How long, over what distance, can an once of pure gold be stretched?
Gold has for a long time been a metal the properties of which have made it so appealing to people that it has been the reason behind hundreds of wars over the centuries. Some of the properties of gold that make it a very unique metal include its inertness, its beauty and the hundreds of industrial applications it has. Many of these have to do with the fact that gold is the metal which has the highest ductility and malleability.
The extremely high ductility of gold allows a wire that is 3.2 km long to be drawn from just one gram of gold. So the length of wire that can be drawn using an ounce of gold would be approximately 91 km.
A 91 km long wire can be drawn with 1 ounce or 28 grams of gold.
