Precision alloys are metal materials with special physical properties (such as magnetic, electrical, thermal and other properties). The vast majority of precision alloys are based on ferrous metals, and only a few are based on non-ferrous metals.
Usually include magnetic alloys, elastic alloys, expansion alloys, thermal bimetals, electrical alloys, hydrogen storage alloys, shape memory alloys, and magnetostrictive alloys.
Alloys with high permeability and low coercivity in weak magnetic fields. Includes iron-silicon, iron-nickel, iron-aluminum, and iron-cobalt alloys.
Grades: 1J06, 1J12, 1J17, 1J18, 1J22, 1J30, 1J36, 1J38, 1J46, 1J50, 1J51, 1J54, 1J76, 1J77, 1J79, 1J80, 1J85, 1J87
Characterized by high hardness, strong anti-demagnetization ability, and high coercivity (greater than 20kA/m). Also known as hard magnetic alloy.
Grades: 2J04, 2J07, 2J09, 2J10, 2J31, 2J53, 2J84, 2J85
Includes high elastic and constant elastic alloys for precision instruments, frequency elements, and energy storage elements.
Grades: 3J01, 3J21, 3J53
Divided into Kovar alloys, ceramic sealing alloys, low expansion, and constant expansion alloys. Used in electronics and precision tools.
Grades: 4J28, 4J29, 4J32, 4J33, 4J36, 4J40, 4J42, 4J50
