Tianjin Nibboh Magnets Co., Ltd
Tianjin Nibboh Magnets Co., Ltd is a privately owned producer of permanent magnets and magnetic assembly located in Tianjin China with more than 10 years experience. We occupy about 10,000 square meters of plant and office space, with capacity annually 300 tons Bonded NdFeB magnet and 1000 tons Sintered NdFeB magnet
· ·The registered capital of the company is 5 million yuan
· The company covers an area of about 10000 square meters
· The production capacity reaches 7000 tons
Sintered NdFeB magent has been commercially available since Novermber 1983. NdFeB magnets offer the higher energy product of any material today and are available in very wide range of shapes, sizes and grade.
Bonded NdFeB magnet represents one of the more important groups of magnetic materials available today. They can be tailored to suit a wide range of magnetic and physical strength, size, shape, and temperature characteristics.
Samarium cobalt (SmCo) magnets, offer the designer a tremendous combination of extremely high magnetic properties, outstanding thermal stability and excellent corrosion resistance.
Hard ferrite (ceramic) magnets are mainly formed by barium ferrite and Strontium ferrite. Even though they exhibit low energy (compared with other permanent magnet materials) and are relatively brittle and hard,
Plastic magnet is different from the traditional magnetic craft which made by mixing the magnetic particle with plastic medium, mixed and heated by the injection machine and then rip the mixture into the mould to get different shapes of production, this kind of process makes the plastic magnet has some unique advantages: the precise magnet with complex shape can be made very easily; during the subsequent assembly and use the magnet is hard to crack; it can form in one piece with inlaid element easily.
AlNiCo Magnets are fored by casting or powder metallurgical processes. Both of them have good corrosion resistance characteristic, no coating is needed for surface protection. AlNiCo remains the workhorse of the permanent magnet industry and can be relied upon to deliver impressive flux density at an economical price. AlNiCo also boasts the lowest temperature coefficient of any commercial magnet material(.02% per degree centigrade) allowing for excellent stability over a wide temperature range. The maximum working temperature can be higher than 400 degree for this magnets.
Notes on the application of permanent magnet materials
The actual magnetic properties of permanent magnet materials are related to the specific manufacturing process of the factory, and there is often a certain deviation between the values and the data specified in the standard. The same brand of permanent magnet material, different factories or different batches of the same factory will have certain magnetic differences. For the shape and size of the permanent magnet actually used in the motor, there will be some differences between its magnetic properties and the standard data.
The main properties of permanent magnet materials
The magnetic induction intensity value of the permanent magnet material when the external magnetic field is zero after the material is magnetized to saturation. This index data is directly related to the magnetic density of the air gap in the motor. The higher the magnetic induction intensity value, the higher the air gap magnetic density of the motor may be, the torque constant, back potential coefficient and other main indicators of the motor will reach the best value, the electrical load and magnetic load value relationship of the motor may be the most reasonable, and the efficiency can reach the best.
