Product Description
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.
We are Block Neodymium Magnet Supplier.
Characteristics:
Genuine Neodymium magnet, without La Lanthanum or Ce Cerium to destroy magnet quality
Outstanding magnetic properties – Br high to 14.5 kGs 1. 45T and BHmax high to 52 MGOe 414 kJ/m3
High demagnetization resistance –maximum Hcj higher than 35 kOe 2785 kA/m
High working temperature – maximum working temperature high to 230ºC
Wide range of grades with new ones regularly being developed – High magnetic properties, AH grades or Low Weight Loss materials and so on.
rare earth magnet Size:
Normal Size Range: L Length: 1180mm, W Width: 0.4100mm, T Thickness: 0.4120mm
Maximum Size: Rectangular: L180 x W80 xT60mm, Square: L100 x W100 xT70mm
Minimum Size: L1 x W1 x T0.4mm
Orientation Direction Size: Lower than 80mm
Tolerance: Generally /-0.1mm, Particularly /-0.03mm
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.
rectangular Block Neodymium Magnet 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.

About Us
Not only a magnet supplier, but also a magnetic solutions supplier!
Nowadays the technology is developing daily, and then new materials and applications are developed as well. As a leading magnet company, we take advantage of our Neodymium magnets and magnetic solutions to assist you in your increased projects related to magnets.
In order to fullfil this commitment, Ningbo Horizon Magnetic Technologies Co., Ltd was founded by a professional team with a depth of expertise and breadth of experience in the magnet field. We are specialized in the development and production of sintered Neodymium magnets and related magnetic assemblies with facilities in Ningbo, China which is the source of rare earth permanent magnets.
In order to keep with overwhelming customers’ needs, we are equipped with the state-of-the-art research, production and testing equipments, which help us enjoy steady but increasing growth. Because we are a medium-sized company and supply 600 tons of Neodymium magnets and millions of magnetic assemblies per year, we are able to react quickly to the requirements of our customers throughout the world. Our rare earth magnets and magnetic assemblies are popular with hundreds of customers in the fields of electric motor, construction, industrial, defense aerospace, oil gas, and automation robtics. Due to our own medidum size, we quite understand medium-sized companies’ situations, requirements and difficulty. Therefore we are dedicated to cooperating with and helping medium-sized customers out.
When we are supplying customers with all series of Neodymium rare earth magnets, we focus on research and production of high end series which are mainly used in electric motors, such as servo motors, linear motors, traction motors, compressor motors, etc. Thanks to our knowledge in precast concrete industry, for assemblies we concentrate on magnetic assemblies such as shuttering magnets, triangle magnet chamfers, inserted fixing magnets, pot magnets, etc.
You can tell us about your project and we can assist you from idea to serial production. Our technicians and production experts can contribute valuable time and cost effective measures at any stage of your project. No matter whether you are currently designing, developing or in production, Horizon can make a difference.
