We manufacture 70/30 Cupro Nickle Tube in all sizes, shapes, and dimensions keeping all international standards in mind. Our products have made their space in national and international markets because of their performance and our excellent customer-centric service policies. Our ability to innovate, create and design new products made us the flag bearer of modern manufacturing. Our courage to do experiments makes us unique and extremely efficient.

 70/30 Cupro Nickel is mainly preferred when the severity of service conditions (Cooling Water, Steam, Condensate, Temperature, etc.) is such as to virtually rule out all other copper metals. Due to its hardness and to the type of oxide whereby its surface is self-protected, 70/30 Cupro Nickel has excellent resistance to impingement and erosion-corrosion by suspended solids in sea water flowing at up to 3-3.5 m/s (10-11.5 ft /s).
 Like all Cupro-nickels, 70/30 Cupro Nickel is virtually immune from stress-corrosion cracking.  It can be very sensitive to deposit attack and is therefore not recommended for stagnant or slow-moving (under 1 – 1.2 m/s or 3.5-4 ft/s) water.

C715 copper alloy is also known as 70/30 copper-nickel, as it is comprised of 30% nickel. Copper nickel alloy 715 finds its greatest application in areas of high temperatures and pressures combined with high velocity and destructive turbulence. The small iron content, up to 0.5%, gives the C715 alloy an extraordinary resistance to general corrosion and stress corrosion cracking, making it very suitable and ideal for marine or industrial industries.
