Gold Alloy Zinc, copper, nickel, iron, cadmium, aluminium, silver, platinum and palladium are all common metals alloyed with gold. Gold and copper are the only two coloured pure metals. Gold is yellow and copper is a reddish brown.

Are gold alloys harder than pure gold?

Gold alloys are used in a wide variety of applications. Alloys below 14 karats are susceptible to stress corrosion cracking. Common gold alloys, including Au–Ag, are soft and malleable. Gold–copper alloys are harder, more fusible, and have higher tensile strength than does pure gold.

Why is most jewelry and alloy and not pure gold?

There is a reason why 24K gold is not widely used in jewelry and it has to do with the physical properties of the metal. Gold is very soft and any piece made solely of it will bend easily. This is why gold is mixed with other metals, which make the resulting jewelry more durable (and also cheaper).

Which is a stronger metal, pure gold or alloy?

Often gold is made into an alloy by mixing it with other metals in order to create a stronger metal than pure gold. These alloys are often cheaper than pure gold as the carat (the measure of the purity of the gold) decreases.

What’s the difference between pure gold and colored gold?

Colored gold alloys are just as “real” as their golden colored counterparts. Pure gold is generally too soft to be used for jewelry, so other metals are nearly always added to it, no matter which color of gold is being prepped for jewelry making. The designations 18 kt, 14 kt, or 10 kt indicate how much pure gold is present in the mix.

How are alloys and karats of gold created?

Alloys are created by mixing different metals with the pure gold to create a stronger version of itself. Karats of gold are created by mixing different ratios of metals. 14k gold is incredibly durable containing 58% pure gold. 18k gold is also strong but quite not as durable since it contains 75% pure gold.

Are there any downsides to wearing pure gold?

The downside of pure solid gold is that is a very malleable and soft and is therefore not recommended for jewelry intended for everyday wear. Often gold is made into an alloy by mixing it with other metals in order to create a stronger metal than pure gold.
