Crafting Creative Solutions with Amorphous Ribbon Technology


Low-efficiency transformer cores have been plaguing electromagnetic operations for ages. While using standard transformer cores, businesses are forced to put in more money and effort in exchange for ridiculously low-efficiency rates with the output being much lower than the input.


But is there no way to solve this issue other than spending a lot of effort on insulation procedures and hefty solution-centered mechanisms?


There is– The Cobalt-based amorphous magnetic ribbon technology by Transmart!


Here is an in-depth overview of why amorphous magnetic material is a much more efficient choice over ferrite.

1. Low Core Losses

Core losses are a common occurrence in ferrite transformer cores as there are no built-in insulation measures to convert maximum input into output. This directly affects the productivity of the entire operation and causes financial losses for the business.


The Transmart amorphous ribbons are the perfect substitute for ferrite material transformer cores. The cobalt amorphous magnetic material has approximately zero magnetostriction, minimizing losses that take place due to friction of vibrations and noisiness of the system. With high magnetic permeability, maximum input is converted into output, solving the majority of core loss issues in the transformer.


A transformer using amorphous ribbons over ferrite alloys has a net output that is greater than its input by preventing energy losses from taking place.

2. Maximum Magnetic Permeability

The magnetic permeability of amorphous ribbons is much higher than other alloys giving it a net higher energy and cost efficiency.

At a maximum magnetic permeability (µ max) of 1000000, the cobalt amorphous magnetic material highly permits lower inductions. The permeability of magnetization excitation currents is also enhanced making the activation of the magnetic field a much faster process.


With much less magnetization current required to induce a magnetic field, the transformer can be directly magnetized saving the business from the high magnetizing current expenditure.

3. Zero Magnetostriction

The working principle of a transformer is to convert electrical energy into mechanical energy for mechanical operations. In order for this process to work in ferrite material cores, a phenomenon called magnetostriction takes place.


Magnetostriction converts electrical energy into mechanical energy by rapid vibrations, which causes not only heavy friction losses but also losses in the form of noise. Using standard ferrite cores, therefore, can cause your transformer operation to have a net negative output rate, thus hurting net productivity.


For Transmart cobalt-based amorphous ribbons, the magnetostriction value is zero!


This makes amorphous cobalt and iron ribbons much less noisy and eliminates the friction that takes place due to vibrations.

4. Elasticity and Softness

For standard ferrite transformer core materials, there are two extremes that their functionality generally swings towards;


● Hyper-rigidity

● Hyper-flexibility


Hyper rigidity means that the core material is too hard to provide any flexibility and thus, even a slightly higher level of strain can cause the core to snap. Similarly, when the ferrite core is made to be ductile and malleable, it becomes so flexible that there is absolutely no sturdiness left in the material and so, it can not perform its function efficiently.


With a thickness of 18-25µm, the amorphous ribbons are sturdy yet soft enough to have high flexibility and elasticity. This dual nature gives the amorphous magnetic material the perfect balance to work in a range of conditions, thus adding to the life of the operation. When too much strain falls onto the amorphous ribbons, they have the ability to withstand it and then return to their original condition.

5. Noise Suppression

The magnetostriction phenomenon present in ferrite transformer cores can cause a lot of core losses in the form of vibratory friction and noise which can drastically affect the output-to-input ratio of the transformer.


To combat this unnecessary energy loss, the Transmart amorphous ribbons reduce the magnetostriction to a spectacular zero percent, causing the noise to be eliminated and vibrations to die down. This noise suppression provides a much better environment for a business to run its operation and also significantly reduces the effort that would otherwise go into searching for noise suppression solutions.

6. Working Temperature Range

Using a rapid solidification process, molten cobalt is poured into thin ribbons of compact metal and cooled rapidly at a very high cooling rate to create cobalt amorphous ribbons for transformer cores.


The working temperature range for the amorphous magnetic material is -40-90°C. This makes the amorphous ribbons much more functional over a range of temperatures. This temperature factor adds to the stability and longevity of the transformer, ensuring that the core wouldn't cave if the temperature fluctuates and has a high potential for returning to its previous position with a linear graph.


The iron and cobalt amorphous ribbons are a lot more efficient for the net productivity of a business as it not only eliminates unnecessary energy losses but also provide longevity to the operation by zero magnetostriction and high productivity.


When it comes to the range of functioning ability and flexibility, the amorphous magnetic material is the perfect pick for transformer cores!
