We are exporters of Copper Nickel Tubes or CuNi Tubes manufactured as per ASTM B466. Siddhagiri Metals and Tubes is a renowned supplier of copper nickel items with ISO 9001:2015 certification and recognisiton from many organisations around the wold.
We supply a full range of Copper Nickel seamless tubes used for high-performance gas chromatography (GC) and liquid chromatography (LC) as components for chromatography columns used for analytical and preparative processes in diverse industries. To separate in very small sample sizes for very complex mixtures, these analyzes can be highly accurate and precise. Samples can be used for all kind of materials such as; water, gases, fuels, air, foods, flavorings, pesticides, plastics, drugs, tissue extracts. 70 30 CuNi Seamless tubes are available in various sizes ranging from 1/8" OD TO 2"OD, 3MM OD TO 38 MM OD. The thickness of Copper Nickel tube ranges from 1MM TO 3 MM, 0.028 TO 0.156 IN. 70 30 CuNi tubes are available in Indian, European and Japanese origin.
Seamless Tube is made from a solid round steel ‘billet’ which is heated and pushed or pulled over a form until the steel is shaped into a hollow tube. Billets are procured both from indigenous suppliers and from abroad. We carry a wide range of CuNi tubes (ASTM B466), available in a variety of sizes and specifications, to be used in several industry for all kinds of high-temperature applications such as, thermocouple sheathes, burners, lance tubes, gas turbine, chemical processing, furnace equipment, jet engine combustion tubes, capillary tubes & heat exchangers.
Siddhagiri Metals and Tubes has exported Copper Nickel Tubes to many countries including Thailand, Indonesia, UAE, Japan, South Africa, Iraq, Iran, Saudi Arabia, Australia, Europe, Qatar, Malaysia, Congo, Brazil, Chile, USA, Canada, Japan, UK, etc

Properties of 70 30 CuNi alloy
70 30 Copper-Nickel Cold Forming and Hot Forming
With good hot and cold working properties, copper nickel alloy responds well to most fabrication processes. Due to properties inherited from Copper, Copper-Nickel alloy is can be easily drawn and spin.
70 30 Copper-Nickel Machining
Copper-nickels can be cut using most conventional cutting processes. Plasma-arc cutting is fast, accurate and economical. Laser and abrasive water jet cutting are also possible The machinability rating of 70 30 copper-nickel alloy is 20%.
70 30 CuNi Welding
Copper Nickel Alloys can be easily joined by soldering, brazing and a variety of welding methods such as gas shielded arc welding, spot welding, coated metal arc welding, butt welding, seam welding, brazing, soldering and oxyacetylene welding processes.
70 30 CuNi Corrosion Resistance
Copper-nickel Alloys have good resistance to chloride pitting and crevice corrosion. They have excellent corrosion resistance against moisture, non-oxidising acids, alkalis and salt solutions, organic acids and to gases such as oxygen, chlorine, hydrogen chloride, hydrogen fluoride, sulphur dioxide and carbon dioxide. It is found that the corrosion rates of CuNi alloys are 0.02-0.002mm/year in sea-water.
