介绍 | Carpenter High Permeability "49"® is a 48% nickel-iron alloy that possesses the highest saturation flux density of any nickel-iron alloy. The saturation flux density of about 16000 gauss (1.6 tesla) combined with high magnetic permeability and low core loss makes this a versatile alloy with many potential applications. The alloy is available in three grades: 1. Carpenter High Permeability "49" Alloy Available in bar, wire, rod and strip form in thicknesses of 0.020" (0.51 mm) and over by various widths, this grade has been used for magnetic shielding and sensitive relay and solenoid components. 2. Carpenter High Permeability "49" Alloy-Rotor Grade This grade is specially processed to yield uniform, isotropic properties and is supplied as cold rolled strip in thicknesses from 0.004 to 0.020" (0.1 to 0.51 mm) It has been used for laminations for rotating components such as resolvers and servo-synchros where the magnetic properties must be highly isotropic (i.e., not directionally dependent). 3. Carpenter High Permeability "49" Alloy-Transformer Grade This semi-isotropic grade is specially processed to produce higher magnetic permeabilities parallel to the rolling direction of the strip and is suitable for use in transformer laminations and tape wound cores where the directionality of magnetic properties can be an advantage. It is available as cold rolled strip in thicknesses ranging from 0.001 to 0.020" (0.03 to 0.51 mm). Applications: Carpenter High Permeability "49" alloy has been used in laminated cores for instrument transformers, magnetic shields and cores for certain electronic and communications devices in which extremely high permeability at low magnetizing forces greatly increases the efficiency and effectiveness of the equipment. Because of its high permeability, it has also been used in solenoid cores and sensitive relays that must respond to low magnetizing forces. |
