Alnico casting process:
Constituting the metal components of different magnetic properties are different, and thus uses are different alnico has two different production processes: casting and sintering the casting process can be processed into different sizes and shapes, as compared with the casting process, sintered products limited to a small size, their production out of the rough product size tolerances, casting good workability in permanent magnetic materials, the cast alnico reversible temperature coefficient has the lowest operating temperature up to 500 degrees Celsius.
Advantages: remanence high (up to 1.35T), low temperature coefficient. Temperature coefficient of -0.02% / ℃, while the maximum temperature up to about 520 ℃. Disadvantages coercivity when very low (typically less than 160kA / m), non-linear demagnetization curve. Therefore, although easy alnico magnet is magnetized, is also likely to demagnetization.
Haiying Gui Magnet Co., Ltd. specializes in various types of magnetic materials, with a number of foreign-funded enterprises have a good working relationship, the production of other products are also exported to Southeast Asia and Europe and America, has become a lot of well-known enterprises suppliers. More than ten years of experience in magnet production, the main products ferrite magnets, rare earth NdFeB magnets (magnetic button), aluminum, nickel and cobalt. SmCo Rubber magnet tens of thousands of varieties of five categories can also be based on your needs by mold or cutting to create new specifications. Products are widely used in speakers, motors, refrigerators, gift boxes, gift bags, magnetic stationery, advertising, printing, magnetic health products. "Reliable quality, abide by the contract" is our aim for many years. The company with a positive attitude, open up the market, customers are welcome to call us, to discuss business.
