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 300ºC, 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.

*1
Q) Are you a Magnet factory or trading company?
A) We are one of the leading magnet manufactures in Dongguan, welcome to visit our factory.
*2
Q) Does the magnet quality guarenteed?
A) Yes, we can guarentee the magnets we ship to you is of 100% with good quality as you order, if there is any product quality problem or products broken during shipping, we will bear 100% responsibility for you, you can ask for for related refund or replacement.
*3
Q) How long does it take for production and shipping duration?
A) For regular magnet orders, it would take 7-10working days or so, for customized items, it would take 25-35working days or so. Besides, the fastest production time is 3working days for the urgent orders.
*4
Q) How does the magnet grade and magnet dimensions(L x W x H) affects the Gauss Level of magnets?
A) Same magnet size, higher grade with higher gauss;
Same magnet grade, same surface area, the thicker, the higher gauss;
Same magnet grade, same thickness, larger surface area with lower gauss;
*5
Q) What does pulling force mean?
A) Pulling force is a measure of magnetic strength. It is the amount of force required to remove a magnet parallel to a solid magnetic surface, such as a steel plate.
*6
Q) If I stick two neodymium magnets together, does their strength double?
A) No. It will a little smaller. For example, two magnets rated with a individual pulling force of 50 lbs will have a combined pulling force of 90 lbs when stick together.
*7
Q) Do neodymium magnets lose strength over time?
A) They do not naturally lose any strength and will keep the strength permanently in the normal conditions, unless meet the high temperature over 80 degrees Celsius(ºC), and then will lose the strength gradually.
