Magnetic function testing after high-temperature sintering Density detection after high-temperature sinteringAppearance scale inspection after high-temperature sinteringAnalysis of carbon, oxygen, and nitrogen after high-temperature sinteringFinally, a demagnetization curve is drawn using a magnetic tester to determine whether the blank meets the national standardDue to the large proportion of neodymium, iron, and boron being composed of iron elements, neodymium, iron, and boron are highly susceptible to oxidation when exposed to air or humid environments for a long time. Magnet electroplating is an important process for beautifying the appearance of magnets and adding magnets for preservation. The surface treatment of magnets mainly includes zinc, black zinc, nickel, black nickel, copper, gold, silver, epoxy resin, etc. The color and preservation time are also different depending on the surface electroplating, Each has its own advantages and disadvantages.Magnetization in the order of magnet orientation and formation is to magnetize magnetic: 12

Magnet orientation and forming sequence Some netizens want to know the orientation and forming order of magnets. Today, let's introduce them to everyone.The magnetic powder of the magnet has a low density in the green body after orientation, molding, and isostatic pressing, which is a negative factor in production. The green body also contains many pores, which simply adsorb a large amount of gas and water, bringing trouble and difficulty to the next process. Due to the low density of the green billet, high shortening rate during sintering, simple deformation, and oversized scale, it is necessary to conduct sintering, and the process requires high experience in sintering operations.During the sequential process of magnet orientation and molding, the green billet needs to go through two processes: sintering and aging when placed in the sintering furnace.1. Sintering; During a period of insulation in the high temperature range, the important improvement in sintering density is achieved. The relative density has increased f: 12

Picture of 0.5mm thick ultra-thin magnet and reference for magnetic force size The mini magnet is really small, and even using a coin as a reference is slightly insufficient. It seems difficult to imagine its specific size alone. Today, the permanent magnet manufacturer has brought you a 0.5mm thick neodymium iron boron thin sheet magnet thickness map and magnetic reference, hoping to be helpful for your work.The apparent magnetic size of a magnet, also known as Gauss, is directly related to the thickness of the magnet. The thicker the diameter or length, the stronger the magnetic force. According to Gauss meter measurements, a neodymium iron boron thin plate magnet with a diameter of 5 * 0.5mm has an apparent magnetic force of about 1000gs.If you have similar ultra-thin magnets (neodymium iron boron or ferrite) that require price evaluation or sample preparation, please contact the permanent magnet manufacturer.: 11

List of Main Application Fields of Sintered Neodymium Iron Boron Magnets of Various Grades Friends who have bought neodymium iron boron powerful magnets know that neodymium iron boron magnetic materials have multiple performance grades, because when you inquire with the magnet manufacturer or take samples, you are usually asked what performance grades or grades of neodymium iron boron you need. Magnets used for general packaging handbags and leather goods are usually N series, N35 or lower. The magnets used in the motor usually need to withstand high temperatures of over 100 degrees Celsius, so there are more H and SH materials. Therefore, when purchasing magnets, it is also necessary to pay attention, otherwise it may result in the purchased magnets not working properly and wasting money in vain.Below is an introduction to the main application fields of sintered neodymium iron boron magnetic materials of various grades. The N series and M series are mainly used in MRI, audio home appliance series products, VCM, magnetic separators, and consumer electronics. The H series is: 11

Some Physical Characteristics of Sintered Permanent Ferrite Magnets Permanent magnet ferrite materials are generally divided into two categories, namely sintered permanent magnet ferrite materials and bonded permanent magnet ferrite materials. Each type can also be divided into isotropic materials and anisotropic materials based on its performance.Our company's ferrite magnetic materials mainly produce sintered ferrite magnets, injection molded ferrite magnets, and ferrite magnetic components. Today, we will mainly talk about some physical properties of sintered permanent magnet ferrite, so that you can have a basic understanding of the physical properties of ferrite.What is the recovery magnetic permeability of ferrite? What is the distance between the Curie temperature of ferrite and the temperature? The density and resistivity of ferrite, etc.We have been specializing in the manufacturing of motor magnets for over ten years, carefully producing products for each customer, and satisfying them with quality. Welcome to process and customize with pi: 11

Discussion on the Function and Application of Plastic Magnetism (Injection Magnetism) Around Us When it comes to plastic magnets (injection molded magnets), I believe everyone is quite unfamiliar because there are very few places where people can directly see plastic magnets. Because these plastic magnets are stored inside electrical appliances and motors, we cannot directly see plastic magnets. However, plastic magnets play a very important role around us. Today, the magnet manufacturer Xiao Fu will explain in detail what plastic magnets are and their characteristics? And what kind of role these plastic magnets play around us, I hope everyone can understand these functions of plastic magnets.Plastic magnetic material is a new type of functional polymer composite material, which is an important basic material in the field of modern science and technology. Compared with sintered magnetic materials, magnetic plastics have the advantages of low density, high impact strength, controllable magnetic particle content, good chemical stability, and no cracking during use.
