C11000 (ASTM B152) Alloy Data Specifications

Copper, such as the roofing on a house or that found on kitchen pots is likely what comes to mind when we hear the word that describes this elemental metal. While copper or C110 is the most commonly available copper product it often finds application out of sight where we depend on it most, such as motors in air conditioning units or the electric meter that connect houses to the electric grid. Refined electrolytically to reduce impurities levels, C110 is 99.90% pure copper and offers excellent electrical and thermal conductivity.
