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.
