Galvanized steel. It lasts longer and is less affected by chemicals and saltwater if you choose to go that route. I do suggest saltwater. It needs for less maintance than a pure chlorine pool.
Go with the aluminum if you can afford it.
Aluminum does not rust.
It depends on what you want to do with it. Galvanisation usually involves zinc anyway.
Aluminum is not the best material for a garden trowel, while very light, it is too soft. A better material would be steel or even better stainless steel.
It really depends on the purpose, Aluminum is lighter (depending on the thickness) and will not rust (Nonferrous). However Galvanised steel is cheaper normally, as it is just a coat of zinc on steel, the only problem is that if it gets scratched enough to take away the zinc coating, then it will corrode just as fast as normal steel. Both have similar enough strength though. It mostly just depends on what you are wanting to do.
The walls of some above ground and some inground vinyl liner pool kits are made of aluminum.
Galvanized steel is better for plumbing in a bathroom sink. It lasts a lot longer than PVC.
Stainless steel is much better than galvanized for use as a zip-line.
Inground vinyl is better, their is less exposed part to the oxigene, therefore, last longer.
The simple answer is that the case in question is made of 24 gage galvanized high carbon steel. SGCC is a galvanized high carbon steel. It is Harder than typical steel, and has a thin coating of electro-statically bonded zinc that prevents it from oxidizing. the 0.6mm is the thickness of the metal being 6 tenths of a millimeter also known as 24 gage steel. As a computer case material it is slightly heavier and significantly strong than Aluminum and plastic, provides better heat management than Plastic, but not as good as Aluminum. it is usually only used in the frame of a computer case to hold the internal components, however it also can be used to make the side panels. Sorry for replacing the original answer in its entirety but it was incorrect.
Depends on what you consider better? If a bladder fails you need to rush out and get a new one if a galvanized tank gets floooded you can drain it and your back in business
It flows through aluminum foil better because electricity flows throw aluminum or metal better then plastic or other
