1J50 Permalloy

1J50 is a nickel-iron soft magnetic alloy with high initial and maximum permeability, low coercivity and high saturation magnetic induction strength.

The chemical composition of 1J50 alloy consists mainly of iron and nickel, which account for about half, respectively, and other alloying elements such as carbon, copper, sulfur, phosphorus, manganese, silicon and molybdenum, of which the content of manganese is less than the other elements. element is the most common, followed by silicon, followed by copper, and the higher content of carbon in steel is also within this content. There are many types of Permalloy. The simplest pozzolanic alloy is an alloy composed of two elements, iron and nickel. Depending on the content, there are many different kinds of Permalloy alloys. Currently, a large number of Permalloy alloys are other elements added to iron and nickel, such as molybdenum and copper. The purpose of adding these elements is to increase the resistivity of the material and thus reduce the production cost. Eddy current loss after core forming. Also, the addition of elements increases the hardness of the material, which is useful for use in wear applications, such as magnetic heads.
