110 Copper square bar is an excellent candidate for some processing techniques as well as both indoor and outdoor applications. When copper is exposed to natural elements, it will patina and develop a greenish or bluish hue over time. Commonly referred to as Electrolytic Tough Pitch Copper (ETP), copper alloy 110 has great corrosion resistance and conducts electricity. The material is non-magnetic with a semi-smooth surface and defined edges. Copper square bars are commonly used in corrosive environments, electrical work, mechanical or architectural applications, and ornamental projects. ASTM B187 110 copper is a standard specification for copper wiring, busbar, electrical power systems, and installations.
