Aluminum is viewed as a precious metal

Is bronze a precious metal?

No. Bronze has an important precious metal property: It is very corrosion-resistant, so it hardly oxidizes. But only pure metals are considered precious metals - bronze, on the other hand, is an alloy. It consists of at least 60% copper (which is a semi-precious metal after all!) - the rest are other non-precious metals such as tin, aluminum or lead. Thus, by definition, bronze is not a precious metal. By the way, it is not nearly as valuable as gold or silver. For comparison: if a gold medal were made of pure gold (which it is not), it would cost 80 times more than a corresponding silver medal and 2,400 times as much as a bronze medal. But the price is not the decisive criterion for the term "noble", but the chemical properties.

“Real” precious metals are: silver, gold, rhodium, ruthenium, palladium, osmium, iridium, platinum. Mercury is also usually included. It is right next to gold in the periodic table, but it is more reactive and therefore an atypical precious metal.

If you look at the periodic table of the elements, a “copper medal” as “third place” would actually be more consistent, because: gold, silver, copper - these three metals are directly above one another. But copper is known to be relatively soft and pliable - not what you would expect from a stable medal. That was also the reason why bronze became so important in early history: This alloy of copper and tin is much harder and therefore more suitable for weapons than the pure copper that was known before.

(In an earlier version of the post, copper was mistakenly labeled a precious metal.)
