News - 1J85 nickel base soft magnetic alloy

1J85 Iron nickel molybdenum soft magnetic alloy is an iron nickel base alloy, mainly composed of iron, nickel and molybdenum and other elements, is a high performance magnetic material. It has excellent soft magnetic properties such as high initial permeability and low coercivity. Widely used in the electronics industry, often used in transformer core, magnetic head, magnetic shielding, etc., can reduce loss, improve the efficiency of electromagnetic conversion and signal induction.

1J85 nickel alloy soft magnetic alloy features include:

High permeability: The permeability of 1J85 alloys is very high, usually reaching more than 10,000, and even between 100,000 and 150,000 in some cases. This enables it to rapidly and fully magnetize under the action of magnetic fields, improving electromagnetic properties.

Low coercivity: 1J85 alloys have A very low coercivity, usually between 1.5 A/m and 2.5 A/m. The low coercivity means that the alloy is easy to magnetize and demagnetize, which is conducive to reducing hysteresis loss and improving the efficiency of electromagnetic equipment.

Low hysteresis loss: Due to its low coercivity, 1J85 alloys exhibit low hysteresis loss in alternating magnetic fields. This helps to effectively reduce energy loss and improve equipment efficiency in high-frequency electromagnetic equipment.

Good temperature stability: The magnetic properties of 1J85 alloy remain stable over a wide temperature range, and can adapt to the needs of a variety of working environments.

Excellent machining performance: 1J85 alloy can be used for various mechanical processing, such as stamping, cutting and grinding, to adapt to different design requirements. At the same time, it also has good plasticity and strength, which is easy to make various shapes of magnetic components.

Higher resistivity: 1J85 alloys have higher resistivity, which helps reduce eddy current losses and improve energy efficiency in high-frequency environments.

In the entire 1J85 alloy production process, the process parameters of each link need to be strictly controlled to ensure the quality and performance of the final product.

1. Vacuum induction melting: This is one of the most commonly used preparation methods. The alloy raw material is melted by induction heating under vacuum conditions, and refined and degassed during the smelting process to obtain high quality alloy ingot.

2. Hot forging opening: The alloy ingot obtained by melting is hot forging to improve its internal structure and performance.

3. Hot rolling: The four-high reversible hot rolling mill is used to hot roll the alloy blank to make it into a steel plate or strip with a certain thickness and width.

4. Cold rolling: The hot rolled steel sheet or strip is cold rolled through a four-roll reversible cold rolling machine to further thin and improve its surface quality.

5. Bright annealing furnace intermediate annealing: During the cold rolling process, intermediate annealing may be required to eliminate internal stress and improve magnetic properties.

6. Cold rolling to finished product: After several cold rolling and possible annealing treatment, the final 1J85 alloy strip or sheet meets the requirements.
