Permalloy Audio Transformer 600:10K 600:600 50K:600 10K:10K For Power Amplifier

1.Product Description:

Permalloy refers to an iron-nickel alloy with a nickel content of 30-90%. The grades of domestic permalloy are: 1J34, 1J50, 1J51, 1J67, 1J79, 1J77, 1J85; 1 means soft magnetic alloy, J means precision alloy, and the following number means nickel content. Application characteristics of permalloy: The operating frequency is from 50Hz to 20kHz, and the temperature is relatively high, such as high-precision current, voltage transformers, pulse transformers, isolation transformers, magnetic amplifiers, etc.

According to the content of nickel in the nickel-iron alloy, 600:10K 600:600 50K:600 10K:10K Permalloy Audio Transformer can be used in different occasions:

1.35% to 40% have lower core loss. Such alloys are suitable for square wave transformers, DC converters, etc.

2.45% to 50% Alloys in this composition range have the highest saturation magnetization among permalloys. Commonly used in magnetic amplifiers, choke coils and transformers.

3.50%～65% The alloy in this composition range has the highest Curie temperature and high saturation magnetization, which can produce strong induced magnetic anisotropy. Suitable for inductive components.

4.70% to 81% Permalloy in this composition range has the highest magnetic permeability. Such alloys are suitable for transformers, choke coils, magnetic heads, magnetic shields, etc.

2.Dominance

Permalloy is an alloy with iron (Fe) and nickel (Ni) as its main components, usually with small amounts of other elements. It offers the following significant advantages:

1. High magnetic permeability
--Enhanced Magnetic Field Response: The extremely high permeability of pozzolanic alloys produces a strong magnetic induction strength in the presence of a weak external magnetic field. In transformers, for example, this means that the same change in magnetic flux can be achieved with fewer turns, which in turn reduces the copper losses in the windings and increases the efficiency of the transformer.

--Improved inductive performance: For inductive components, high permeability allows the Permalloy to store and release magnetic energy more efficiently. In electronic circuits, inductors using Permalloy cores can achieve larger inductance values in smaller sizes, helping to miniaturize electronic equipment.

2. Low Hysteresis Loss
--Energy saving and high efficiency: Hysteresis loss is the amount of energy consumed by a magnetic material due to the phenomenon of hysteresis during repeated magnetization.Permalloy's narrow hysteresis return line indicates minimal energy loss during magnetization and demagnetization in an alternating magnetic field. This characteristic is particularly important in high-frequency circuits, such as in the transformers of switching power supplies, where it can significantly reduce energy loss, improve the conversion efficiency of the power supply, and reduce heat generation.
