Copper is as it is strong and will last a long time, the only thing is it changes colour by weathering.
it does
copper because idk
gold
fhhjjf
Currently, it is a layer of copper pressed between two layers of an alloy of 91.67 percent copper and 8.33 percent nickel.
because electricity is not wasted
US dimes were composed of silver and copper. From 1796 to 1837 they contained .8924 % silver and .1076% copper. Starting in 1837 the composition was changed to 90% silver and 10% copper. This was used until 1964. In 1965 the composition was again changed to a core of pure copper with outer layers of 75% copper and 25% nickel. Some 90% silver dimes are still minted today for special coin sets only.
gold
Its around .030 thick.
fhhjjf
it is 7 layers
they probably and most likely will because i used to have layers that were just like that and i have really thick hair and i thought it looked really good and so did my friends.
A saw would be better - like a band saw
The resistivity of copper is very low and as the strip is so thick then resistance would be almost zero.
Quite Thin, As We Have 8 Layers Of Skin.
:D
One cell thick
the crust is the thickness of earths layers
Barton's Metal is copper overlaid with a thick layer of gold, and was used in 1825
