Product Description

Product Description

Silicon Steel Magnetic Core

Silicon steel is an alloy, adding a small amount of silicon in pure iron (generally below 4.5%) the formation of iron-silicon alloy known as silicon steel, this type of core has the highest saturation magnetic induction strength value of 20,000 gauss; due to their better magnetoelectric properties, but also easy to mass-produce, inexpensive, the impact of mechanical stress and other advantages, in the power electronics industry to obtain an extremely wide range of applications, such as power transformer Power transformers, distribution transformers, current transformers and other cores.

For small motors, reactors and relays, pure iron or low-silicon steel sheet; for large motors, high silicon hot-rolled silicon steel sheet, single-orientation or non-orientation cold-rolled silicon steel sheet; transformers are often selected single-orientation cold-rolled silicon steel sheet. In the frequency of use, commonly used strip thickness of 0.2 ~ 0.35 mm; in the use of 400Hz, often choose 0.1 mm thickness is appropriate. The thinner the thickness, the higher the price.
