General Division of Magnet
---NdFeB magnets, mainly made from Neodymium, Iron, Boron, has earned reputation on its high qualities and competitive price, it has excellent properties of high remanence, coercivity and Max. Energy Products. It's widely used in motors, generators, electroacoustics, hard-disc drives, magnetic separators, permanent magnet bearing, holding system, switches, NMR-analysis equipment and MRI-tomographs, relay and etc.

--- Flexible & Plastic magnets, The Flexible & Plastic magnets is a kind of composite magnetic material, made by calendering, extrusion and injection, it's like rubber, easily to be fabricated. It is widely used in industry and civil appliance, such as, motor, signposts, drawing board locking system, instruments and so on.

---Ferrite magnets, made from iron oxide, SrCO3, (or BaCO3)and other additives, having a relatively low recoil permeability, results in highly resistant to an external magnetic fields, moreover, it's low in costs, and widely used in motors, generators, electroacoustics, separators, holding system, telecommunication system and etc.

---AlNiCo magnets, the base constituents are Nickel, Cobalt, Aluminum and iron, has excellent corrosion resistance and temperature stability. It's hard and brittle, but can be manufactured in complex shapes which are impossible with other magnetic materials. With the characteristics of high induction remanence, specific energy and a lower variation to temperature, it can be used at quite high operating temperature. It's widely used in motors, motors, senor, meters, magnetic separators, loudspeaker, holding system and etc.

---SmCo magnets, made from Cobalt and rare earth, is a high performance permanent magnet. It has very strong uniaxial magnetic anisotropy originating from crystalline structure which gives a high specific energy and exceptional resistance to demagnetization in the presence of opposing field, and at same time a good remanence and temperature coefficient. It's widely used in motors, watch, transducers, instruments, positional detector, generators, radar and etc.

--- Bonded NdFeB magnets,  its compound of plastic, rubber and rare-earth materials, the shapes are formed by ways of compressing, injecting, extruding and etc. It has high Intrinsic Coercive force and good magnetic consistency in mass production. It's widely used in motor, computer application and so on.

--- Magnet system & assemblies, Assemblies using metal and other components, magnets can be fabricated by adhering magnets with adhesives to suit a range of environment, by mechanically fastening magnets, or by a combination of these methods. 


NdFeB Magnet

Neodymium-iron-boron is a permanent magnetic material with metallic composite of Nd2Fe14B as the base. Compared with the casting of Al-Ni-Co permanent magnetic materials and permanent magnetic ferrite,neodymium-iron-boron has stronger coactivity and (BH)max,which can attract heavy objects weighing 640 times its weight. Its merit of higher energy density results in its widely application in modern industry and electronic technology, which makes the small size, light weight and thin set of instruments, audio and engines, magnetic separation and magnetizing equipment a possibility.


Characters of NdFeB:

The merits of neodymium-iron-boron is its excellent performance and cost ratio and good machinery feature of easy machining. Its demerits lie in its low curie temperature, bad thermal feature, easy erosion, which should be improved to achieve desired requirement with the adjustment of chemical composition and surface treatment.


Permanent Magnet Lifter

Made of high-performance magnetic material, so it is small, light and strong in adsorption. Unique magnetic circuit and nearly no remanence. High safety coefficient and max. pull-off strength is 3.5 times of the rated lifting force. With security button, the handle can be operated by one hand, safe and convenient. There is V-shaped groove at the bottom of the lifter and it can lift corresponding round steel and steel plates with permanent magnetic force and without power supply. It can be operated in field and used to lift and carry steel products, mechanical parts and moulds.


Key feature of Neodymium magnet
High energy and high magnetic field for size
Very high resistance ability to demagnetization
Need to consider the maximum working temperature
Moderately Priced
Material is corrosive and should be coated for long-term maximum energy output.


Key feature of SmCo magnet / Samarium Cobalt magnet
High magnetic energy output
High resistance ability to demagnetization.
Good temperature stability
Not need to be coated.
Expensive material


Key feature of Ceramic magnet/ Ferrite magnet
High resistance ability to demagnetization.
Least expensive material compared to SmCo, Alnico and Neodymium magnet.
Not easy to form into complicated shape, due to manufacturing process
Grinding process is needed.
Stable and do not need to be coated.


Key feature for Cast alnico magnet
Will cast to varieties of shapes and sizes
Very temperature stable, great for high heat applications
Maximum working temperature 975° - 1020° F
Does not lend itself to conventional machining (hard and brittle)
High residual induction and energy product compared to ferrite magnet
Low coercive force compared to ferrite and neodymium magnet (more subject to demagnetization)


Key feature for Sintered alnico magnet
Pressed to close tolerance/minimal grinding to finish
Mechanically strongest of alnico
Very temperature stable, great for high heat applications
Maximum working temperature 975° - 1020° F
Does not lend itself to conventional machining (hard and brittle)
High residual induction and energy product compared to ferrite magnet
Low coercive force compared to ferrite and neodymium magnet (more subject to demagnetization)
