Copper EDM

In its elemental form, copper is soft, shiny and highly malleable. Due to its soft nature, it is most often used as an alloy and is one of the most electrically conductive of all the metal elements. Copper is one of a few metallic elements with a natural color other than gray or silver. Pure copper is orange-red and acquires a reddish tarnish when exposed to air. Copper has extremely good electrical conductivity, thermal conductivity and corrosion resistance. Copper is also used in buildings, usually for roofing, and oxidizes to form a green verdigris (or patina).
 

Physical Properties of Copper EDM

The physical copper properties that make this element unique include the following:

• Toughness - Copper may not be strong, but it is not easy to break due to its high toughness. This property comes in handy for piping and tube applications, where a rupture can be dangerous and expensive.
• Strength - Copper is a weak metal with a tensile strength about half that of mild carbon steel. This explains why copper is easily formed by hand but is not a good choice for structural applications.
• Conductivity - Second only to silver, copper is not only an excellent conductor of electricity but also of heat. As a result, copper serves well in applications such as cookware, where it quickly draws heat to the food inside.
• Ductility - Copper is very ductile and very malleable. The electrical and jewelry industries benefit from the ductility of copper.
