Widely used in industries ranging from automotive to jewelry, which offers a unique combination of hardness, corrosion resistance, and aesthetic appeal. In this article, we’ll explore what PVD coating is, how it works, its benefits, […]

AlNiCo Magnets: Everyday Applications and Why They Matter

Introduction AlNiCo magnets, made from aluminum, nickel, and cobalt, are one of the oldest types of permanent magnets. Despite the rise of rare-earth magnets like neodymium, AlNiCo magnets continue to play a vital role in various everyday applications. Their high magnetic strength, temperature stability, and corrosion resistance make them indispensable in many fields. In this […]

Which one is more accurate for AlNiCo magnetism, Gaussmeter or demagnetization curve?

Demagnetization curve is more accurate for AlNiCo magnetism than Gaussmeter. Why Gaussmeter cannot accurately measure AlNiCo magnetism? Demagnetization field effect:AlNiCo magnets have high coercivity and low remanence, so they are easily affected by the demagnetization field during measurement. This causes the Gaussmeter to underestimate the actual magnetic field strength. Anisotropy:AlNiCo magnets are highly anisotropic, which […]

The Application of Magnets in Welding Machinery

Magnets play a crucial role in welding machinery, offering a range of applications that enhance efficiency, accuracy, and overall welding quality. Here’s how magnets are utilized in welding processes: Workpiece Fixation: Magnets are widely used to secure metal workpieces, especially ferromagnetic materials like steel. Magnetic clamps or magnetic welding tables provide quick and stable fixation, […]

Introduction to the Radiant Ring

A radiant ring is a special type of circular permanent magnet that is magnetized radially along the circumference. What is Radiant Ring? Features Structural Advantage: As an integral magnetic ring, it is easier to control the dimensional accuracy than the traditional spliced magnetic ring. The assembly process is more simplified without the need for a […]

Design and working principle of activation reed switch

Activation reed switch is the operation or process of causing the reed contacts inside the reed switch to change from an open state to a closed state, thereby completing the circuit. A reed switch, also known as a magnetic reed switch, is an electrical switch controlled by an external magnetic field. What is the working […]

Neodymium Magnets are Used in Aquarium and Saltwater

Neodymium magnets, also known as rare-earth magnets, are indeed used in aquariums and saltwater setups for a variety of purposes. Their strong magnetic properties make them useful in several applications within the hobby, especially in environments where traditional suction cups or adhesives may not be effective due to the harsh conditions. Here are some common […]

Will Smco Magnets Replace Neodymium Magnets in the Future?

In the future, it is unlikely that samarium cobalt magnets will completely replace neodymium iron boron magnets. The two will play their respective advantages in different fields for the following reasons: Performance NdFeB magnets: Known as the “king of magnets”, the magnetic strength is stronger than that of samarium cobalt magnets. The magnetic strength of […]

permanent magnet materials and application selection in Hall sensors

Hall sensors are widely used in position detection, speed measurement, current sensing and other fields. Their working principle is based on the Hall effect, and permanent magnets are used to provide a stable magnetic field source. Different permanent magnet materials are suitable for different application scenarios, so choosing the right permanent magnet is an important […]

Performance advantages of samarium cobalt magnets

Samarium cobalt (SmCo) magnets are high-performance rare-earth magnets known for their excellent magnetic properties and durability. Below are the key performance advantages of SmCo magnets: 1. High Magnetic Strength SmCo magnets exhibit a high energy density (up to 32 MGOe for Sm2Co17 grade). While slightly lower in magnetic strength than neodymium magnets (NdFeB), SmCo magnets […]
