SmCo magnets 

Sintering SmCo magnets are circularly made by strict powder metal technology and heat processing. This kind of magnet conveys samariam for 35%, cobalt for 60%, element Fe and Cu. Through altering proportioning of compositions and circulation of sintering and heating, we can make two materials_ 1: 5 and 2: 17. The difference lies in energy product, temperature coefficient and coercivity. The most common material, 2: 17, has better property and lower temperature coefficient, but it is more expensive and should be magnetized in high magnetic field. 

Americans invented SmCo5 and SmCo17 in 1965 and 1972. This invention drives a high wave to study and explore new permanent magnetism, and promote the development of the materical rapidly. This material is produced by powder metallurgy, and its specialty is its magnetic stability, temperature resistance, and excellent resistance of corrosion. Its max magnetic energy prduct is 15~30MGOe which is 3~5 times to AlNiCo magnets. Its intrinsic coercivity is over 25kOe, and its highest working temperature is 350 C. SmCo magnet is very suitable for manufacture the products with high-performance like magnetic motors and other applied products requiring high working temperature. 

Our adventures: 

1. Our Hydrogenated powdering can assure the powder uniformity and reduce the oxidation of the powder. Our raw materials are in accordance with the standards of International Environmental Protection Organization (IEPO) and RoHS 

2. Our unique molecules dividing equipment and technology to assure the small discrete of powder particles. 

3. Our original technology of positively pressure sintering improve the performance of the products. 

4. Our processing methods are vacuous melting, powdering of atmosphere protection, vacuum or atmosphere protection sintering and so on. 

5. Our original technology of material addition can make products which meet customers'requirements such as target magnets with the uniformity of low temperature parameters and height. 

6. The advanced machining processing such as laser beam drilling can do mass production of all kinds of magnets with high precision, such as the magnet for clock mechanism in watch, magnet for optical communicational products and so on. 

7. We can protect the customer rights, and make sure the mould are appointed.

Testing Center

We are ISO/TS16949:2002 certified and well implement all procedures strictly under control. Problem preventive actions and quality assurance are preoperly combined with special inspection for all procedures from raw material purchasing ,outside cooperating part manufacturing,inside manufacturing to shipping . We also install a complete set of physical and chemical test equipment to make sure that all our products are manufactured and shipped under strictly quality control .

Salt Spray Test :

Mainly test the surface treatment against the corrosion.  Usually the tested samples will be  continuous sprayed 24 hours in the 35℃ temperature to see if there is any rust appearance on the surface. 

Projection Instrument:

Mainly test the magnets with irregular shapes such as arc segments and any other irregular-shaped parts to see if their dimensions meet the customers' requirements or not.  

PCT Instrument:

Mainly test the magnets to prevent against corrosion on the high temperature and high atmospheric pressure . Usually the test condition is 120℃ temperature and 2 atmospheric pressure .

Heat& Humidity Instrument:

Mainly test the magnet to against corrosion on certain temperature and humidity . Usually the test condition is 80℃ temperature and 90%+/-3% humidity

Hysteresgraph:

Mainly test the magnetic characteristics of the magnet, including Residual (Br ), Coercive(Hcb) . Intrinsic  Coercive(Hcj), Max. Energy product(BH max) and any other related magnetic parameters.
