and even increase the magnetic force, magnetic components have a merit.
The ferrite magnet is a sintered permanent magnet material composed of tantalum and niobium iron. In addition to strong anti-demagnetization properties, this magnetic material has the advantage of low cost. Ferrite magnets are rigid and brittle and require special machining processes. The opposite-sense magnets are oriented in the manufacturing direction and must be magnetized in the direction in which they are taken, while their isotropic magnets can be magnetized in any direction because they are not oriented, although a slightly stronger magnetic induction is found on the smallest side of the pressure-receiving surface. The magnetic energy product ranges from 1.1 MGOe to 4.0 MGOe. Due to its low cost, ferrite magnets have a wide range of applications, from motors and speakers to toys and crafts, making them the most widely used permanent magnet materials.
It is a kind of ferrite magnetic material series. It is made of bonded ferrite powder and synthetic rubber. It is made of soft, flexible and twistable magnets by extrusion, calendering and injection molding. . It can be processed into strips, rolls, sheets and various complex shapes.
The rubber magnet is composed of magnetic powder (SrO6Fe2O3), polyethylene (CPE) and other additives (EBSO, DOP), and is produced by extrusion and calendering. The rubber magnetic material can be homogenous or heterosexual. It is made of ferrite magnetic powder, CPE and some trace elements, and can be bent, sturdy and rollable. It can be used without more machining, or it can be shaped according to the required size. Rubber magnetic can also be used to re-apply PVC, adhesive, UV oil, etc. according to customer requirements. Its magnetic energy product is between 0.60 and 1.50 MGOe.
