Farmer’s Copper Ltd. maintains an extensive inventory of C12200 DHP copper in sheet, plate, pipe, tube and fittings. C122 is commercially pure copper, which has been deoxidized with phosphorus, leaving a relatively high residual phosphorus content. Copper alloy 122 is not susceptible to hydrogen enbrittlement, but has relatively low electrical conductivity due to the amount of phosphorous content.

Typical applications of C12200 DHP

  • Distiller/Brewery Tubes
  • Heat Exchanger Shells
  • Expansion Joint Tubes
  • Kettles
  • Condenser Tubes
