High Temperature SmCo Permanent Motor Magnet
SmCo is a high-capacity permanent magnet made from Sm, Co, Fe and other trace metal elements. Besides a max working temperature of 300º C, it has remarkable resistance against corrosion and oxidation. Hence, it may be used in aeronautic and space industries among others.

Attributes of Samarium Cobalt:

1. High resistance to demagnetization
2. High energy (magnetic strength is strong for its size)
3. Good temperature stability

Applications of Samarium Cobalt:

Computer disc drives, sensors, traveling wave tubes, linear actuators, satellite systems, motors where temporary stability is vital.

Machining and tolerances
We achieve dimensional size and tolerance by cutting or grinding with super abrasives. Samarium Cobalt (SmCo) cannot be ground with conventional drilling, turning or milling processes, and must be machined before they are magnetized. Additionally, large or complex assemblies are usually magnetized prior to assembly. Standard tolerances for Samarium Cobalt magnets are +/-. 05mm for ground dimensions. We stocks SmCo magnets in block, ring and disc form in a variety of sizes and grades, and we are fully equipped to produce the size and tolerance that you require.
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.
