Amorphous core transformers save energy by cutting core losses by 70%. They are 95% to 98% efficient, wasting less electricity. This makes them eco-friendly and reduces pollution. However, there are some significant amorphous core transformer disadvantages to consider. The materials for these transformers cost 40–50% more than regular ones. Additionally, they are fragile, hard to recycle, and tricky to manufacture. These issues can make them less suitable for certain applications. Understanding these disadvantages helps you determine if they are the right choice for your needs.
Amorphous core transformers save up to 98% energy but cost more because of pricey materials.
They are delicate and can break easily, so they aren't great for places with lots of stress or short circuits.
You need to handle and install them carefully. If not, they might not work well and could waste energy.
When damaged, they often need full replacement since fixing them is hard and expensive.
Think about your project's needs. These transformers are better for low-power, energy-saving uses, not for high-power or tough conditions.
Amorphous core transformers have lower magnetic density than regular cores. Their magnetic density is about 1.56T, 20% less than 1.9T in silicon steel. This means they handle less magnetic energy. Oil-based transformers usually stay below 1.35T, while dry ones stay under 1.2T. This lower density needs more copper to work properly. Using extra copper can raise costs and lower efficiency.
Amorphous metals are brittle and break easily. They can get damaged during use or making them. Unlike steel cores, they can't handle constant stress. Vibrations or short circuits can cause permanent damage. Once broken, they can't be fixed, and the core won't work well. This makes it hard to find problems and increases the chance of failure in tough conditions.
Amorphous cores need careful handling. Stress can hurt their performance. If handled wrong during setup or transport, the core strips can weaken. This lowers efficiency and increases energy loss. To prevent damage, the core must be supported and protected from force. This makes them harder to use in places where they need frequent moving or changes.
Amorphous transformers are noisier than regular ones. This happens because their cores deform more, about 10% more than silicon steel. The deformation causes vibrations, which create noise you can hear. Controlling this noise is hard in places with strict rules. For example, Southern Power Grid and State Grid have tough noise standards. To meet these, designers lower magnetic density, which can hurt performance.
Amorphous transformers don’t stay efficient forever. Over time, they lose performance. Studies show core and copper losses grow as they age. This makes them less reliable for long-term use. The problem is worse in places with changing loads or tough conditions.
Amorphous transformers can’t handle overloads well. Their magnetic density is lower, 1.56T compared to 2.03T in silicon steel. This means they can’t manage sudden load increases easily. They need bigger cores, which are harder to fit in small spaces like cities. Also, 18% of these transformers fail European Union bids due to design issues. This makes them less useful for different infrastructure needs.
Amorphous core transformers are not good at handling short circuits. A short circuit happens when a fault causes a sudden current surge. Transformers should survive this, but amorphous cores often fail.
The core material is a key reason for this problem. Amorphous metals are brittle and weaker than silicon steel. During a short circuit, strong electromagnetic forces can bend or crack the core. This damage lowers efficiency and might cause the transformer to stop working.
Did you know? Short-circuit forces can be 20 times stronger than normal. Transformers need to be tough to handle these extreme events.
Another problem is how amorphous cores are designed. To save energy, manufacturers use thinner core strips. This reduces energy loss but makes the core weaker. Thin materials can’t handle the stress from short circuits. This balance between saving energy and being strong makes them less reliable in risky areas.
Fixing them after a short circuit is also hard. Once damaged, amorphous cores are tough to repair. Often, the whole transformer needs replacing. This increases costs and downtime, making them less useful where short circuits happen often.
If your project has frequent faults or high short-circuit risks, these transformers may not work well. Their weakness in handling impacts can raise costs and cause delays. Always think about your project’s needs before picking this type of transformer.
Amorphous core transformers have problems with strip length limits. These metal strips come in fixed sizes, restricting core size. For bigger transformers, smaller strips must be joined together. This makes the process harder and less efficient.
Tip: Joining small strips can cause gaps or uneven spots. These flaws lower performance and waste more energy.
Because of this, amorphous cores are not ideal for large projects. If you need a big transformer, silicon steel cores might work better.
Amorphous metals are not made as much as silicon steel. Only a few companies produce them, causing supply issues. If there are no local suppliers, importing them costs more and takes longer.
Making amorphous cores also needs special tools and skills. In remote areas, finding trained workers can be tough. These problems make manufacturing and installing them more complicated.
Amorphous metals have lower density than silicon steel. To perform well, they need more copper windings. Copper is pricey, so this raises the transformer's cost.
Extra copper also makes the transformer heavier. Moving or installing it in tight spaces becomes harder. You may need extra tools or supports, adding to the expense.
Did you know? Copper prices change often. This makes it tricky to estimate the total cost of an amorphous core transformer.
Amorphous core transformers are bigger and weigh more than regular ones. This is because their lower saturation flux density needs a larger core to handle energy. Their size makes it tough to install them in small spaces, like city substations. If you’re upgrading old substations, their larger size can cause problems.
Their extra weight adds more challenges. You’ll need special tools to move and install them. Equipment like cranes or forklifts becomes necessary, raising costs and making planning harder. In remote areas, this can slow down work and require extra effort.
Tip: Check your space and transport options before picking an amorphous core transformer. This helps avoid surprises during setup.
The bigger size also makes storage and movement tricky. Sometimes, you might need to change buildings to fit the transformer. For example, doors, paths, or platforms may need adjustments. These changes can increase project costs and take more time.
Main issues with bigger and heavier transformers:
Need more room for setup, especially in tight spaces.
Require special tools for moving and installing.
Make upgrading old substations harder.
If your project has limited space or strict weight rules, think carefully. Amorphous core transformers save energy but may not work well in all situations. Always check your site’s needs before deciding.
Amorphous core transformers cost more upfront than regular ones. This is because making them is harder and uses pricier materials. Their special design needs advanced methods, which raises production costs. The materials in these transformers also cost more than those in standard models.
Even though they cost more at first, they save money later. Their energy efficiency lowers running costs over time. This makes them a smart choice for long-term savings. But the high starting price can be a problem for tight budgets. While they save energy, you should decide if the future benefits are worth the upfront expense.
Note: These transformers work well for energy-saving projects but may not fit budget-focused plans.
Getting amorphous metals can be tough. About 70% of these materials are made in China, creating supply issues. Shipping delays can add 8–12 weeks to delivery times. These delays might mess up project schedules and push buyers to choose silicon steel instead.
Making these transformers also needs special tools and methods. This raises production costs by 20–30%, making them harder to get. In places without local suppliers, this problem gets worse. If your project needs quick delivery and cheaper materials, limited supply could be a big challenge.
Taking care of amorphous transformers is harder than regular ones. Their cores are fragile and can break under stress or short circuits. If damaged, fixing them is often impossible. Many times, the whole transformer must be replaced, which costs more and takes longer.
These transformers also fail more often. Amorphous metals are brittle and don’t last well in tough conditions. If your project has changing loads or harsh environments, they might need more repairs. This can raise maintenance costs and make them less reliable over time.
Tip: Think about how much care these transformers need before choosing them.
Amorphous core transformers usually need to be replaced when they fail. Unlike regular transformers, their fragile cores make fixing them very hard. If the core gets damaged, it loses its magnetic power, which is needed to work well. Fixing these cores isn’t practical because it needs special tools and skills that are rare.
Why does this matter?
If your transformer breaks, you might face higher costs and longer delays since replacing the whole unit is often the only solution.
The brittleness of amorphous metals is a big reason for this problem. These materials can’t handle repeated stress or impacts. For example, a short circuit can bend or crack the core permanently. Even small damage can hurt how the transformer works, causing energy loss or total failure.
You should also think about how hard it is to find replacement parts. Amorphous core transformers use special materials that are harder to get than silicon steel. This can delay replacements, especially in faraway places or during supply problems.
Main reasons why replacement is needed:
Fragile cores are tough to fix.
Repairs need rare tools and skills.
Replacement parts are hard to find.
Tip: Handle and maintain your transformer carefully to avoid frequent replacements. Taking care of it can make it last longer and lower the chance of failure.
If your project is important or in areas with many faults, think carefully. Needing full replacements can raise costs and cause delays, making these transformers less ideal for risky situations.
Amorphous core transformers are very energy-efficient, reaching up to 98%. Regular silicon steel cores are less efficient, at 94% or lower. But these transformers have downsides like being fragile, costing more, and being harder to make. These issues make them less useful for big projects or tight budgets.
They work well in certain areas:
Systems that save energy
Solar power setups
Energy storage systems
Their design fits low-power uses where saving energy matters more than cost. Always check your project’s needs before picking this type of transformer.

These transformers are pricier because of special materials and tools. Amorphous metals are expensive and harder to find. Making them needs advanced machines, which raises costs. But they save energy, which can lower expenses later.
No, they are not great for high-power needs. They can't handle big loads due to low magnetic density. Overloads and short circuits can damage them easily. For high-power tasks, regular transformers work better.
They don’t do well in harsh places. Their cores are brittle and break under stress or heat changes. These problems can cause failures. For rough environments, stronger transformers are a better choice.
Fixing them is very hard. The fragile core often gets damaged permanently. Most of the time, you have to replace the whole transformer. This takes more time and costs more money.
They need larger cores because of their lower magnetic density. This makes them bigger and heavier. Moving and setting them up is harder, especially in small spaces. Check your site’s size and weight limits before choosing one.
