CuproNickel Products
High-performance CuproNickel tubes engineered for marine, offshore, and industrial heat-transfer systems with excellent seawater corrosion resistance.
70/30 Tubes
Tube Tech® manufactures top-grade Cupro-Nickel 70/30 tubes engineered for extreme corrosion resistance in high-velocity and high-turbulence seawater environments.
The 70/30 alloy delivers higher mechanical strength and superior resistance to stress-corrosion, making it the preferred material for critical marine heat-transfer equipment.
