Chhajed Steel & Alloys Pvt.Ltd is well-known manufacturers & exporters of Copper Nickel (Cu-Ni 70 / 30) Pipes and Tubes of high quality. Our raw material is of premium quality. We make sure that our products provide the highest durability. Cupro Nickel UNS C71500 70/30 Pipes are consistent in performance even in marine applications. 70/30 Cupro Nickel has excellent resistance to erosion-corrosion. 70/30 Cupro Nickel is virtually immune from stress-corrosion cracking.

It is not recommended for stagnant or slow moving (under 3.5-4 ft/s or 1 – 1.2 m/s ) water as it is prone to deposit attack. Readily weldable nature and passivity to stress corrosion makes Cu-Ni 70 / 30 a popular choice. Cupronickel is also resistant to crevice corrosion, biofouling, stress corrosion cracking and hydrogen embrittlement. Some of its applications ae as follows :

  • sheathing for wooden piles
  • underwater fencing
  • silver-plated cutlery
  • >cabled tubes for hydraulic and pneumatic lines
  • jewelry
  • tubes for light-duty condensers
  • tubes for feedwater heaters
