What is Amorphous Metal?

 

Contrary to traditional metals with an orderly atomic structure, amorphous metal is a unique metal that comes with a disordered structure. Its irregular non crystalline structure offers desirable properties such as high strength and good elasticity.

Also, amorphous metals bring superior magnetic properties, which makes them ideal material for transformer cores. This material is produced by rapidly cooling molten metal, which prevents atoms from forming a regular lattice structure.

The Role of Amorphous Metal Transformers

In a transformer, the onus is on the core to transfer magnetic flux between primary and secondary windings. How efficiently this process takes place depends on how much the core material reduces energy losses due to hysteresis and eddy currents.

This is where amorphous metal helps. Transformer cores made of amorphous metals significantly reduce core losses when there is a change in direction of the magnetic field.

Advantages of Amorphous Metal Transformers

It increases efficiency and reduces energy losses

When the efficiency of amorphous metal cores is compared with transformers made of silicon steel, there is a huge gap. Transformers with amorphous metal cores reduce energy losses as much as 70%.

While the non crystalline structure of amorphous metal contributes to reduction in hysteresis loss, its thin ribbon-like form keeps eddy current loss minimal. As a result, there is less heat generated and transformers perform much better.

Therefore, amorphous makes an ideal choice for applications such as power grids and industrial facilities where transformers have to operate non-stop.

It helps reduce carbon footprint

The higher the energy efficiency, the lower the carbon footprint. Power utilities can reduce a lot of electricity wastage by adopting amorphous metal transformers. This helps utilities reduce the burden of generating power in excess.

As a result, it contributes to the collective global goal of reducing carbon footprint and achieving energy-saving targets.

It reduces operational and maintenance costs

Since transformers with amorphous metals experience less energy losses, they do not generate much heat. This reduces cooling requirements, contributing to reduction of operating and maintenance costs for power distribution companies.

It extends service life of the transformer

Amorphous metal transformers operate at lower temperatures, therefore, they do not undergo extreme wear and tear, extending lifespan of insulation and other components. This allows transformers to provide services for a longer period.

It improves load performance

Amorphous metal cores can perform efficiently under varying load conditions. They are ideal to use in applications where load fluctuations are common. For example, renewable energy grids and industrial machinery.
