Samarium Cobalt (SmCo) Cylinder Magnet - 4mm x 5mm

Engineered for performance in demanding environments, this Samarium Cobalt (SmCo) cylinder magnet combines compact size with exceptional thermal stability and corrosion resistance. With a 4mm diameter and 5mm height, this precision-made magnet is ideal for applications where reliability under extreme conditions is critical.

Manufactured from high-grade S280 Samarium Cobalt, this rare earth magnet offers consistent magnetic strength and excellent resistance to demagnetisation, even at elevated temperatures. Unlike neodymium magnets, SmCo magnets maintain their magnetic properties in high-heat environments, making them a preferred choice for specialist engineering and industrial use.

This magnet is identified by AMF Part Number 39080 and delivers a theoretical pull force of approximately 0.476kg (1.05lb), making it suitable for small-scale holding, positioning, and precision alignment tasks.

Why Choose Samarium Cobalt? Samarium Cobalt magnets are known for their excellent temperature stability, strong resistance to corrosion, and long-term magnetic reliability. They are particularly well-suited for environments involving heat, moisture, or chemically aggressive conditions where other magnet types may degrade.

Important Notes SmCo magnets are brittle and should be handled with care to avoid chipping or cracking

Pull force is measured under ideal conditions (direct contact with thick mild steel); actual performance may vary depending on application
