Copper is a relatively soft and malleable metal with excel-lent formability, making it ideal for architectural applica-tions such as roofs, wall cladding, gutters and downspouts.

The five-cent Jefferson nickel minted in 1973 is a round piece made of copper and nickel in a ratio of 3: 1. It comes with a plain edge and thickness of 1.95 millimeters (0.07678 inches). Like other nickels from the series, this one has a diameter of 21.21 millimeters (0.83505 inches) and weighs 5 grams (0.17637 ounces). Before 1965, United States nickels were composed of 75% copper and 25% nickel. This copper-nickel combination is still used today in the production of U. S. nickels. The Coinage Act of 1965 changed the composition of the nickel when silver was removed and instead replaced with more copper, meaning that all United States nickels issued since ...33 items ... 75% Copper - 25% Nickel.
