Stock 6mm 8mm 10mm permalloy 80 mumetal 1J85 core transformer round bar rod
Permalloy or Carpenter HyMu 80 is a nickel-iron-molybdenum alloy providing great resistance to general corrosion and humidity. It has high magnetic permeability. It is basically a Nickel-IronMolybdenum alloy that provides high magnetic permeability with low hysteresis loss. It is commonly used in magnetic toroids, transformer cores, home theater systems and shielding applications.
Heat Treatment
Permalloy 80 not hardenable by heat treatment. Annealing can be performed in a dry hydrogen atmosphere at 1176°C (2150° F) for 4 h, followed by furnace cooling to 593°C (1100°F), and then a cooling rate of 260°C (500°F)/ h from 593 to 372°C (1100 to 700°F). Air cooling should be done to 372°C (700°F). Strain relief annealing can be performed at 927°C (1700°F) for 1/2 h in a dry hydrogen or inert gas atmosphere.

Soft magnetic alloys are a class of alloys with high permeability and low coercivity in weak magnetic fields. According to the different elements that make up the alloy, it can be divided into electromagnetic pure iron (industrial pure iron), iron-silicon alloy, iron-nickel alloy, iron-aluminum alloy, iron-silicon-aluminum alloy and iron-cobalt alloy, etc.1J06,1J12,1J17,1J18,1J22,1J30,1J36,1J38,1J46,1J50,1J51,1J54,1J76,1J77,1J79,1J80,1J85,1J87
Permanent magnet alloy not only has high hardness and mechanical properties, but also has strong anti-demagnetization ability, high coercivity value (greater than 20kA/m), magnetic "hard" and other characteristics, so it is also called hard magnetic alloy.2J04,2J07,2J09,2J10,2J31,2J53,2J84,2J85Elastic alloys include high elastic alloys and constant elastic alloys. It is used to make elastic elements such as elastic sensitive elements, energy storage elements and frequency elements in precision instruments.3J01,3J21,3J53Expansion alloys(Invar Alloy) are divided into Kovar alloys, ceramic sealing alloys, low expansion alloys, and constant expansion alloys. Widely used in electronic industry, precision measuring tools, precision instruments and low temperature engineering and other fields.4J28,4J29,4J32,4J33,4J36,4J40,4J42,4J50
