Sm2co17 Samarium Cobalt Magnet

Sm2co17 Samarium Cobalt Magnet is a rare earth permanent magnet material composed of samarium (Sm) and cobalt (Co). Its crystal structure is hexagonal close-packed, an alloy consisting of 2 samarium atoms and 17 cobalt atoms. The magnet is formed by precise composition ratio and appropriate heat treatment process, usually showing dark gray to black metallic luster.

High density and structural stability
The density of Sm2Co17 samarium cobalt magnet is 8.4 g/cm³, which reflects its high density characteristics. It not only means that the material is of high quality, but also the physical basis of its strong magnetic properties. The high-density Sm2Co17 magnet has a tighter atomic arrangement, which makes the magnetic field more concentrated, thereby enhancing the magnetism of the magnet. In addition, when subjected to external forces or temperature changes, materials with higher density can better maintain the stability of the internal structure and avoid the degradation of magnetic properties due to internal stress changes.
 

High Curie temperature
The Curie temperature of Sm2Co17 magnet is 1100K (827℃). This high-temperature performance enables it to maintain stable magnetism in high-temperature environments. The Curie temperature refers to the temperature at which a material loses its permanent magnetism. For permanent magnetic materials, the higher this temperature, the stronger the material's ability to retain magnetism at high temperatures. Due to its unique crystal structure and composition configuration, samarium cobalt alloy exhibits a Curie temperature far higher than that of conventional magnet materials, allowing Sm2Co17 to still work stably at high temperatures.
 

Excellent resistivity and corrosion resistance
The resistivity of Sm2Co17 magnet is 8~9×10⁻⁵ Ω·cm, which indicates that it has relatively low conductivity, making the material more resistant to current interference. In addition, lower conductivity is usually associated with higher corrosion resistance, which can effectively resist the erosion of moisture or corrosive substances in the environment, thereby ensuring that it can maintain stable performance in various harsh environments.
 

Strong bending strength
The bending strength of Sm2Co17 magnet is between 130-150 MPa, which means that it can withstand a large degree of stress without cracking or breaking when it is bent by external force. Bending strength is an important indicator to measure the material's ability to resist deformation under bending load. The high bending strength of Sm2Co17 magnet makes it more reliable in application,

 

Application:

These magnets are used for many industries, Let is check How they are used in Fireplaces?

• Fireplace Door Closures:

  Sm2Co17 Ni-coated magnets are frequently used to secure the doors of wood-burning or gas fireplaces. Their strong magnetic pull ensures a tight seal, preventing heat loss and making the fireplace more energy-efficient. The corrosion resistance provided by the nickel coating ensures that the magnet will perform optimally, even when exposed to heat and smoke.

• Magnetic Ash Collection:

  The magnetic properties of Sm2Co17 magnets can be leveraged to collect metal debris and ash particles from the fireplace. The nickel coating ensures that the magnets remain unaffected by soot or moisture, providing consistent performance over time.

• Securing Fireplace Grills or Screens:

 These magnets can also be used to hold fireplace grills or protective screens in place. The strong magnetic force keeps these components securely attached while allowing for easy removal and adjustment when necessary.

• Temperature Control Systems:

 Some advanced fireplace systems incorporate Sm2Co17 magnets in their temperature control mechanisms, using the magnets' stability under heat to regulate airflow or adjust the intensity of the flame.
