Sunraj Industries manufacture, exports and supplies 90/10 Cupro Nickel Tube which have excellent resistance to corrosion in sea water. Besides this, these tubes have high resistance to corrosion and air impingement. Cupro Nickel Tubes have good strength and ductility at ordinary temperatures and relatively high strength at elevated temperatures.
90/10 Cupro Nickel Tubes which are widely used in condensers, coolers, Power Plants, Ship Building & Ship Repairs, and heat exchangers as well as marine applications. These Cupro Nickel Tubes are produced by Sunraj Industries in a wide range of OD (outer diameter), wall thickness and temper conditions.
