Freezer aluminium tube can be used for several years
The aluminum pipe is more corrosion resistant than the iron tube, and the iron pipe is not corrosion resistant, so I suggest you choose the aluminum pipe!In fact, the best or copper pipe, but now no manufacturers have produced, mainly or cost!
This material can be seen, usually screen tube, that is, Bondi tube (iron pipe)It's plate-like or aluminium.Under normal circumstances can use 10 years, this is tested, while others are in the middle may be bad.
Now the refrigerator tube is using aluminum tube or Bondi tube (Bondi tube, that is galvanized steel pipe, in fact, the iron pipe, iron pipe above the paint once lost, it is easy to rust..)
