text: The criteria by which copper and copper alloys are selected for architectural projects include color, strength, hardness, resistance to fatigue and corrosion, electrical and thermal conductivity, and ease of fabrication. Appropriate thicknesses and tempers for specific applications are essential; substitutions can lead to inadequate performance.
  Architectural copper is generally used in sheet and strip. Strip is  or less in width, while sheet is over  in width, up to  in width by  in length, plus in coil form.
