SM-0478101 Red-Painted AlNiCo Cylinder Magnets D45×25mm with Mounting Hole, High-Temperature Permanent Magnets for Education & Industrial Applications

·  Premium AlNiCo with Superior Thermal Stability: Engineered from high-grade sintered AlNiCo, these magnets maintain consistent magnetic performance across a wide temperature range, with minimal magnetic loss even at continuous operating temperatures up to 500°C. This makes them ideal for high-temperature environments where neodymium or ferrite magnets would suffer irreversible demagnetization, ensuring reliable performance in industrial furnaces, educational labs, and high-temperature processing equipment.

·  Bright Red Enamel Paint for Protection & Visibility: The glossy red enamel coating provides dual benefits: it enhances corrosion resistance, shielding the AlNiCo  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 resists chipping and is easy to clean, maintaining its appearance even with frequent handling.

·  Precision D45×25mm Cylindrical Design with Mounting Hole: The compact, round profile is precision-machined to strict dimensional tolerances, with a central hole for secure attachment to stands, fixtures, or lab equipment. The cylindrical shape ensures uniform magnetic field distribution, making these magnets ideal for educational demonstrations of magnetic fields, light-duty metal holding tasks, and magnetic testing applications.

·  Consistent Magnetic Performance & Low Temperature Drift: Sintered AlNiCo exhibits a very low temperature coefficient of remanence, meaning its magnetic flux density changes minimally with temperature fluctuations. This stability is critical for applications like educational experiments and industrial holding tasks, where consistent magnetic output is required for reliable results.

·  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 classrooms, workshops, and industrial environments where magnets may be dropped or handled roughly.

These red-painted AlNiCo cylinder magnets, precision-engineered at D45×25mm with a central mounting hole, are premium aluminum-nickel-cobalt permanent magnets designed for educational demonstrations, industrial holding tasks, and high-temperature environments. Crafted from high-grade sintered AlNiCo , they deliver strong, stable magnetic flux density, excellent coercivity, and exceptional long-term stability, even under extreme temperature fluctuations and repeated use. The cylindrical form factor provides uniform magnetic field distribution, while the glossy red enamel paint offers clear visual identification, enhanced corrosion resistance, and a durable, easy-to-clean surface. The central mounting hole allows for secure attachment to stands or equipment, making these magnets versatile for both handheld and fixed applications. Each magnet undergoes rigorous quality control, including dimensional verification, magnetic performance testing, and coating inspection, ensuring tight tolerances, uniform properties, and reliable performance in diverse settings.
