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.

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.
1. How to place order?
Re: PO from customer or PI from us
2. Any samples available?
Re: Samples are available. For our stock items, you only need to pay freight for few pcs. If we do not have stock items, then will need to arrange production for samples.
3. How long can order be delivered?
Re: If we have ready stock material, delivery could be 1-2 weeks, otherwise will be 2-3 weeks or so. Production time also depends on order quantity.
4. Is MOQ available for order?
Re: There will be no limit for order quantity, but price will depend on quantity: for small quantity, price will higher accordingly; if quantity is large, discounted prices will be offered accordingly as well.
5. Why customers choose us?
Re: 20 years' manufacturing experience; 8th Year Alibaba Gold Supplier; Regular customers from Europe & North America & Australia etc.; competitive quality & price.
Dear customer, as you know, our products are customized. So in order to save your time, our quotation is based on your requests for magnet strength, size, coating, magnetization direction and quantity. If you could send us drawingwhich shows the information in need, that will be much better for quote. :-p
