Aluminum, nickel cobalt and sagnic cobalt magnets Aluminum nickel cobalt (Alnico) is the earliest permanent magnet material developed. It is a alloy composed of aluminum, nickel, cobalt, iron, and other trace metal elements. According to different production processes, it is divided into sintered aluminum nickel cobalt (Sinteered Alnico) and cast aluminum nickel cobalt (Cast Alnico). The shape of the product is mostly round and square. The casting process can be processed and produced into different sizes and shapes; compared with the casting process, sintering products are limited to small sizes, and the blank size tolerance is better than the blanking of the cast product. Machining is good. In the permanent magnet material, the cast aluminum nickel cobalt permanent magnet has a minimum reversible temperature coefficient, and the operating temperature can be as high as 600 ° C. Aluminum nickel cobalt permanent magnet products are widely used in various instrument and other applications. The） cobalt (SMCO) is divided into SMCO5 and SM: 06

Rubber magnet Rubber Magnet is one of the iron oxygen magnetic series. It is softened and squeezed out by bonding iron oxygen powder and synthetic rubber. Elasticity and twisted magnets. It can be processed into strips, curls, sheets, and various complex shapes. The rubber magnet is made of magnetic powder (Sro6fe2O3), polyethylene (CPE), and other additives (EBSO, DOP), and is manufactured by squeezing and pressure. The rubber magnetic material can be the same or heterogeneous. It is made of iron oxygen magnetic powder, CPE and certain trace elements, which can be bent, twisted, and can be rolled. It does not need more mechanical processing to use it. It can also be trimmed according to the required size. The rubber magnet can also be re -enabled PVC, gum, UV oil, etc. according to customer requirements. Its magnetic energy accumulates between 0.60 and 1.50 mgoe. Application of rubber magnetic materials: refrigerators, message notice racks, fixing objects in metal body for fasteners such as adverti: 06

Permanent magnet classification (1) Alloy permanent magnet materialIncluding rare earth permanent magnet materials (钕 iron boron ND2FE14B), lattice cobalt (SMCO), aluminum nickel cobalt (Alnico)(2) Ferrite material (Ferrite)Classified according to the production processAccording to different production processes, it is divided into: sintering iron oxygen, bonding iron oxygen, and injection of iron oxygen. These three processes are divided into equal and heterogeneous magnets based on the orientation of magnetic crystals. [1]The above is the main permanent magnet material on the market, and some are eliminated due to the production process or cost reasons. ), FE-Co-V (Iron Cobalt), MNBI (Manganese): 06

Rare earth permanent magnet material Rare earth permanent magnet material ( iron boron ND2FE14B) is divided into the following three types according to different production processes:(1) Bonding （b （(Bonded NDFEB)Plug -in iron boron is a composite cymbal iron boron permanent magnet with a composite cymbal iron boron -boron permanent mixing with adhesives such as resin, plastic or low melting point metal, and then using compression, squeezing or injection molding. The product is formed first, and there is no need to make a secondary processing, which can be directly made into various complex shapes. Each direction of bonding the iron boron is magnetic, and it can be processed into iron boron compressed molds and injection molding molds. High precision, excellent magnetic properties, good corrosion resistance, and good temperature stability.(2) Sintened NDFEBThe sintering iron boron permanent magnet is smelted after being grinded by the airflow. The stubborn power is very high and has a high magnetic performance. Its maximu: 06

Strip magnetic performance 1. Anti -magneticAnti -magnetic is a magnetic phenomenon that is a magnetic field in some categories. When it is in the external plus magnetic field, it will be a magnetic phenomenon of the weak repulsion generated by the magnetic field.2. MagneticMagneticity refers to the magnetic state of a material. Some materials can be affected by the external magnetic field, producing the characteristics of the same magnetic vector. Such substances have a positive magnetization rate. The phenomenon opposite to the magneticity is called anti -magnetic.3. MagneticMagnetic refers to the magnetic state of a material, with spontaneous magnetic phenomenon. Among the materials are the most widely known, so they are named.After being magnetized under the action of external magnetic fields, some materials can still maintain its magnetization and be magnetic even if the external magnetic field disappears, that is, the so -called spontaneous magnetization phenomenon. All permanent magnets have iron magnetic: 05

Strip magnetic material 1. Tie iron boron magnetIt is the most commercialized magnetic magnet, which is known as the magnetic king. It has a high magnetic performance of more than 10 times that its maximum magnetic energy accumulation (BHMAX) is high. Its mechanical processing performance is also quite good. The highest working temperature can reach 200 degrees Celsius. In addition, its texture, stable performance, and good cost performance, so its application is extremely wide. However, because of its strong chemical activity, it must be treated on its surface coating. (Such as plating Zn, Ni, electric swimming, passivation, etc.).2, iron oxygen magnetIt is manufactured by ceramic craftsmanship. The texture is relatively hard and is crispy material. Because iron oxygen magnets have good temperature resistance, low price, and moderate performance, it has become the most widely used permanent magnet.3. Aluminum nickel cobalt magnetIt is a alloy composed of aluminum, nickel, cobalt, iron, and other trace metal: 05
