Iron-nickel-based, cobalt-based amorphous alloy
Nov 09, 2018

The iron-nickel-based amorphous alloy is composed of 40% Ni, 40% Fe and 20% metalloid elements, which has medium saturation magnetic induction [0.8T], high initial permeability and high maximum magnetic permeability. And high mechanical strength and excellent toughness. Low iron loss at medium and low frequencies. The heat treatment in the air does not oxidize, and a good rectangular return line can be obtained after annealing the magnetic field. The price is 30-50% cheaper than 1J79. The application range of iron-nickel-based amorphous alloys corresponds to medium-nickel permalloy, but the iron loss and high mechanical strength are far superior to crystalline alloys; instead of 1J79, it is widely used in leakage switches, precision current transformer cores, magnetic Shielding, etc. The iron-nickel-based amorphous alloy is the earliest developed in China, and it is also the most widely used amorphous alloy in domestic amorphous alloys. The annual output is about 200 tons. The heat treatment in air does not occur in iron oxide-nickel-based amorphous alloy (1K503). Invention patents and US patents.
