Shuttering magnets are widely used to secure side forms, block-outs and other formwork components to steel casting tables. Compared with drilling, welding or permanently fixing the formwork, a magnetic shuttering system allows the production layout to be changed more quickly between precast concrete elements. The principle is straightforward: place the shuttering magnet on the steel…
Limits of High-Temperature Pot Magnets The temperature limits of high-temperature pot magnets are not determined by the permanent magnet materials alone. Pot magnets are complete magnetic assemblies that may include permanent magnets, steel pots, pole pieces, threaded components, spacers, adhesives, coatings, and filling materials. Each component may respond differently to elevated temperatures. Permanent magnets may…
Magnetic separator strength is often reduced to a single number: 8,000 Gauss, 10,000 Gauss or 12,000 Gauss. These figures are useful, but they do not provide a complete picture of how a separator will perform in a production line. Two magnetic rods can show similar surface Gauss readings and still behave differently when removing iron…
Overview of HRE-Free Magnets HRE-free magnets generally refer to Neodymium (NdFeB) magnets designed to achieve the required coercivity without heavy rare earth elements, particularly Dysprosium (Dy) and Terbium (Tb). These elements have traditionally been used in certain high-coercivity grades to improve resistance to irreversible demagnetization, especially at elevated temperatures. HRE-free technology was originally developed to…
Overview of Magnetic Bases Magnetic bases combine magnetic holding force with a practical mounting interface. Instead of functioning as standalone magnets, they are designed to support, position, or attach other objects to ferromagnetic surfaces. The mounted object may be a light, sign, sensor, camera, tool, bracket, enclosure, guard, or another accessory. Depending on the design, the…
A magnetic separator has a straightforward purpose: remove ferrous contamination from a product or process stream. Selecting the right separator, however, is rarely as simple as choosing the model with the highest advertised Gauss value. A separator that works well with dry, free-flowing granules may block when used with a sticky powder. A magnetic grate…
Can Magnets Be Shipped by Air? Yes. Magnets can be shipped by air, but they cannot always be treated like ordinary metal parts. Many buyers need to ship magnets by air from China for samples, urgent production parts, replacement components, and time-sensitive projects. The key issue is not only the magnet material itself, but the…
Overview of Magnets for Offshore Applications Magnets for offshore applications are used in environments where salt spray, humidity, vibration, ultraviolet exposure, outdoor weathering, and difficult maintenance conditions must be considered together. These applications may include offshore wind turbines, oil and gas platforms, marine equipment, vessels, ports, and coastal industrial facilities. In these environments, magnets are…
What Happens When Magnets Meet Steel? Permanent magnets and steel are often used together in holding devices, motor structures, magnetic sensors, steel-backed components, and many other engineered products. In simple terms, permanent magnets can attract steel because many steels can be magnetized by the magnetic field. However, steel parts are not just passive objects being…
