Wholesale Block Permanent Samarium Cobalt Magnets

Product Description

WHY CHOOSE US:
Zhijiang magnetics is a company specialized in manufacturing Alnico Magnets (Alnico 2 to Alnico 9) and Samarium Cobalt Magnets (SmCo 5 and Sm2Co17), we are professional, with more than 18 years experiences for manufacturer and export.

Samarium Cobalt Magnet Description
Samarium Cobalt Magnet is mainly made of Cobalt,Samarium and other rare earth elements. Its advantage is the maximum operating temperature up to 300ºC and its good corrosion and oxidation resistance. Samarium Cobalt Magnets, therefore do not need to be coated. It is widely used in motors, meters, sensors, detectors, engine, rada and other high-tech fields.

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.Or according to your requirement to packing.
+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.

Tolerance
General tolerances:cutting surface+/-0.05- +/-0.2mm ground surface +/-0.01- +/-0.1mm,or according to your request.

Sample
In general, SmCo samples were around 15 days, Alnico samples were 25 days, and Ndfeb was the same as SmCo samples.
