Smco5 Sm2co17 Samarium Cobalt SmCo Magnetic Magnet Blocks Custom
Size
Description:
A samarium–cobalt (SmCo) magnet, a type of rare earth
magnet, is a strong permanent
magnet made of two basic elements samarium and cobalt.They were developed in the early 1960s based on work done by Karl
Strnat and Alden Ray at Wright-Patterson Air Force Base and the University of Dayton, respectively. In particular, Strnat and Ray developed the first
formulation of SmCo5.They are generally ranked similarly in strength to neodymium
magnets, but have higher temperature ratings and higher coercivity.
Extremely resistant to demagnetization
Good temperature stability.
Expensive and subject to price fluctuations (cobalt is market price
sensitive)
Samarium–cobalt magnets have a strong resistance to corrosion and
oxidation resistance, usually do not need to be coated can be
widely used in high temperature and poor working conditions.
Series
Samarium–cobalt magnets are available in two "series", namely SmCo5 magnets and Sm2Co17 magnets.
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, 1:15 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.

Packing:
As the magnets have strong attraction and we will use the spacer to
apart the magnets each other in case people will be hurt when take
it out. Then, they will be packed in a white box of pieces each,
several boxes to a carton.
+By Air: If the goods will be shipped by air, all the magnetic
should be degaussed and we will use Iron sheet to shield.
+By Sea: If the goods are will be shipped by sea, we will place a
pallet on the bottom of cartons.
Shipping:
Express (TNT, DHL, FedEx, UPS, etc), Air, Ocean.
A: The weight is under 40Kgs, we recommend to send them in
shielding boxes to you by Express.
B: The weight is between 40Kgs-100Kgs, it can be sent by Express or
Air.
C: The weight is over 100Kgs, we recommend to send them by Ocean.
