Apr 24, 2015That one oxide of a metal (There are three different Iron oxides with various amounts of oxygen in them) is harder than the metal does not mean that another oxide is harder than the corrsponding metal. All elements do not behave in the same way. Aluminium has a lower melting point than Iron Thus the can melts but Iron turns into oxide.

Zinc and Cadmium   University of Denver

Zinc and Cadmium University of Denver

Zinc, however, gives excellent protection against the weather and moisture, so it is preferred where this is important, since it is cheaper. Zinc protects the iron by cathodic protection, since it is higher on the electrochemical scale than iron and will sacrifice itself to protect the iron, reducing it to the metal and eliminating rust. This phenomenon was noted by Faraday in 1829.

Full Answer. Meteoric iron is a natural alloy of iron and nickel, and is the first alloy used by humans. Meteoric iron is the metal component of meteorites; the iron and nickel combine into an alloy due to radioactive processes in space. Another example of a naturally occurring alloy is electrum, a natural alloy of gold, silver and copper.

Why is zinc better at galvanizing iron than other metals

Why is zinc better at galvanizing iron than other metals

Apr 22, 2017The molten zinc wets or bonds chemically with the steel by forming 4 different layers made of different steel zinc combinations, the top being zinc and each layer below with a greater amount of iron. The layer next to the steel is the hardest and harder than the steel it is protecting which means the rust protection wont scrape off easily.
