在电机电器制造工业和自动化技术中,往往需要具有低的导磁率μ和高的电阻率ρ的合金材料。铝合金、铜合金及镍低磁铸铁,虽然导磁率低,但分别由于膨胀系数、电阻率、资源情况等原因,应用受到一定限制。而锰铜低磁铸铁,由于低的导磁率、高的电阻率、与钢铁材料的膨胀系数接近、国内资源丰富,因而具有广泛的应用价值。

In the electrical and electronics manufacturing industry and automation technology, alloy materials with low permeability μ and high resistivity ρ are often required. Aluminum, copper alloy and nickel low magnetic iron, although the permeability is low, but due to the expansion coefficient, resistivity, resource conditions and other reasons, the application is subject to certain restrictions. Manganese copper low magnetic iron, due to the low permeability, high resistivity, close to the expansion coefficient of steel materials, domestic rich resources, which has a wide range of applications.
