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.
Aluminum has a higher thermal conductivity than steel. This means that aluminum is better at conducting heat compared to steel.
Steel has a lower thermal conductivity compared to aluminum. This means that aluminum is better at conducting heat than steel.
From a chemical standpoint, steel is a better thermal and electrical conductor than aluminum. Practically, however, aluminum's usefulness as a conductor is limited by its ease of oxidation. Since aluminum oxide greatly diminishes the conductivity of the aluminum over time, aluminum is not very suitable for use as a conductor in practical applications.
Some other metals commonly used to prevent rusting include stainless steel (which contains chromium), aluminum, and galvanized steel (which is coated with a layer of zinc). Copper and nickel can also be used for certain applications.
It depends on the environments. If the two materials will be in contact with water or high humidity then you can have some corrosion on the galvanized steel.Stainless steel and galvanized steel can corrode. However, galvanized steel will corrode at a higher rate. Stainless steel is more corrosion resistant than galvanized steel, but in some circumstances it will also corrode.
galvanised steel is a lot more safer....... if u go by the book.... it is upto 10 times stronger than stainless steel in aluminum
Stainless steel is much better than galvanized for use as a zip-line.
Galvanized steel is better for plumbing in a bathroom sink. It lasts a lot longer than PVC.
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.
Aluminum would be better at keeping the temperatures lower compared to steel.
Aluminum has a higher thermal conductivity than steel. This means that aluminum is better at conducting heat compared to steel.
Steel has a lower thermal conductivity compared to aluminum. This means that aluminum is better at conducting heat than steel.
Aluminum is not as good a conductor of electricity as copper or silver, but it is better than steel. Aluminum's conductivity is around 61% that of copper, whereas steel's conductivity is much lower. Therefore, aluminum is a more suitable choice than steel for conducting electricity, especially in certain applications where weight and cost are considerations.
aluminum conducts heat better than stainless steel.
Stainless steel would last you much longer than aluminum. Aluminum is not as dense as steel, and may not last as long.
Zinc is the coating on the steel that makes it galvanized.
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.
