Samarium Cobalt Arc Magnet is an ideal solution to high-temperature applications and offer

 Samarium Cobalt Arc Magnet has good corrosion resistance. Sm1Co5 does not rust because it does not contain iron.

However, Sm2Co17 should be coated with a protective coating in very wet  conditions to minimize the risk of surface corrosion. However, Sm1Co5 does not rust because it does not contain iron.

 Samarium Cobalt Arc Magnets are expensive and subject to price fluctuations (cobalt is market price sensitive)

 Samarium Cobalt Arc Magnets   exhibit magnetic anisotropy, meaning they can only be magnetized in the axis of their magnetic orientation. This is done by aligning the crystal structure of the material during the manufacturing process.

 Samarium Cobalt Arc Magnets known for their high magnetic strength, excellent temperature stability, and resistance to demagnetization. Here are the typical technical parameters for powerful SmCo arc magnets:

1. Material Composition: – Samarium (Sm): 35% – Cobalt (Co): 60% – Other elements such as Iron (Fe), Copper (Cu), Zirconium (Zr), and Hafnium (Hf) may be included to enhance specific properties. 2. Magnetic Properties: – Residual Induction (Br): 9,500 – 11,000 Gauss (0.95 – 1.1 Tesla) – Coercive Force (Hc): 9,000 – 10,500 Oersteds (716 – 835 kA/m) – Intrinsic Coercive Force (Hci): 15,000 – 30,000 Oersteds (1,194 – 2,388 kA/m) – Energy Product (BHmax): 22 – 30 MGOe (175 – 239 kJ/m³) 3. Physical Properties: – Density: 8.2 – 8.4 g/cm³ – Electrical Resistivity: 0.8 – 0.9 μΩ·m – Thermal Conductivity: 10 – 15 W/(m·K) 4. Temperature Stability: – **Maximum Operating Temperature**: 250 – 350°C (482 – 662°F), depending on the specific grade – **Curie Temperature**: 700 – 850°C (1,292 – 1,562°F) – SmCo magnets maintain high magnetic stability over a wide temperature range and are less prone to thermal demagnetization compared to other types of permanent magnets. 5. Mechanical Properties: – Hardness: Vickers 500 – 600 HV – Compressive Strength: 800 – 1,000 MPa – Tensile Strength: Low, brittle material; care must be taken to avoid mechanical stress 6. Corrosion Resistance: – SmCo magnets have excellent corrosion resistance and typically do not require coating or plating for protection in most environments. 7. Tolerance: – Typical machining tolerance for SmCo magnets is ±0.05mm, though this can vary based on specific manufacturing capabilities and requirements.
