Alloy vs Copper AC: Find the Differences 

Alloy vs Copper AC

Summer is here, and everybody wants to buy an AC for some relief from the scorching heat. While looking for options, a lot of us tend to compare ACs on size, weight, and price. Even though these are relevant parameters, there are some other factors that we must consider while buying an AC.

Alloy vs Copper AC

There are a lot of opinions on what to look for while buying an AC. One of the most popular ones is the Alloy vs Copper AC debate. There are a lot of arguments on which coil is best for AC -specifically on the choice of material used in condenser coils. These coils are usually made of copper, aluminium, or alloy. Their primary function is to dissipate all of the heat that escapes from your room into the atmosphere. Let us compare the differences between alloy and copper AC.


Raw copper is considerably costlier than alloys. As a result, any AC which contains a copper coil will inevitably cost more than that which uses an alloy coil. Using alloy coils has helped reduce the cost of ACs by a considerable amount. As far as the price is concerned, it is safe to say that alloy ACs are far superior to copper ones.

Similarly, the pliability of alloys is better than copper and hence is easier to bend. As a result, they have to use approximately three times more copper while making a coil of the same size and shape. However, thinner copper coils are now being made to lower the cost of copper coils.

Heat Transfer

The main function of any condenser coil in an AC is to transfer heat. While comparing copper's heat transparent coefficient to that of alloy, copper has a higher value. As a result, there is no doubt that it performs better in terms of heat transmission. 

Durability And Reliability

The copper metal is not as malleable as other metals which gives it better durability when compared to alloys. The durability of copper makes copper coils easy to clean and maintain. Even if they sustain minor damages or cuts, they can be easily mended. But alloy coils are comparatively brittle and can easily sustain damage. 

Their lack of durability makes it almost impossible to repair if they sustain any damage. Even in the case of corrosion, it is easier to clean a copper coil than an alloy because of its brittle nature. As a result, the damaged alloy coils are usually replaced. In such a case, if you ask

Thermal Resistance

Thermal resistance is an important factor that contributes to the durability of a coil. While comparing the thermal resistance of metals, copper ranks second while alloys come pretty lower in the list. In such aspects, copper ACs are undoubtedly better than alloy ones.

Energy Consumption-During power variations

Power variation is a common phenomenon in our country. Under such circumstances, we need to consider which AC consumes the least energy during power variations. The power conversion rate of alloys is substantially lower than that of copper in any given situation. This results in a higher power intake while using alloy ACs. If you want to efficiently reduce energy use, then you should prefer a copper AC.

Repair and Upkeep

The repair and upkeep of an AC coil depends upon its easiness while cleaning. In order to be able to clean the coil without worry, the material must not damage easily. Since copper is more durable than alloy, it is a step above alloy in this area. Hence maintaining copper ACs is easier while comparing to alloy ones.

This alloy vs copper AC comparison shows that alloy ACs are cheaper than copper ones. But it is also clear that copper AC dominates in every other aspect. They are more durable, reliable, and easy to clean. Copper ACs consume lesser energy during power variations and have a higher thermal resistance. They are also better at heat transfer. So, it all comes right down to one question. Do you want a durable AC that is costlier or would you focus on the cost and buy cheaper AC that might not perform that well?
