Magnetic environment test When designing and evaluating the application of magnets, in addition to considering performance requirements, the most important thing is whether the magnet can exert its effectiveness in the actual environment and the duration of its ability to last. Environmental testing is a quality management program established for this purpose, which simulates the actual environment that magnets may face, observes changes in magnets, and enables magnets to truly meet the requirements and standards of actual operation.Accelerated magnet aging test is one of the most commonly used environmental tests when detecting magnets. This series of experiments utilizes increased and controlled environmental conditions such as pressure, temperature, humidity, and contact with substances to enhance the potential environmental impact on magnets. In other words, we simulate the changes that magnets may undergo in actual environments over a long period of time by exposing them to extreme experimental environment: 19

Advantages and disadvantages of samarium cobalt permanent magnets Advantages/Benefits:(1) Can be used in extremely cold conditions.(2) SmCo can be used at temperatures up to+300 degrees Celsius (572F) and up to+350 degrees Celsius (662F).(3) High coercivity (Hci) to resist demagnetization.(4) Above+150 to+180 degrees Celsius (302-356F), samarium cobalt magnets begin to provide higher performance levels than neodymium iron boron magnets.(5) Samarium cobalt performs well in terms of corrosion resistance.(6) The extremely low field strength varies with temperature.Disadvantages/Disadvantages(1) Under very humid conditions, Sm2Co17 should be coated with a protective coating to minimize any risk of surface corrosion. Sm1Co5 does not rust because it does not contain iron.(2) The general cost is higher than neodymium iron boron.(3) All magnets are very brittle, but samarium cobalt magnets are the most brittle.: 19

Rare earth magnets and non rare earth magnets What is a rare earth magnet? What is a non rare earth magnet? Today, this article takes you to learn more.Non rare earth magnets have a long history, and their mass production and industrial application gradually matured in the mid-20th century. It was not until the late 20th century that rare earth magnets emerged with the development of powder metallurgy technology, and non rare earth magnets were distinguished from them.Rare earth magnets are made by smelting the combination of rare earth elements and ferromagnetic elements, which can generate a strong magnetic field and have excellent magnetic retention. Its magnets are brittle and prone to cracking, and are prone to corrosion and loss. Therefore, other metals are generally used as coatings to protect rare earth magnets.Common rare earth magnets include: samarium cobalt magnets developed in the 1970s, which were the first batch of mass-produced rare earth magnets; Another mainstream neodymium iron boron magnet was launched in 1984.: 19

Do you know the content of rare earth elements in magnets? Rare earth elements are a group of 17 metallic elements, including fifteen lanthanide elements on the periodic table, as well as scandium and yttrium. They are essential components of over 200 widely used products, especially high-tech consumer products such as cellular phones, computer hard drives, electric and hybrid vehicles, as well as flat panel displays and televisions. Important national defense applications include electronic displays, guidance systems, lasers, radar, and sonar systems. Although the amount of rare earth elements used in a product may not be an important component of its weight, value, or volume, rare earth elements are necessary for equipment operation. For example, magnets made of rare earth elements typically only account for a small portion of the total weight, but without them, the spindle motors and voice coils of desktop and laptop computers would not be possible.What are the elements used to manufacture permanent magnets?Including samarium, neodymium, pr: 18

Introduction to the magnetization direction and production cycle of neodymium iron boron block magnets There are not many online introductions about neodymium iron boron strong square magnets. Today, magnet manufacturer Karich Xiaofu provides a detailed introduction on the magnetization direction and production cycle of square magnets.First of all, let's talk about the delivery time of neodymium iron boron square magnets: The delivery time of square magnets is related to the order quantity and processing difficulty, usually taking about 7-10 days. This delivery time is related to the order arrangement and production volume of the magnet manufacturer. After confirming the unit price of the magnet, the delivery time still needs to be further negotiated, so as not to cause discomfort for both parties due to the delivery time!Many friends are confused about the magnetization of a square magnet and do not understand how to express it, so customers often make mistakes. For example, a square magnet is 15mm long, 4mm wide, and 3mm thick. If a 3 * 15 surface is required as a strong magnetic: 16
