Copper Nickel Tubing
Farmer’s Copper Ltd. inventories Copper Nickel C70600 (90/10) and C71500 (70/30) tubing. Copper Nickel, also known as cupro nickel or CuNi, has proven to be very resistant to seawater, brine water, organic compounds, salts, diluted non-oxidizing acids, and more. Due to its complete resistance towards marine organisms such as barnacles, Copper Nickel tubing is commonly used in seawater piping systems.
Farmer’s Copper Ltd. established in 1920, is committed to achieving the goals set by our customers. We also maintain additional inventory of copper nickel in plate, bar, pipe, flanges and more.
