Let's learn about the development of neodymium-iron-boron magnets together with Fenfa Magnets!
There are numerous pipeline systems around us, such as water pipes and gas pipelines. Among them, steel pipes are the ideal materials for laying pipelines. Compared with steel pipes, pipes made of other materials have advantages in hardness. However, in the past, there were many challenges in laying pipeline systems.
At that time, the manufacturing technology of steel pipes was not very advanced. Since I was engaged in steel pipe production at that time, its various performances were not so good. Especially, the toughness of steel pipes was insufficient, and there were always a lot of troubles when connecting steel pipes. For example, when connecting them, you needed to use many other connectors to join the two steel pipes together. Or, when the openings of steel pipes enlarged or there were cracks in the steel pipes.
Every time such problems occurred, there would always be some losses. But now all these problems have disappeared. In other words, in the current pipeline systems, tapered steel pipes are used for pipelines, and tapered steel pipes can solve the problems that occurred during pipeline connection very well. For example, when connecting, there is no need to use additional connectors for two different pipes. As a kind of tapered steel pipe, it has very strict standards for parameters in all directions of the steel pipe. Strict compliance will lead to the expected connection of pipes with different standards. The connection state of steel pipes is good, and you can connect them as expected.
Neodymium-iron-boron magnets can convert the magnetic function changes of active elements into electrical signals through magnetic fields, electric currents, stress and strain, temperature, and light, and determine the corresponding physical quantities in this way. It features non-contact measurement, is hardly affected by the signals being measured, is resistant to pollution and noise, can work reliably even in harsh environments, and is durable. Therefore, sensors are used in aspects ranging from medical and health care to people's daily lives, as well as in national defense, aerospace, and the national economy.
All neodymium-iron-boron magnets are usually assembled and operated inside machines and equipment. Modern machines are compact, simple, multi-functional, and flexible, and are developing towards the direction of intelligence. Please ensure that even if physical quantities change in a very small space, sensors can respond with high activity and at a high speed. The sensors themselves need to be smaller and lighter, and they are eager to improve speed, detection resolution, and activity.
In the future, the progress of integrated circuit semiconductor manufacturing technology, microelectromechanical systems (MEMS) technology, micro-assembly technology promotion and operation, planar coil micro-magnetic device manufacturing technology, new materials such as magnetic thin films, amorphous materials, and multilayer films, as well as the progress of nano-magnetic field lines and characterization methods have laid a reliable foundation for the miniaturization of neodymium-iron-boron strong magnets. High-performance, miniaturized neodymium-iron-boron magnets that make full use of various new effects are being introduced to department stores. The AMR thin-film moving elements and sensors released last semester, the thin-film fluxgate magnetometers with practical application potential, and the wireless magnetoelastic micro-sensor arrays are all typical examples. The following briefly introduces the working principles, bottom structures, and main technical features of several neodymium-iron-boron micro-magnets. Fortune Magnet Industry Technology
The development and operation of neodymium-iron-boron strong magnets have created huge economic, technical, and social benefits. In addition, industrial automation, process integration, office automation, and the modernization of daily homes have also been completed rapidly. They are playing an increasingly important role in the transformation of traditional industries, resource exploration and comprehensive utilization, environmental protection, biotechnology, and communications.
According to the research company iSuppli, the demand for magnetic field sensor chips in the automotive, industrial, and cost management industries will be weak in 2010. The department store sales were $821 million in 2009 and are expected to reach $1.4 billion in 2013. In terms of shipment volume, it increased from 2.8 billion units in 2009 to more than 5 billion units in 2013. There is also the issue of gaps.
Neodymium-iron-boron magnets can have performance grades such as N35 - N52 performance, M series 35M - 52M performance, H series 33H - 52H performance, SH series 33SH - 48SH performance, UH series 30UH - 45UH performance, EH series 28EH - 40EH performance, and AH series 28AH - 38AH performance. The products are widely used in fields such as electronic appliances, hardware and plastics, lighting fixtures, wind power generation, aviation instruments, medical machinery, the automotive industry, magnetic levitation tools, detection instruments, electrical machinery and electroacoustics, and sports equipment.
