Since being founded in 2001, Ningbo LG Magnetics Manufacturing Co., Ltd. has been specialized in R&D and production of sintered 1:5, 2:17 Samarium Cobalt permanent magnets, sintered Ndfeb, Ferrite magnet and assemblies. Through 12 years' great-leap-forward development, now Ningbo LG is a company, which covers an area of 12000 square meters including an area of 5000sm of factory building, with an annual production capacity of 1200 tons of SmCo and 1000 tons of NdFeB products. It brought in advanced producing, machining and testing equipments and the fixed asset values more than RMB 32 million.
In past seven years, Ningbo LG had been taking the independent and collaborative innovation as the strategy of technology innovation. LG strengthened the ability of independent innovation by increasing the inputs on technical innovation, bringing in high level technology talents and combining the market demands. What's more, through the cooperation with the research institutions such as The Chinese Academy of Sciences, Ningbo Materials Technology and Engineering Institute, etc, LG improved the ability of researching and developing high-end products.
Ceramic, also known as ferrite,
magnets are made of a composite of iron oxide and barium carbonate (BaCo3) or
strontium carbonate (SrCO3).
Widely available since the 1950's,
this material is commonly available and at a lower cost than other types of
materials used in permanet magnets.Ceramic magnets are made using
pressing and sintering. Sintered magents are a type of ceramic composed of the
compressed powder of the alloy material being used.Sintering involves the compaction of
fine alloy powder in a die and then fusing the powder into a solid material with
heat. While the sintered
magets are solid ,their physical properties are more similar to a seramic and
are easily broken and chipped.
Ceramic magents are brittle and hard
generally requiriing diamond wheels to grind and shape.
These magnets come in a number of
different grades. Ceramic-1 is an isotropic grade with equal magnetic properties
in all directions.
Ceramic grades 5 and 8 are
anisotropic grades. Ansotropic magents are magnetized in the direction of
pressing.The anisotropic
method delivers the highest energy product among ceramic magnets at values up to
3.5 MGOe ( Mega Gauss Oersted). Ceramic magnets have a good
balance of magnetic strength,
resistance to demagnetizing and economy. They are the most wide used magents
today.
Beneficial characteristics of ceramic magnets include their low cost, high coercive force, resistance to corrosion, and high heat tolerance. Drawbacks include their low energy product or "strengh", low mechanical strengh, and the ferrite poweder on the surface of the material which can rub of and cause soiling.
1.Material: ferrites ,Strontium,etc.
2.Grade: Y25,Y30,Y30BH,etc.
3.Size: It will be different according to client's requirement;
4.Shape: Arc,Tile,Block,Bar,Ring,Cube, Rectangular or others.
5.Application:Widely used in ammeter,speaker,audio,phone,TV,dynamo,etc.
Advantage
1.Cheapest magnet material
2. Good anti-corrosion
performance, no surface treatment needed
3.Excellent temperature stability
4.Compact crystal
5.Could provide isotropic and
anisotrpic
Two
manufacturing Process
1.Dry process: By dry process, can produce isotropic & anisotropic
magnets;the tool can be changed and developed easily.
2.Wet
process: By wet process, only anisotropic magnets can be
produced;it is complicated to change the tool and the tooling charge is much
higher
Magnetization
1.Isotropic ferrite magnets are not oriented and can be magnetized
in any direction;
2.Anisotropic ferrite magnets are different, they are all oriented in the manufacturing
direction, and should be magnetized in the direction of orientation.
Attributes
1. Least expensive material
compared to alnico and rare earth magnets
2. High intrinsic coercive
force
3. Available in simple shapes only due to manufacturing process
4. Lower service temperature than alnico, greater than rare earth
5. Finishing requires diamond cutting or grinding wheel
6. Lower energy
product than alnico and rare earth magnets
7. Most common grades of
ceramic are 1, 5 and 8 (1-8 possible)
8. Grade 8 is the strongest ceramic
material available
9. Tooling can be expensive
