Deoxidized High Phosphorus (DHP) Copper
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 relatively high residual phosphorus content. Copper alloy 122 is not susceptible to hydrogen enbrittlement, but is relatively low electrical conductivity due to the amount of phosphorous content.
Typical applications
- Distiller/Brewery Tubes, Plumbing
- Heat Exchanger Shells
- Kettles
- Condenser Tubes
- Medical Gas-Oxygen lines
- Gaskets
