Hengdian Kim Dae-magnetic Factory ----- magnet manufacturers briefly thni magnet magnet-type crystal structure is what the manufacturers tell you, rh2Zn17 type crystal structure is one of the most basic type of crystal structure of rare earth permanent magnet compounds. R2Cb17 and R2Fe17 compounds in the low temperature region most have Th2Z1 structure. Th2Ni17 and Th2Zn17 is allotrope, both the structure is very small h2Zn17 rod-type crystal structure, it belongs to rhombohedral screen or called trigonal system, space group 3m. Within a single cell contains three Th2Z sub-type. A total of 57 atoms in the unit cell. A total of 6 Th (or R) atom. Hengdian Kim Dae-magnetic plant manufacturers _ ----- magnet magnet manufacturers talk about giant magnetostrictive material applied magnet manufacturers tell you to use high-quality speaker magnet, this property has been used to manufacture a variety of energy conversion devices Quality specifications speaker magnets, such as an ultrasonic generator, sensors. For general common magnetic materials, the magnetostrictive coefficient is small quality speaker magnet, only 0-30ppm. However, in recent years found that certain rare earth iron made of a material having a great magnetostrictive coefficient, reaching more than 1000ppm, because lead is called the giant magnetostrictive material or giant magnetostrictive material. With such large magnetostriction characteristics, can create a variety of energy conversion devices, the electromagnetic energy is converted to mechanical energy and vice versa. The price of high-quality speaker magnets, Taizhou quality speaker magnets, magnetic plant quality and reliable Kim provided by large magnetic Hengdian gold plant. Hengdian Kim Dae-magnetic Factory (www.jjdct.cn) strong, credible, Zhejiang Jinhua electronics, electrical equipment manufacturing industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead the Kim Dae-magnetic factory and you hand into the brilliant, for a better future!
