Copper Nickel 90/10 Tube

Copper nickel 90/10 tube What is a copper nickel 90/10 tube?

These tubes comprise 90% copper and 10% nickel, delivering top-notch corrosion resistance in marine environments. A copper nickel 90/10 tube also has small amounts of iron and manganese, boosting its tolerance for abrasion. Manufacturers produce 90/10 cuni tubing with stricter dimensional tolerances than pipes.

Another sector relying on these components is hvac or heating, ventilation, and air conditioning. A 90/10 copper nickel hvac tube is highly coveted for its thermal conductivity.


What are the common applications of copper nickel 90/10 tubes?

Marine industries benefit from these sturdy, durable tubes. For example, a 90 10 copper nickel tube works in seawater pump components and valves. Clients in chemical processing, offshore applications, and sanitary environments like hospitals also employ this material for its anti-microbial properties. A cuni 90/10 heat exchanger tube, evaporators, and condenser plates are popular.
