Block Neodymium Magnet
square Block Neodymium Magnet
rectangular Block Neodymium Magnet
Horizon supply Neodymium magnets in square and rectangular block shaped. Usually we call them magnetic blocks, Neodymium bar magnets or rectangular Neodymium magnets. The block magnets are always used in industrial markets and small blocks may be used as craft magnets.
Neodymium magnets known as NdFeB, Neodymium-Iron-Boron, Neo, NIB or Rare Earth Neodymium magnets, are the third generation of rare earth permanent magnets. They offer the highest energy product of any material today and are available in a very wide range of shapes, sizes and grades. These qualities have made NdFeB magnets preferable over the commonly used larger and less powerful Ferrite magnets.
Although the Curie temperature for NdFeB materials is 310-370ºC, some irreversible loss of output may be expected at even moderate temperatures. NdFeB magnets also have a moderately high reversible temperature coefficient of Br which reduces total magnetic output as temperature rises. Selection of NdFeB instead of SmCo, for example, is a function of the maximum temperature of the application, required magnetic output at typical use temperature and total cost of the system.
However, they are sensitive to oxidization and can develop corrosion, so they require surface protection like phosphate, passivation, Ni, NiCuNi, Zn, Epoxy, NiCuNi+Sn or others.Neodymium bar magnets Factory

rare earth magnet Size:
Normal Size Range: L (Length): 1~180mm, W (Width): , T (Thickness):
Maximum Size: Rectangular: L180 x W80 xT60mm, Square: L100 x W100 xT70mm
Minimum Size: L1 x W1 x
Orientation Direction Size: Lower than 80mm
Tolerance: Generally +/, Particularly +/
Machining Method:
Generally the finished block of small dimension is sliced from the big block directly. If the dimension of one or two directions is large, for example >60mm, it should need grinding and EDM cutting, due to the limits of the slicing machine. If all three directions are too large, only grinding is enough. Prior to coating, the small block needs vibration tumbling and the big block needs manual chamfering.
Main Application:
Electric motors, wind turbines, pump couplings, chemical pumps, sensors, magnetic sputtering cathodes, magnetic assemblies, etc.
Main Test Items Prior to Delivery:
In order to ensure NdFeB magnets to meet requirements, we main test following items: size, weight loss, magnetic properties, flux, flux density, angle deviation, magnetic loss, appearance, coating thickness, corrosion resistance, etc.

The big axially oriented cylinder(>D10mm) can be pressed to shape and then grinded and sliced. But sometimes the big axially oriented cylinder should be core-drilled or EDM cut from a block, so as to ensure the magnetic properties especially for high end grades or shorten the lead time. Prior to coating, the small cylinder needs vibration tumbling and the big cylinder needs manual chamfering.

traction motors Featured Motor Magnet
elevator motors Featured Motor Magnet Factory
Horizon have been focusing on the development and production of high end series of NdFeB rare earth permanent magnets, which are widely used in permanent magnet motors and generators.
Due to their advantage, NdFeB rare earth magnets have become one of the most important components of permanent magnet motors and generators, whose performance and life time mainly depends on the quality of magnets. Generally speaking, the working environment to motors and generators is very harsh. In order to adapt to this working environment, we have been devoting ourselves to research and develop NdFeB rare earth magnets specially used for permanent magnet motors and generators since its foundation. For this application, the magnets are available in a wide range of shapes such as block, ring, segment, loaf, wedge, etc.
Currently we are producing serials of high end grades, like H, SH, UH, EH and AH for NdFeB with following three characteristics:
High intrinsic coercivity Hcj: high to >35kOe (>2785 kA/m) which increases magnets demagnetizing resistance
Low reversible temperature coefficients: low to α(Br)< and β(Hcj)< which increases magnets temperature stability
Low weight loss: low to 2~5mg/cm2 in HAST testing condition: 130ºC, 95% RH, ATM, 20 days which increases magnets corrosion resistance
Although the low weight loss material improves its corrosion resistance, the coating is still often required by customers. If customers require coating, we suggest magnets be phosphated or passivated. However, more and more customers change to use magnets without any coating, because uncoated magnets have much better glue cohesiveness than coated magnets.
Servo motors, elevator motors, traction motors, linear motors, stepper motors, disc type motors, wind generators, etc.

Stable working Laminated Magnet
Neodymium Laminated Magnet
SmCo Laminated Magnet
Laminated magnet is produced with several pieces of magnets glued so as to reach insulation effect between those pieces. Therefore sometimes laminated magnet is also called insulated magnet or glued magnet. Laminated SmCo or laminated Neodymium rare earth magnets are proven to reduce the eddy current loss for the high efficiency motors.
The fewer the eddy current loss becomes, the lower the heat generates to enhance higher efficiency. Nowadays the demand of laminated rare earth magnets has been going up, because aerospace, industrial markets and promising EV especially are dedicating to pursuing the balance between motor power and heat. Thanks to knowledge in electric motor and extensive experience in laminated magnets, Horizon can work with customers to improve motor performance through ensuring laminated magnets with following characteristics:
Stable working at temperature up to 200˚C
Consistency of insulation guaranteed
Insulation layer ranging 25 -100 μm
Magnet layer with thickness from and up in a wide of shapes like block, loaf, segment and wedge
Magnet material in SmCo or Neodymium

precast concrete formworks Button Magnet
quick operation Button Magnet
customized Button Magnet
2100Kg button magnet is magnetic shuttering solutions for precast concrete formworks!
In fact, construction market is too small compared to all Neodymium magnet markets, and Neodymium magnet is also too small to extensive construction accessories. Almost none of magnet suppliers have interest or knowledge in the application of magnet in the construction market. We focus our assembly attention on developing and manufacturing Neodymium magnet assemblies for the construction industry, especially precast concrete industry.
The precast concrete industry has been searching for a more economical and efficient formwork method. In the past, some conventional magnets were used to position and fasten the formwork, but considerable mechanical loads with a hammer were required, which was easy to damage the magnets and the surface of the expensive formwork tables as well. Thanks to Horizon’s knowledge and experienced experts in magnet and construction fields, in order to facilitate the formwork activities, Horizon are developing and manufacturing our own shuttering magnet to solve this problem successfully.
Our button magnet provides quick operation leading to improved efficiency when setting out and breaking down the formwork. It consists of a switchable NdFeB magnet unit and a steel casing which forms a certain designed magnetic circuit. By pressing the button on top of the steel casing, this magnetic force is activated so that this magnet can fasten the formwork to the steel table tightly. In a deactivated mode, the magnet is easy to position. By means of two threaded holes integrated on the top, this magnet can be equipped with various adapters, which can provide unlimited options for use.
Use with wood or steel formworks
Easy to operate
Simple and exact positioning
Adhesive force ranging from 450 Kg to 3100 Kg
Avoid welding or bolting to the formwork table therefore preserving surface finish
Same magnet can be used for different purposes
Integrated threaded holes to adapt formwork
Adapters to be custom made
