CarTech Ni-Cu 400 is a solid solution binary alloy combining high strength (comparable to structural steel) and toughness over a wide temperature range with excellent resistance to many corrosive environments.

CarTech Ni-Cu 400 has been used at temperatures up to 800°F (427°C) and as high as 1000°F (538°C) in sulfur-free oxidizing atmospheres. It also displays excellent mechanical properties at sub-zero temperatures since it does not undergo a ductile-to-brittle transition even at such temperatures.

This alloy is strengthened by cold work and is readily fabricated.

Applications:
CarTech Ni-Cu 400 has been widely used in many applications. It has been found particularly useful in marine and chemical processing environments.

Typical applications have included valves and pumps, pump and propeller shafts, marine fixtures and fasteners, chemical processing equipment, gasoline and fresh water tanks, crude petroleum stills, process vessels and piping, boiler feedwater heaters, heat exchangers, and deaerating heaters.
