Detail Fact on UNS C70600 Alloy


UNS C70600 Alloy

C70600 copper nickel alloy is an excellent choice for marine applications because of its high corrosion resistance and low macro fouling rates. It also has good ductility and toughness. UNS C70600 ASTM is a copper-nickel alloy that contains 90% copper and 10% nickel. It is commonly used in the manufacture of piping for a variety of industrial and marine uses.

Chemical Composition

UNS C70600, also known as copper-nickel 90/10, is an alloy of 90% copper and 10% nickel. It is a corrosion-resistant grade used in various applications. It has excellent ductility, strength and formability. It is a popular grade for marine and industrial applications due to its high ductility and toughness. It is also resistant to abrasion and scuffing.

The chemical composition of uns c70600 ASTM includes 90 percent copper and 10 percent nickel with a small amount of iron and manganese. It is annealed at temperatures between 593 to 816 deg C (about 1100 to 1500 deg F). Weldable and ductile, UNS c70600 ASTM is used in the manufacturing of piping for a variety of purposes. It is also used in the fabrication of heat exchangers and cooling plants.

Mechanical Properties

Mechanical properties are the physical characteristics of a material that determine how it can transmit forces and resist deformations. They are an important factor when choosing a material for an application or industrial project.

There are many different types of tests that can be used to test the mechanical properties of a material. Some can provide multiple properties at once, while others are more specific and can only tell you about a single property, such as hardness or toughness.

For example, a tensile test will tell you the ultimate tensile strength of the material as well as information about its yield strength and modulus of elasticity. The stress-strain curve generated by the tensile test can also reveal some of the other properties of a material, including its ductility and malleability.


UNS C70600 (CuNi 90/10, cupronickel) is a nickel-chromium alloy with supplemental amounts of copper, iron, and molybdenum. It has excellent corrosion resistance and formability in both heat and cold environments. It is used for piping in power generation, oil and gas, petrochemical and marine engineering.

UNS c70600 ASTM is resistant to both chloride and sulfide stress-corrosion cracking in seawater. It can be used in areas where stainless steel is not allowed because of this problem. It is also used in machined and forged valve and pump components, fittings and hardware.

Moreover, UNS c70600 ASTM has low uniform corrosion rates resulting in thinner walled pipe systems with significant weight saving. It is also resistant to bio fouling and does not reveal sensitive corrosion potential variations under different seawater conditions, such as chlorination and increased seawater temperatures.
