Aluminum appearing colors which may range from light gray to silvery white. Your intended use allows you to rank the characteristics of each grade from most important to least important. Stainless Steel: Stainless steel is a metal alloy made out of iron, chromium, and carbon. A 100-nm layer of aluminum or silver makes an excellent reflector for the visible spectrum. Sir Humphry made a bit of a mess of naming this new element, at first spelling it alumium (this was in 1807) then changing it to aluminum, and finally settling on aluminium in 1812. German silver and sterling silver may be the same color and have a similar shine and gleam, but that doesn't make them the same.
