Most alloys of gold are stronger than pure gold because pure gold is very soft. A lot of jewelry applications that use gold use an alloy because it's cheaper (for one) but is stronger. You will not find a Tiffany set in pure gold because it isn't strong enough to hold the stone up and away from the band with just a few small mounting thingies.

Why is a ring made from an alloy rather than pure gold?
Because pure gold would not hold the ring's shape. Pure gold is soft.
Which is more expensive white or yellow gold?
Pure yellow gold is more expensive than an alloy.
Is gold a soft or hard metal?
gold can be both soft and hard depending on how pure it is, pure gold (24K) is softer than a gold alloy. And the lower the number the harder it is. 10K is harder than 14K, 14K is harder than 18K, and 18K is harder than 24K (pure gold).
Is white gold as expensive as yellow gold?
White gold is an alloy of gold and at least one white metal, usually nickel or palladium. Like yellow gold, the purity of white gold is given in carats: 24 kt is pure gold, 18 kt has 18 parts gold and 6 parts of another metal, so it is 75% pure.Since nickel is cheaper than gold this white (alloy) gold is cheaper than the yellow pure variant. The price of palladium is unknown to me, so I can't figure it out.
What is 10 k gold made of?
10 karat gold is made of gold and different alloys. Ten karat gold is the only gold that has more alloys than it does pure gold, which makes 10 k gold stronger than gold with less alloys.
Why is a ring made from an alloy rather than pure gold?
Because pure gold would not hold the ring's shape. Pure gold is soft.
Why are aroplanes made from aluminum alloy rather than pure aluminum?
Pure aluminum is not strong enough as building material for airplanes. Alloy with Al are stronger.
What are the benefits of this alloy compared to pure jewelry?
An alloy can sometimes be much stonger than the pure substance. For instance, pure gold is quite malliable and can be crushed very easy.
Which is more expensive white or yellow gold?
Pure yellow gold is more expensive than an alloy.
How hard is gold?
Gold can be both soft and hard depending on how pure it is, pure gold (24K) is softer than a gold alloy. And the lower the number the harder it is. 10K is harder than 14K, 14K is harder than 18K, and 18K is harder than 24K (pure gold).
Is 18 karat gold better than 9 karat?
24K is pure gold. Any number smaller than that means less gold and more alloy metals. Alloy metals are mixed with gold to make it harder. Pure gold would be so soft that it would deform or get scratches and nicks in it.
Give an example of an alloy and tell how it's properties may make it more useful than a pure metal?
An alloy is less reactive and much stronger, instead of using a pure metal it may be reactive and weaker.
Is gold a soft or hard metal?
gold can be both soft and hard depending on how pure it is, pure gold (24K) is softer than a gold alloy. And the lower the number the harder it is. 10K is harder than 14K, 14K is harder than 18K, and 18K is harder than 24K (pure gold).
Why are metal things often made of alloy rather than pure metal?
Alloys allow certain metals to be stronger, or lighter, or both
Would you rather have lower carat gold or higher carat gold?
lower carat gold is great if you want your gold ring to be stronger...the downside is there is less gold. Because gold is a soft metal, it is usually paired with some alloy to make it stronger. The higher carat gold rings have more gold composition than alloy thus making them weaker but more pricy because there is more gold.
Why a metal alloy behaves differently to a pure metal?
A metal alloy behaves differently than a pure metal because the different chemical properties of the metals in an alloy both contribute to the alloy's properties. Certain alloys may be stronger than the original metals because one metal may fill a "gap" in the other's structure. Of course, other properties besides strength are also changed in an alloy.
