Alnico Magnet

Alnico Magnets (Al-Ni-Co, from Aluminum, Nickel, Cobalt) are renowned for their exceptional magnetic stability at high temperatures and superior resistance to corrosion. As a leading magnet manufacturer, we provide premium Alnico magnets that deliver reliable, long-lasting performance in the most demanding environments where other magnets may fail.

Core Advantages

1. Unmatched High-Temperature Performance: Our Alnico magnets maintain stable magnetic properties at continuous operating temperatures up to 500°C (932°F), making them the ideal choice for applications involving significant heat.

2. Exceptional Magnetic Stability & Low Decay: They exhibit extremely low magnetic flux loss over time and high resistance to demagnetization, ensuring consistent performance and precision throughout the product's lifespan.

3. Superior Corrosion Resistance: Unlike some rare-earth magnets, Alnico magnets do not require surface coating or plating for protection, as the alloy itself is highly resistant to oxidation and corrosion, simplifying design and reducing cost.

Key Features

• Material Versatility & Customization: We supply Alnico magnets tailored to meet specific operational needs. The magnetic properties, including strength (Br), coercivity (Hc), and temperature tolerance, can be optimized during our manufacturing process to achieve the ideal balance for your unique application requirements.

• Complex Shape Capability: Through specialized casting or sintering processes, they can be manufactured into complex shapes (e.g., horseshoes, rods, discs) that are difficult to achieve with other permanent magnet materials.

• Durable & Robust: The alloy is less brittle than rare-earth magnets, offering good mechanical durability for handling and assembly.

Typical Application 

• Industrial & Automotive: Widely used in electric motors, sensors, gauges, meters, and holding devices exposed to high temperatures.

• Aerospace & Defense: Critical in traveling wave tubes, radar equipment, and aerospace instrumentation requiring reliability under extreme conditions.

• Professional & Consumer Electronics: The classic choice for high-fidelity loudspeakers, microphone assemblies, and guitar pickups due to their warm tonal quality and stability.

• Research & Scientific Equipment: Employed in analytical instruments, particle focusing devices, and other precision laboratory equipment.
