Gold is malleable because it is a soft metal. It is used for:
- It is a good conductor of heat and electricity, and is unaffected by air and most reagents.
- It is used in coinage and is a standard for monetary systems in many countries.
- It is also extensively used for jewelry, decoration, dental work, and for plating.
- It is used for coating certain space satellites, as it is a good reflector of infrared and is inert.

gold, in it's pure form is a very soft metal. Thus the biting of the coin in the past to make sure it was real. Gold and Silver is the basis for many monetary systems in economic and governmental world. Because gold is seen as money it is used in numberous ways to display wealth as so called "bling". Although gold was the money system of the past and current, the globe is quickly transfering to titanium and other alloys that are used in tecnological formats.
Gold is also a great conductor for electricity and electronic information. The future of computer chips and boards will soon see gold in the chips instead of copper as is the standard right now. Once humans develop a way to transit data quicker, gold will be the conduit for this faster information as the informational pulses can go that fast with the gold conduits.

Gold, when used with copper, gives it strength. 24 ct is the purest form. Karat determines the amount of copper in % added.
So, a 22 ct. will be 22/24 = 91.67% pure or, one can say 8.33 grams of copper is added to every 100 grams of gold.
It is melleable in its pure form (24 ct). One can easily press it between their fingers with a thumb like a bread dough. More copper it has, the harder it gets and it will be easy to work with using machines. So, a 10 ct gold jewellery is made by machines. A 22 ct gold jewellery is made by skilled artisans, by hand.
Gold never, NEVER tarnishes, thus making it the most preferred metal by many people for thousands of years. It is also rare. So, it is expensive.
Roman empire used it like currency. Centuries ago, many countries were using gold this way.

Pure gold is malleable because it's naturally a soft metal and isn't mixed with other hard alloys, like aluminum.
Lol, it's used for jewelry, of course! =P

I don' really know what it is used for besides the obvious, jewelry. The reason I think it is so malleable is because it has a low specific heat.
