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…
Overview of Magnetic Holding Systems Magnetic holding systems use magnetic force to hold, retain, mount, position, suspend, or secure parts in products or mechanical structures. They are not limited to one specific magnet type or one standard product category. Some magnetic holding systems are as simple as single magnets used to hold covers in place,…
Overview of Salt Spray Test Salt spray test, also called salt fog test, exposes samples to a controlled corrosive atmosphere inside a test chamber. In a neutral salt spray test, a sodium chloride solution is atomized into fine mist and continuously sprayed under controlled temperature and humidity conditions. The purpose of the test is to…
Magnetic holding under vibration is different from static magnetic holding in ideal test conditions. Holding magnets may show high pull force on clean, flat, and thick steel plates, but real industrial environments often involve vibration, impact, coatings, corrosion, uneven contact, air gaps, and changing load directions. For this reason, magnetic holding under vibration should not…
Magnetic holding force is one of the most important reference values when selecting magnetic bases, rubber coated magnets, and other magnetic holding products. However, this value should not be treated as the guaranteed working load in every application. In real working conditions, magnetic holding force can change significantly. The actual performance depends on the steel…
Overview of Magnetic Shielding Magnetic shielding is a method used to control how magnetic fields spread in space. In many cases, it does not completely block a magnetic field like a wall blocks light. Instead, it provides an easier path for magnetic flux, guiding part of the magnetic field through a suitable material and reducing…
Overview of Air Gap in Magnetic Holding Systems Air gap is a basic but often underestimated factor in magnetic systems. It refers to the non-magnetic distance or layer between magnets and the objects they need to attract, hold, sense, drive, or interact with. In practical use, this gap is not always only air. It may…
