Should be harder to scratch than gold
Mixing iridium with gold can create a stronger and more durable alloy, suitable for high-wear applications like jewelry or electronics contacts. However, it can also increase the alloy's hardness, making it more challenging to work with during manufacturing processes. The addition of iridium may also impact the color of the gold, potentially creating a unique and distinctive hue.
Iridium and gold can be mixed by melting them together at high temperatures using specialized equipment. This can create an alloy of iridium and gold with properties that depend on the ratio of the two metals in the mixture.
No, gold is around twice more expensive than iridium.
Iridium mingles with gold, but for what reason, hardening?
When iridium, oxygen, and nitrogen are mixed together, they do not react to form a specific compound. Iridium is a noble metal and does not readily react with oxygen or nitrogen under normal conditions.
