What Is: C110 Copper

What is C110 Copper?

C110 Copper, known as electrolytic tough pitch (ETP) copper, boasts a minimum copper content of 99.9% and displays a vibrant reddish-orange hue. With its exceptional malleability, this material can be easily shaped and manipulated, making it an ideal choice for intricate designs in jewelry and decorative metalwork. The non-magnetic nature of C110 Copper ensures its compatibility with sensitive electronic components in functional art pieces. Over time, this metal naturally develops a patina, lending a unique character and depth to the appearance of the finished work. The combination of excellent electrical and thermal conductivity, corrosion resistance, and ease of fabrication make C110 Copper a preferred material for those working with metals in creative applications.
