Problems solved by technology

[0002] At present, iron-nickel high-permeability alloys, that is, Permalloy, are usually made of polybutene and polycarbonate materials, among which polybutene is mainly used for clock stators, and polycarbonate is used for transformers and magnetic shielding. However, The cost of these alloys is high, and the magnetic properties are gradually unable to meet the requirements of current electronic products. Continue to reform and upgrade. The current permalloy still has a lot of room for development in terms of magnetic permeability and high-frequency characteristics. Now It is very important to study a permalloy with low cost, high magnetic permeability, excellent high frequency characteristics and low coercive force.

Abstract

The invention discloses a permalloy. The permalloy is prepared by smelting the components, by mass percentage, 45-60% of nickel, 1-2% of manganese, 2-5% of silicon, 3-6% of phosphorus, 1-4% of sulfur, 1-2% of aluminum and 35-45% of iron. The permalloy has the beneficial effects of being low in cost, high in magnetic permeability, excellent in high frequency characteristic and low in coercive force.

Description

technical field [0001] The invention relates to an alloy, in particular to a permalloy. Background technique [0002] At present, iron-nickel high-permeability alloys, that is, permalloys, are usually made of polybutene and polycarbonate materials, among which polybutene is mainly used for clock stators, and polycarbonate is used for transformers and magnetic shielding. However, The cost of these alloys is high, and the magnetic properties are gradually unable to meet the requirements of current electronic products. Continue to reform and upgrade. The current permalloy still has a lot of room for development in terms of magnetic permeability and high-frequency characteristics. Now It is very important to study a permalloy with low cost, high magnetic permeability, excellent high-frequency characteristics and low coercive force. Contents of the invention [0003] In order to overcome the shortcomings of the existing rubber, the invention provides a permalloy. [0004] The...
