SM-047898 Sintered AlNiCo Square Block Magnets 59×59×15mm with Φ9mm Mounting Hole

Premium AlNiCo Alloy with Unmatched Thermal Stability: Engineered from high-grade sintered AlNiCo, these magnets maintain stable magnetic performance across an extremely wide temperature range, with a Curie temperature exceeding 850°C and minimal magnetic loss 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 consistent performance in industrial furnaces, aerospace systems, and high-temperature processing equipment.

Natural Corrosion Resistance (Uncoated Construction): AlNiCo’s metallic composition offers inherent resistance to oxidation, rust, and environmental wear, eliminating the need for electroplating or protective coatings. This uncoated design preserves the magnet’s structural integrity and magnetic properties over decades of use, reducing maintenance costs and ensuring long-term reliability in humid, industrial, or outdoor conditions where coated magnets may degrade or flake over time.

Precision 59×59×15mm Block with Central Φ9mm Hole: The square block geometry with a precisely machined Φ9mm central hole is optimized for secure mounting with standard fasteners, enabling flush, aligned installation in fixtures, jigs, and machinery. Tight dimensional tolerances ensure perfect fit and alignment, while the central hole adds structural flexibility, allowing for custom integration into both static and dynamic industrial assemblies without compromising magnetic performance.

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 precision applications like industrial sensors, flow meters, and aerospace navigation systems, where consistent magnetic output is required for accurate, repeatable measurements, even in variable operating conditions.

High Mechanical Durability & Structural Integrity: AlNiCo’s dense, sintered structure provides excellent mechanical strength and low brittleness compared to ceramic or rare-earth magnets, making these block magnets resistant to chipping, cracking, and damage during installation, handling, or high-vibration operation. Their robust composition also ensures structural stability under heavy loads, making them suitable for use in industrial holding fixtures and magnetic clamping systems.

These sintered AlNiCo square block magnets, precision-engineered to 59×59×15mm with a central Φ9mm through-hole, are premium aluminum-nickel-cobalt permanent magnets purpose-built for heavy-duty industrial, high-temperature, and precision engineering applications. Crafted from high-grade AlNiCo alloy, they deliver exceptional magnetic flux density, consistent coercivity, and outstanding long-term stability, even under extreme temperature fluctuations, high vibration, and prolonged operational cycles. The custom square profile with a precisely machined central hole is optimized for secure, aligned mounting, enabling seamless integration into fixtures, machinery, and specialized assemblies while preserving uniform magnetic performance. Unlike rare-earth magnets that rely on protective coatings, AlNiCo’s inherent metallic composition provides natural corrosion resistance, eliminating the risk of coating degradation in humid, industrial, or mildly corrosive environments. Each magnet undergoes rigorous quality control, including dimensional verification, magnetic performance testing, and surface inspection, ensuring tight tolerances, uniform properties, and reliable fit in mass-produced systems, making them ideal for high-temperature sensors, aerospace components, industrial automation equipment, and magnetic holding applications.
