2019 Samarium Cobalt SmCo5/Sm2Co17 SmCo Block/ Disk/ Ring/ Arc Magnet 

 

 

1.Material of strong smco magnet

Sintered SmCo Magnet, Samarium-Cobalt, 35% Sm, 60% Co with the balance being Fe & Cu

  

SmCo magnets for sale are divided into two types: SmCo5 and Sm2Co17. SmCo5 has a maximum energy (BH) max of 22MGOe.. Compared with 30MGOe(BHmax) of Sm2Co17, the composition of 2:17 magnets offers better anti-corrosion ability and is more stable at very high temperatures. The temperature environment is 250 ~350 . The above characteristics make SmCo the ideal material in applications like servo-motors, pump couplings, and sensors, particularly where the magnet is required to work at high temperature in a corrosive environment.

1:5 alloy material
1:5 offers 16 MGOe (energy product) to 22 MGOe and is made up of approximately 50% samarium and 50% cobalt. The 1:5 series has a maximum recommended operating temperature of 250°C. SmCo 1:5 magnets require lower field strengths than 2:17 materials to magnetize. In some instances, 1:5 material may be magnetized with multiple poles, provided that a magnetizing fixture is available.

 

2:17 alloy material
2:17 offers 24 MGOe to 32 MGOe and is composed of about 25% samarium, 5% copper, 18% iron, 2% hafnium or zirconium, with the remainder being cobalt. The 2:17 series of has a maximum operating temperature of 350°C. Special grades of 2:17 are available which can operate to even higher temperatures. SmCo 2:17 requires extremely high magnetizing fields, and multiple pole magnetization is not possible.  

 

2. Key Features of smco magnet

  Superior resistance to high temperature(max temperature reaches 350 degree centigrade)

   180degree centigrade, its maximum energy product BH and temperature stability are superior

      than NdFeB  magnet.

  Excellent resistance to corrosion, no coating is needed for the surface protecting.

  Reliable coercive force

  Environment and recycle friendly.

Packaging & Shipping

Packaging & Shipping:

Usually, shipping has 3 methods: 1. by Express(DHL, UPS, FEDEX, TNT, ARAMEX etc.); 2. by Air; 3. by Sea. Packaging method differs from shipping method, can also be customized as per clients' requirements.

1. Shipping by Express: Master carton will be lined with iron sheet cover so that the magnetisim can be shielded so as to be available for flight.

2. Shipping by Air: Packaging will be same as shipping by Express.

3. Shipping by Sea: Master carton will not be shielded covered but will be sturdily sealed & packed in order for better sea shipping.
