Hari om,you are asking a question as to : “ What is the difference between hard -anodized aluminium and stainless steel?”. Hari om.
Hard anodized aluminium can be coloured, dyed, sealed. Its aesthetic appearance can be improved at a very nominal cost. Initial investment for aluminium anodized articles is also substantially less.
On the other hand, stainless steel is costly, can not be coloured by anodising. But can last for life time.

I imagine you might be wondering about pots and pans, and possible health effects, or maybe a comparison in effectiveness for cooking.
They are different materials:
Aluminum is considered stainless because the oxide or “rust” molecules line up nicely with the aluminum atoms below. So they do not flake off, instead they provide a very thin protective coat that prevents it from rusting further.
Hard anodized aluminum just means the metal was treated in a way that let oxygen get deeper into the surface creating a thinker coast of oxide (an electrochemical process). This means a lower chance that food cooking on it will react with the aluminum under the surface.
Steel makes a red oxide or “rust” where oxygen binds to the iron atoms. The molecules are larger and do not line up with the iron atoms, so it flakes off.
Stainless steel has other atoms like chromium added, since chromium oxide will form on the surface, and similar to the case above, the atoms line up so that they provide a protective coat.
Health
Iron is pretty safe. In fact, we require it. We have a lot of it in our blood. So trace amounts getting into our food are usually not a health concern. Some people are concerned about links between higher levels of aluminum and Alzheimer’s, but it appears that there is no definitive evidence, and the amount of aluminum you might get from cookware is negligible ( Aluminum and dementia: Is there a link )
I would be more concerned with Teflon and other non stick cookware that use more complex molecules to give a non-stick surface. Avoid those when you need to cook at a higher temperature, since they can break down and release toxic chemicals into the air. Avoid pre-heating these pans for more than a minute, or letting them get over 500 F. ( Nonstick Worries? )
Performance
Aluminum is a better conductor of heat (compared to steel), but it is not necessarily better. I think this article can do a better job comparing them than I could:

Hard anodized cookware is essentially aluminium cookware that has been bonded together with a nonstick coating using an electrochemical technique. This cookware is 30% tougher than stainless steel, making it incredibly long-lasting. Stainless steel is a kitchen-friendly, low-maintenance alternative. Hard anodized cookware, on the other hand, is a superior heat conductor and can produce outstanding cooking results.
