What is the Difference between Copper and Aluminium Transformer?

What are the two types of transformers?

Copper wire wound transformers and aluminum wire wound transformers

What materials should be selected for transformer windings?

If you want to save costs, you can buy aluminum wire transformers. However, after the transformer life ends, the residual value of aluminum transformers will be lower than that of copper transformers. If the copper price fluctuates greatly, the residual value of copper transformers may be higher than the value at the time of purchase.

What are the differences between copper wire transformers and aluminum wire transformers?

1. Performance
Copper wire transformers: good conductivity, high mechanical strength, and high thermal conductivity
Aluminum wire transformers: aluminum has a high resistivity and poor strength

2. Price
Copper wire transformers: high price
Aluminum wire transformers: low price

3. Features
Copper wire transformers: strong short-circuit resistance, that is, the dynamic stability and thermal stability of the transformer are also strong.
Aluminum wire transformers: aluminum is more active and easily oxidized.

4. Size
Copper wire transformers: copper wire transformers are small in size.
Aluminum wire transformers: aluminum wire transformers are relatively large in size.
