Alnico Disc Magnet 10x2mm

Alnico Disc Magnet 10×2mm is a thin cylindrical permanent magnet manufactured with a 10 mm diameter and 2 mm thickness for compact magnetic field applications in sensing and small mechanical assemblies.
Produced from Alnico alloy (aluminum, nickel, cobalt, iron) through casting and precision machining processes, providing stable magnetic output under varying operating temperatures.
The disc structure is typically magnetized through thickness, generating a uniform magnetic field between the two flat circular surfaces for reliable magnetic interaction.

Product Advantages

The Alnico Disc Magnet 10×2mm uses a cast AlNiCo alloy structure (Al–Ni–Co–Fe), which provides stable magnetic output under temperature variation conditions commonly found in sensors and compact electronic assemblies.
The 2mm thickness design enables short magnetic path length, allowing fast magnetic response in proximity detection and switch triggering systems with tight installation spacing.
Precision grinding on both flat surfaces ensures consistent pole flatness, which improves air-gap stability and reduces signal fluctuation in sensor and positioning applications.
The material maintains magnetic stability under moderate thermal conditions, making it suitable for instrumentation systems where temperature fluctuation can affect magnetic consistency.

Quality Control System

Dimensional inspection

Each Alnico Disc Magnet 10×2mm is measured for diameter and thickness to ensure precise fit in sensor housings, instrument assemblies, and compact mechanical structures, reducing alignment deviation during installation.

Magnetic performance testing

Magnetic flux and surface field strength are tested per batch to control consistency of magnetic output, ensuring stable switching response and signal reliability in sensing applications.

Surface & structural inspection

ach batch is checked for surface cracks, edge chipping, and machining defects, followed by sampling verification before shipment to ensure structural integrity and production consistency.
