Description
4mm × 20mm Alnico 5 Rod Magnet
This Al nico 5 rod magnet measures 4mm in diameter × 20mm in length and provides dependable magnetic performance with excellent temperature stability. Alnico 5 offers strong residual induction and good coercivity, making it well suited for sensors, pickups, experimental setups, and educational demonstrations where a compact but slightly stronger magnet is required.
Dimensions: 4 mm (Ø) × 20 mm (L)
Material/Grade: Alnico 5
Approx. Surface Gauss: ~1,000–1,200 G (at pole face)
Approx. Pull Strength: ~0.15 kg
Max Operating Temp: ~500 °C
Durable and resistant to demagnetisation, this rod magnet is ideal for precision applications requiring stable magnetism in high-temperature or demanding environments.
