What is the difference between copper pipe and iron pipe or aluminum pipe freezer

The direct cooling effect of copper pipe and iron pipe or aluminum pipe is the same. However, copper pipes have a long service life and are durable, while iron pipes are prone to internal leakage and damage when iron pipes have not been in operation for several months. The aluminum tube is not easy to leak and damage, and the cooling effect is the same, so if there is an aluminum tube freezer, you can also choose it. However, if the price is the same and the same brand, the copper tube freezer is preferred.
