Hengdian Kim direction of magnetic factory ---- Ferrite currently the most widely used soft ferrite magnets mahjong retailers, and materials can be divided according to purpose: MnZn power ferrite materials, communications and electromagnetic compatibility (EMC) with high permeability Mn-Zn ferrite materials, Mn-Zn ferrite yoke material, the RF broadband and electronic interference (EMI) suppression of nickel zinc ferrite material and other four categories. Material further to the high-frequency, high permeability and low loss development, which is two high and one low direction. Device development to small, surface mount chip and direction. Ferrite materials such as automotive and computer due to increase demand for high-grade magnet mahjong magnet, Chinese high-grade permanent ferrite proportion will rise rapidly. Expected Tenth Five-Year period Y30H-1 series of high-end products will be increasing the proportion of about 40% in 2000 over 2005, 60% (about 126,000 tons), production Y30H-2 brand above series of high-end products can reach 10 about% (about 21,300 tons), the proportion of total exports increased to more than 50%. Magnetization curve of magnetic material magnetic Hengdian Kim factory ---- magnetic material is made of ferromagnetic material or ferrimagnetic material composition, in the role of an external magnetic field H, there must be a corresponding magnetization M or the magnetic induction B mahjong machines use magnets, which varies with the magnetic field strength H curve is called the magnetization curve (M ~ H or B ~ H curve). Magnetization curve is generally non-linear, has two characteristics: magnetic saturation and hysteresis. That is, when the magnetic field strength H is large enough, the magnetization M reaches a saturation value Ms determined to continue to increase H, Ms unchanged; and when the value of the material M reaches saturation, the external magnetic field H is lowered to zero mahjong magnet Wholesale, M is not set to zero, but the change curve along MsMr. Working state of the material corresponds to a certain point, this point is often referred to as the operating point M ~ H curve or B ~ H curve. Mahjong magnet procurement, Kim Dae-magnetic factory and service-oriented, Jinhua mahjong magnet is provided by a large magnetic Hengdian gold plant. Hengdian Dongyang City, Kim Dae-magnetic Factory (www.jjdct.cn) is an industry leader in Jinhua, Zhejiang, electronics, electrical products manufacturing equipment, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs . In the Kim Dae-magnetic plant leadership with the staff warmly welcome all inquiries negotiations to create a large magnetic plant gold better future.
