Material
Copper
Known for its reddish color and greenish hue after oxidization, copper is a tough metal with very high thermal and electrical conductivity, and low chemical reactivity. It offers good definition, making it a popular choice for small, robust and decorative models such as coins, medals, connectors, or statues.
