What is SB111 C70600 material?

The SB 111 c70600 is a type of copper-nickel alloys which exhibits superior resistance to impingement attack. They are also highly resistant to SCC. This specification establishes the requirements for ferrule stock and a seamless tube of copper alloys of a specified range of diameters.

What is C70600 material equivalent to?

This copper nickel C70600has excellent corrosion resistance even in marine environments. Copper nickel 90:10 possesses average high strength and good creep resistance at high temperatures. Its equivalent DIN EN 2.0882 material also designates C70600.

Can copper-nickel rust?

A large reason for copper-nickel's corrosion resistance stems from the alloy's ability to form a complex surface film in response to the presence of seawater. The surface film protects the metal below, and gives the alloy a corrosion rate in seawater that is between 0.025 and 0.0025 mm/yr.

SB 111 C70600 chemical composition

The chemical composition of SB 111 C70600 (90/10 Copper-Nickel) is primarily copper (remainder), with 9.0% to 11.0% nickel. It also contains 1.0% to 1.8% iron, 1.0% zinc, and up to 1.0% manganese. Other minor elements include a maximum of 0.05% lead, and the total sum of copper and named elements must be a minimum of 99.5%.

SB 111 C70600 Mechanical properties

ASME SB111 C70600 is a 90/10 copper-nickel alloy whose mechanical properties vary significantly depending on its specific temper (heat treatment) and form (e.g., tube, bar, plate). Key properties include a wide range of tensile strength (from approximately 303 MPa to 414 MPa or 44 ksi to 60 ksi) and yield strength (from 110 MPa to 393 MPa or 16 ksi to 57 ksi). It also has a high elongation, good toughness, and excellent resistance to corrosion and biofouling.
