Soft Magnetic Alloy
Soft magnetic alloys are a class of materials with high permeability and low coercivity. These alloys can manipulate magnetic fields very effectively, making them indispensable in various electromagnetic applications. Their low coercivity makes them easy to magnetize and demagnetize, especially suitable for environments with frequent or rapid changes in magnetic fields.
These alloys, including common iron-nickel alloys, iron-cobalt alloys, iron-chromium alloys, and iron-aluminum alloys, are widely used in various components such as transformers, inductors, brushless DC motors (BLDC), current sensors, and electromagnetic shielding layers. They are also key materials in high-frequency communication systems, audio transformers, and magnetic heads for video equipment. Soft magnetic alloys are widely used in industries such as electronics, telecommunications, automotive, and aerospace, where they improve the production efficiency of applications requiring high-frequency operation and low energy loss.
Availability: We offer a range of soft magnetic alloys, including grades such as 1J22 (Hiperco 50, Vacoflux 50, Permendur49,VACODUR S PLUS), Permalloy 50, Permalloy 79, and Permalloy 80, in various forms, such as wires, strips, plates, and rods. In addition, we also offer custom manufacturing services, producing soft magnetic alloys of various sizes and shapes according to customer needs.
Main Featured Products:
1. 1J22 Series Products include 1J22, 1J22-MS, and 1J22-HS
1) 1J22 characteristics: Highest saturation magnetic induction intensity, high Curie point, and large saturation magnetostriction coefficient. Due to its high saturation magnetic induction intensity, its size can be greatly reduced when manufacturing motors of the same power; when used as an electromagnet, it can generate a large attraction force within the same cross-sectional area.
Applications: Widely used in aircraft generators, precision DC motors, electromagnet pole heads, end-welded tubes in magnetrons, telephone headset diaphragms, torque motors, precision servo motors, magnetostrictive transducer cores, etc.
