SmCo Is Also Named With SmCo Magnetic Steel, SmCo Permanent Magnet, SmCo Permanent Magnetic Iron And Rare-Earth Cobalt Permanent Magnet. It's A Kind Of Material Made From Raw Earth Metal Samarium And Cobalt And Produced By After A Serial Of Process Burdening,Melting,Milling,Pressing And Sintering .It's Also A High Performance, Low Temperature Coefficient Permanent Magnet With Its High Working Temperature&Mdash;350 Degree Centigrade. When Working Above 180 Degree Centigrade, Its Maximum Energy Product BH And Steady Temperature Are Superior Than NdFeB Magnetic Materials. It Need't To Be Coated Because It Is Difficult To Be Eroded And Oxidized. SmCo Magnet Is Widely Used In Space Probe,National Defense And Military ,Microwave Appliance,Communication,Medical Equipments,Motors, Instruments, Various Magnetism Spreading Devices,Sensor,Magnetic Processor,Magnetic Lifter And So On.

Beneficial Advices

(1)Sintered SmCo Permanent Magnetic Materials Have The Character Of Brittleness, Lacking Of The Ductility. So It Isn't Suitable For Using As Structural Part When Being Designed. The Physical Specifications Of SmCo(1:5) Is Better Than SmCo(2:17) Because SmCo(1:5) Is Easy To Machine While SmCo(2:17) Is More Brittle. SmCo Permanent Magnet Magnetized Must Be Picked Up Carefully During The Process Of Assembling, Avoiding Ironware To Prevent Absorbing Mutually And The Magnets Broke Off, Or Two Slices Of Magnetic Irons Cause Damage Resulted In Absorbing Together, Besides, It Will Even Cause Body-Hurt
(2)Sintered SmCo Permanent Magnetic Materials Would Make Some Slight Collision In The Process Of Producing, Packing And Delivering, So There May Be Have Some Visual Flaw Owing To A Bit Small Horn. However, It Wouldn't Damage Its Magnetic Specifications, Its Stability And Its Anti-Degenerated Magnetic Ability As Long As Its Flaw Doesn&Rsquo;T Affect Normal Construction Or Functions.
(3)Clients Who Require Non-Magnetized SmCo Permanent Magnet Must Be Acquaint With Self-Magnet Equipments For The Purpose Of Completely Satiate And Magnetize Our Products Or Codes.
(4)If The Designed Products Are In Sour Alkali Or Worse Applying Environments, Our Company May Provide Products Of Zn, Ni, Gold Or Wreath Oxygen Plated. We Feel Very Graceful For Your Applications. Welcome To Fax Or Make Email Consultation. We Are Pleased To Help You With All Problems Of The Techniques. We All Work Hard Trying To Provide You SmCo Permanent Magnetic Materials With Top-Quality And Low-Price.
