Samarium Cobalt (SmCo) magnets are made by a sintering process and exist in two forms. The first is Sm1Co5(SmCo 1:5),which has a maximum energy product of between 14 and 24MGOe. The second and more common form is Sm2Co17(SmCo 2:17) which has a maximum energy product of between 22 and 32 MGOe. The main Sm2Co17 alloy is around 35% Samarium (Sm)and 60% Cobalt (Co)with the balance being from varying amounts of lron (Fe) Copper (Cu). Hafnium (Hf) and Zirconium (Zr). Praseodymium (Pr) may also be used. Sm1Co5 is made of only Sm and Co and has excellent corrosion resistance. â?¢ Advantages of SmCo Magnet: 1.Superior resistance to high temperature. 2. Excellent resistance to corrosion, no coating is needed for surface protecting. 3.High working temperature. 4.SmCo is suitable for machines with high magnetic requirements and good for strict working environment requirement.
AINiCo is composed primarily of Aluminum Nickel Cobalt and also Copper and Titanium. They are manufactured through either casting or sintering process. Cast AINiCo may be manufactured in complex shapes such as horseshoes not possible with other magnet materials. Sintered AINiCo offer slightly lower magnetic properties but better mechanical characteristics. it can be efficiently magnetized in any direction, and for anisotropic AINiComagnet, it generally has greater magnetic capacitive in a preferred orientation than isotropic types. AINiCo is hard and brittle, Machining or drilling cannot therefore be accomplished by ordinary methods. Holes are usually cored in at the foundry, and magnets are cast close to final size and then finish machined to closer tolerances. â?¢ Advantages of AlNiCo Magnet: 1.Customized designs are available. 2.Max working temperature can be as high as 550�°C. 3.Disadvantage: Br and BH(max)are not as high as rare earth magnet. 4.High energies and relatively low coercivity. 5.High magnetic flux density; low mold charge stable temperature properties; easy to shap.
Ferrite Magnet is manufactured from oxide material by powder metallurgical process. Its advantages include: low-cost excellent corrosion resistance, resistance to be demagnetized etc. The normal working temperature of Ferrite Magnet is between-40C and +250C.It can be magnetized before or after assembling. Generally, Ferrite Magnet can be machined to regular shapes like segments, blocks, rings and discs etc. The normal grades for sintered Ferrite Magnets are Y10,TY25, Y30, Y30BH, Y35, etc. Advantages of Ferrite Magnet: Ferrites have isotropic characteristics, weak magnetic performance, has the same magnetic performance in any direction, multipolar magnetic charge. The main raw material of ferrite is oxides, so it is not corroded by high temperature, high humidity or chemicals (except strong acid and base); with excellent diamagnetic impedance, no flux loss before and after assembly and magnetic charging; working temperature is-40C to + 250C, poor temperature coefficient; Br temperature coefficient is-0.2% /C, 0.2% under Br, etc. per 1 Cincrease; high hardness, wire cutting and grinding; ferrite is brittle and fragile during production and transportation. magnetic requirements and good for strict working environment requirement.
A Fridge magnet is an ornament, often whimsical, attached to a small magnet, which is used to post items such as shopping lists, child art or reminders on a refrigerator door, or which simply serves as decoration. Refrigerator magnets come in a wide variety of shapes and sizes, and may have promotional messages placed on them. Refrigerator magnets are popular souvenir and collectible objects.

Alnico magnet is mainly having Al, Ni, Co, Fe and others metal, is mainly used in Motors, Meters, Odometer, Speakers, Sensors, Guitar, Education, etc.
Flexible magnet is made of ferrite powder bonded with macromolecule compounds, such as CPE, NBR, CR, PVC, nylon, and PP etc. It is also called rubber magnet or plastic magnet because of its bond materials. It features in flexibility, and thus can be made into rolls, sheets, strips, blocks, rings and so on, through extruding, calendering, injecting, molding.
Description: 1.These types of grids are used for separating any unwanted ferrous particle found in powder ed or granulated products, liquid or dry. Magnetic grids are suitable for contamination with Fe particles as small as 0.1 mm. 2.The placement of these types of grids can be in many different positions. Normally, they are placed in the entrance of hoppers, pipes or channels. 3.Magnetic grids usually made of Neodymium magnets(3000-12000Gs) and seamless 304 or 316 stainless tubes, can be fine polished and fully welded to meet food grade or pharmacy application. 4.Usually the max working temperature is 80â??, we can offer up to 350â?? to meet your special applications. Standard sizes: The Circular Magnetic Separator Grid can be bought in 50mm increments in sizes between 100mm diameter and 500mm diameter. Application: Magnetic separators are used to extract and remove ferromagnetic materials from liquid or solid mixtures. The separator grids and rods from EMKEX are widely applied in food & pharmaceutical industries.Placed in the materials flow line, the grids and rods can remove ferrous contamination from sugar, rice, flour, tea, animal feed, plastic granulates, shredded paper, chemicals and shredded copper, etc.. Ferromagnetic materials including most mild steels, a few stainless steels, iron, nickel, cobalt and manganese can be picked up by the separators. Non-magnetic materials, such as aluminum, silver, gold, many stainless steels and copper, will not be extracted by magnets.
