Gold. Gold is a pure metal that doesn’t rust because it doesn’t contain iron. “Gold is the most non-reactive of all metals and is benign in all natural and industrial environments. Gold never reacts with oxygen (one of the most active elements), which means it will not rust or tarnish.

Does gold react with iron
By now, you may know that gold is unlikely to react with oxygen in appearance and does not form flats on the surface like iron does, so it does not deteriorate.
Why gold do not get rusted
The metals as such and platinum are apparently not susceptible to corrosion as they are unaffected by clean air and most acids and are now more stable than many of their natural components such as oxides or sulfides. The lack of reactivity has led to them being called noble metals.
Does gold corrode other metals
Gold is one of the least sensitive elements on the periodic table. It does not react with oxygen, so the house will never rust or corrode. Water, air, bases, and any acids other than aqua regia (a mixture of hydrochloric and nitric acids), which can soften gold, often cannot affect gold.
Does gold oxidise
Pure gold does not interact with oxygen; However, a wide range of applications involves the use of metal alloys rather than pure gold. Gold alloys contain elements that move through oxidation. The more alloying elements contained in the gold alloy, the higher the likelihood of corrosion of gold.

How is cast iron different from pig iron How is pig iron converted into cast iron
CAST IRON IS PRODUCED FROM GRAVE IRON BY CASTING GRAVE IRON FROM SCRAP AND COKE AND INTRODUCING HOT DUT INTO THE MIXTURE. 3% CAST IRON HAS LESS CARBON CONTENT THAN CAST IRON. Cast iron is hard and brittle.
Does iron oxidize in water
Oxidation of iron When iron comes into contact with liquids and rusts from oxygen. As long as salt is present, such as in seawater or salt spray, iron is likely to rust faster due to electrochemical reactions. Golf iron The iron is relatively unaffected by a clean pond or dry oxygen.
