Key Advantages
Excellent temperature stability
Strong corrosion resistance
The maximum working temperature is up to 500°c
Excellent capacity
High density and magnetic properties
Shorter production lead time
Temperature factor of Br is the smallest among all the permanent magnets
Cast Alnico magnets can be produced in relatively complex shapes
Tooling for cast Alnico magnets is relatively low, since sand molds are generally used for the casting process.

Zhu Zhou Summit New MAterials Co. Ltd was founded in 2009, as a professional manufacturer and exporter, We are specialized in producing of rare earth magnet with the capacity of 1000 ton/year, including the grade of sintetred NdFeB magnet such as N52 N50M N48H N45SH N40UH N38EH N33AH. Great block magnets of N45H (6"X4"X2") for magnetic suspension, Big ring magnets N42M (OD100 OD120 OD150 OD160 OD200) for magnetic separator, All kinds of complicated shape of arc magnets for automotive motor and wind power generator are competitive.
Our aim is to provide all kinds of magnetic solutions for customers. Our senior engineer provides Halbach circuit magnetic design, High speed DC motor magnetic problem and lamination solutions.
All kinds of magnetic assemblings is possible in our workshop with our special tool and methods.
Now we can provide Halbach ring magnets with 0.8T-1.4T, magnetic polars for magnetic suspension parts, great magnetic brake and couplings, rotor magnets for DC motor, RMI magnets, 1.5T magnetic pulley, 1.25T magnetic grate bar and so on.
We can promptly produce loudspeaker unit and stamping lamination stator, rotor according to customer' design.
Special surface coating of Neodymium magnets is very important, we can provide magnets with parylene coating, Electroless Nickel, epoxy coating!
Our purpose " Honesty, Professional, Mutual Benefit "
