Copper Vs Aluminum Piping for Air Conditioning

Copper Vs Aluminum Piping for Air Conditioning Aluminum and copper are the two most common metals used in air conditioner pipes. Most contemporary air conditioners use copper, while aluminum pipework is gradually becoming outdated. It might be difficult to decide between the two pipe technologies because each has advantages and disadvantages of its own.

Listed below are a few advantages and disadvantages between the two: Aluminum The price of aluminum is a significant benefit. It is only logical that its price is lower because it is a far more common mineral than copper in the Earth's crust and much lighter than copper, weighing around 30% less.

One drawback of using aluminum is that, when exposed to atmospheric air in the vicinity of metal and brass connections (nuts, splices, nipples, etc.), the phenomenon known as galvanic corrosion can take effect. This means that aluminum can become porous in the flange and start leaking after just one or two years of use.

Another crucial factor in favor of aluminum tubing is its resistance to formicary corrosion.

Common lubricating oils trigger a chemical process that results in formicary corrosion, which calls for oxygen, water, and an organic acid. It is a particular form of early failure using copper in air conditioning systems. It has long been an issue with copper tubing used in HVAC applications.

Only copper-based alloys are subject to formicary corrosion. It has no effect on aluminum. Since it is estimated that 10% of interior heat exchangers fail early owing to formicary corrosion, substituting copper with aluminum has the dual benefit of reduced initial raw material costs as well as a reduction in warranty expenses.

Copper The primary benefits of copper are its better thermal conductivity, quicker heating, and cooling, which improve device efficiency, and the fact that its tubes are stiffer than those of aluminum, making them stronger and more resistant to oxidation.

Additionally, if there is deterioration, it may be fixed by welding, which cannot be done with aluminum tubes.

An air conditioner's copper pipes are continually in touch with water and air of various temperatures. In such an environment, most untreated metals corrode quite fast. Copper pipe's capacity to resist corrosion means that the air conditioner will not have pipe breaks, gas leaks, or other dependability problems and that it will last a long time.

Considering that copper often costs twice as much as aluminum since metal is not as abundant in nature, as we said earlier, this is its sole drawback. In addition, the material is heavier.
