A foreign trade customer in Shanghai is the annual partner of the director of the Shuangxing Injection Shoe Factory. This year, when it signed an ordering contract with the customer, the customer offered to increase the order volume by 7%. Recently, the Double Star Injection Shoe Factory obtained Shandong's only 15,000 volt high-voltage insulated shoes “National Industrial Production Permitâ€, which further strengthened customer confidence and they actively increased their orders.
The factory exerts its technical advantages and technological advantages in the production of labor insurance shoes. Thanks to its brand-name effect and multi-faceted efforts, it has successfully entered the double-star labor insurance shoes into large enterprises such as Qingdao Port, CSR Quartet, Qingdao Special Automobile Group and Liuting Airport. New marketing areas.
Alnico magnets are produced by casting or sintering processes.[8] Anisotropic alnico magnets are oriented by heating above a critical temperature and cooling in the presence of a magnetic field. Both isotropic and anisotropic alnico require proper heat treatment to develop optimal magnetic properties-without it alnico's coercivity is about 10 Oe, comparable to technical iron, which is a soft magnetic material. After the heat treatment alnico becomes a composite material, named "precipitation material"-it consists of iron- and cobalt-rich[9] precipitates in rich-NiAl matrix.
Alnico's anisotropy is oriented along the desired magnetic axis by applying an external magnetic field to it during the precipitate particle nucleation, which occurs when cooling from 900 °C (1,650 °F) to 800 °C (1,470 °F), near the Curie point. Without an external field there are local anisotropies of different orientations due to spontaneous magnetization. The precipitate structure is a "barrier" against magnetization changes, as it prefers few magnetization states requiring much energy to get the material into any intermediate state. Also, a weak magnetic field shifts the magnetization of the matrix phase only and is reversible.
Alnico magnets are ideal for high temperature applications up to 550ºC
. Cast Alnico Magnet is very stable, has good corrosion resistance and a typical hardness of 50 Rockwell C. Once cast, the material is so hard that the only machining possible is grinding
. Cast Alnico Magnet represents the most versatile magnet material available. The range of properties can be accurately designed for specific applications by changes to element analysis and heat treatment.
