The Egyptians and mesoamerican cultures were using platinum that far back. It’s extremely corrosion resistant.

They used an alloy called Electrum which has both gold and silver, twenty-six hundred years ago.

Thought about carbon fiber, but not. LOL

@ragingloli those are from a few hundred years in the future, not couple thousands years ago.

Gold and platinum are the gold standard, because while they oxidize, their oxides break back down to the free metal, so they are found as free metals in the wild. Highly oxidation resistant metals (slow reactors) include mercury, rhodium, palladium, tantalum, niobium, zirconium, vanadium, titanium, nickel, and molybdenum. Happy alloying.
