iSteel makes, trades and tolls a broad assortment of Cupronickel 70/30 Pipes & Tubes to its customers worldwide. We design and develop each one of our goods in a high-end infrastructure. Our highly equipped inventory ensures the top-notch quality and durability of our products. Cupronickel 70/30 consists of 90% Copper and 10% Nickel. It contains iron and manganese that upgrade the general nature of the Alloy. Cu 70/30 is used for marine, chemical, petrochemical, shipbuilding and other applications inferable from its flexibility.
70/30 Pipes & Tubes contradict hydrogen embrittlement and hold their mechanical properties even at cryogenic temperatures. Our Cupronickel 70/30 offer sensible quality and strength at lifted temperatures. Also called UNS C71500, these Cu70/30 Pipe & Tubes offer astounding oxidation resistance in soaked air and steam. We build a product line that is highly sustainable and offers maximum utility.
