Friday trivia: Copper

For a while, we have been writing little trivia notes on our Facebook page.  We thought we would start posting them on our blog so more people can enjoy it.  

Today's post is on copper.

        Did you know???

Copper was used over 10,000 by humans, making it one of the first metals used.
 
Copper is one of the few metals that occur naturally in a pure form.
 
Copper is by far the best low-cost conductor of electricity and heat---so it is used for electrical cables as well as the bases of pans. 

Copper + Nickel = cupronickel
Copper + tin = solder
Copper + tin = bronze
