Copper Nickel Alloys Grades 70/30, 90/10 we supply - Technoforge Pipe and Fittings has been created to promote and distribute for the worldwide shipbuilding and offshore industries copper nickel pipes and fittings.
We have access to many grades in Copper Nickel and the following are just two of the general grades available. Please contact us for any specific grade you require.
Copper Nickel 90/10 is the most commonly used wrought copper alloy for marine engineering and can be found in seawater systems for naval, commercial shipping and the oil & gas markets due to its good strength, corrosion resistance and inherent resistance to biofouling in salt water environments. Randhir Metal offers the full spectrum of product types in this alloy including pipe & fittings in both Metric and EMMUA size ranges catering for all applications. Comprising 90% copper and 10% nickel, this grade also has small additives of iron and manganese which enhances its corrosion resistance.
Together with a high ductility and toughness puts this in high demand for more standard uses in the marine, chemical, offshore and petrochemical industries. Within this grade, popular specifications include C70600 and CN102.
This is a 70% copper and 30% nickel alloy grade which has added iron and manganese. It is used for more demanding applications than 90/10 material. It is resistant to corrosion and offers increased strength over 90/10. Copper Nickel 70/30 is stronger than the more common copper nickel 90/10 and is able to withstand corrosion at higher velocities in marine applications, making it the favourable choice in submarine systems. Randhir Metal carry the India's largest range of product in this alloy and are the only stockholder of DEFSTAN-02 879 metric tube specification released for use on UK naval vessels. The most popular specifications covering this alloy are CN107 and C71500 designations. The naval specification, NES 780 (or DEFSTAN -02-780) gives tighter controls on impurities and mechanical properties along with a required impact value. Used for marine flanges and fittings, valve bodies, pumps, chemical engineering components.
