Comparative Advantages
Pot magnet 🆚 Countersunk magnet
Compared to square countersunk neodymium iron boron magnets, which lack a protective steel shell and have dispersed magnetic force, making them more prone to breakage or cracking, rectangular steel case pot magnets have significant advantages: their steel shell concentrates the magnetic force, resulting in stronger attraction; the protective shell enhances impact resistance and prevents damage to the magnets.
Epoxy coated pot magnet 🆚 Nickel coated pot magnet
Nickel-plated pot magnets have a glossy appearance, but their corrosion resistance is limited, and they are prone to rusting in heavily humid or salty environments.
Epoxy coated mounting magnets, on the other hand, offer superior moisture and salt resistance, are durable, and are available in black and white epoxy coatings for a more understated or harmonious look.
Rectangular pot magnet 🆚 Round pot magnet
Compared to round pot magnets, rectangular pot magnets offer a larger contact area.
While round pot magnets have strong central attraction, their contact area on long metal surfaces is limited. The slender shape of long rectangular pot magnets is better suited for I-beams, square tubes, and equipment frames, and different aspect ratios can be customized, offering greater flexibility.
Therefore, the rectangular design is a superior choice when higher stability or compatibility with long workpieces is required.
