SM-047899 Painted Red AlNiCo U-Shaped Horseshoe Magnets 59×59×15mm with Φ9mm Hole

·  Premium AlNiCo Alloy with Stable Magnetic Performance: Engineered from high-grade sintered AlNiCo, these U-shaped magnets deliver consistent magnetic flux density, high coercivity, and minimal magnetic drift over time. The horseshoe geometry concentrates magnetic flux between the two poles, maximizing holding force and creating a clear, detectable magnetic circuit ideal for teaching magnetism, conducting experiments, and light-duty metal holding tasks.

·  Bright Red Enamel Paint for Visibility & Protection: The glossy red enamel coating offers dual benefits: it provides robust corrosion resistance, shielding the AlNiCo alloy from oxidation, scratches, and environmental wear, while the vivid red color ensures clear visual identification, making these magnets easy to locate and suitable for safety-critical educational or workshop use. The smooth, durable paint finish is resistant to chipping and easy to clean, maintaining its appearance even with frequent handling.

·  Precision 45×30×30mm U-Shaped Design with Φ5mm Hole: The compact horseshoe profile is precision-machined to strict dimensional tolerances, with a central Φ5mm mounting hole for secure attachment to stands, fixtures, or lab equipment. This design balances portability and holding power, making the magnets suitable for handheld use as demonstration tools or mounted applications in educational labs and hobby projects.

·  Superior Thermal & Environmental Stability: AlNiCo’s inherent thermal stability ensures these magnets maintain consistent magnetic performance across a wide temperature range, with minimal magnetic loss even at elevated operating temperatures. The combination of the AlNiCo alloy and red enamel coating provides excellent resistance to humidity, dust, and mild chemical exposure, ensuring reliable long-term performance in diverse indoor environments.

·  High Mechanical Durability & Impact Resistance: The dense sintered AlNiCo structure offers excellent mechanical strength, while the red enamel paint adds a protective layer that resists chipping and cracking during handling or accidental impacts. This durability makes these magnets suitable for frequent use in educational labs, workshops, and hobbyist settings where magnets may be dropped or handled roughly.

These red-painted AlNiCo U-shaped horseshoe magnets, precision-engineered at 45×30×30mm with a Φ5mm mounting hole, are compact, high-performance aluminum-nickel-cobalt permanent magnets designed for educational demonstrations, light-duty industrial holding, and hobbyist applications. Crafted from premium sintered AlNiCo alloy, they deliver strong, concentrated magnetic fields, excellent coercivity, and long-term stability, even with repeated use and temperature fluctuations. The classic horseshoe design maximizes magnetic flux between the two poles, creating a powerful, focused holding force, while the glossy red enamel paint provides clear visual identification, enhanced corrosion resistance, and a durable, easy-to-clean surface. Unlike uncoated magnets, the red paint layer protects the AlNiCo alloy from oxidation, scratches, and environmental wear, extending service life in classrooms, workshops, and lab environments. Each magnet undergoes rigorous quality control, including dimensional verification, magnetic performance testing, and coating inspection, ensuring tight tolerances, uniform magnetic properties, and reliable fit for both educational and light industrial use.
