Forma de bloque de imán de ferrita (Ferritebl01).

Grade Available: Y10T, Y20, Y25, Y30, Y30BH, Y35, Y40, etc(China Standard)C1, C5, C8, C11, etc. (USA. Standard)

Material: Fe2O3 + BaO or SrO, etc. Big block mainly made of anisotropic material; Small blocks can be made of isotropic materialDimension Describe: Length x Width x Height, Tolerance, Edge Degree, etc. Applications: Big blocks: Widely used in motors, cleaning machines, medical equipmentSmall blocks: Widely used in toys, decorations

Key Benefits

Inexpensive at medium to low magnetic strength.
Can be magnetized with multiple poles on one or both pole surfaces.
High coercive force.
Working temperature is up to 4500C.
Good resistance to demagnetization.
Does not rust, no surface treatment required.

Key Challenge

Very hard and brittle
Limited to simple size
Expensive mold charge
Properties degrade linearly with temperature, at 3500F, about 75% of room temperature magnetization is retained, and at 5500F, about 50% is retained

Quick Facts

Density: 4.6~5.0g/cm3
Saturation magnetizing field required: About 10KOe
Manufacture method: Dry press and wet press. The dry process is used for isotropic and anisotropic material, and the wet method applies only to the production of anisotropic material.
Shape available: Blocks, bars, discs, rings, arc segments, etc.
Grade available: C1 to C11, Br from 230MT to 430MT

Applications

Motors, Magnetic Couplings, Sensors, Loudspeakers, Magnet holding systems, Magnetic therapy, and Toys.
