Copper Nickel UNS C70600 Chemical Composition Properties, Grade, Chart and Document

ASTM B466 C70600, the standard specification for seamless copper-nickel pipes and tubes designed for general corrosion-resisting and elevated-temperature applications, is considered one of the most widely recognized global standards for this product. It takes alloy C70600, which is a cupro-nickel alloy, as its base content (90% Coper, 10% Nickel). This alloy is constituted by high percentage (10%) nickel and a low percentage of copper (90%), thus providing great corrosion resistance in marine and fast rivers conditions. Chemical composition generally includes low rates of those substances like iron, manganese. ASTM B466 contains the minimum mechanical and physical properties, dimensions, tolerances, and testing requirement for tubing. This standard ensures constant quality and performance in different areas of application such seawater pipeline system, cooling and heating heat exchangers, condensers and desalination plants. For the purpose of detail explaining of chemical composition, grades, and charts do ASTM B466 standard documentation or downloadable PDFs from relaible sources where you can find them.

C70600 Coppers Chemical Composition And Grade Table

From all other types of copper, C70600 copper which is also known as 90/10 copper-nickel is distinguished by its excellent resistance to corrosion in seawaters environments. The chemical composition will normally be 90 percent copper and 10 percent nickel plating which renders it highly resistant to seawater corrosion & bio-fouling. The tables of grade C70600 copper clearly show its many grades and the corresponding properties which help in the selection of the right alloy from a broad marine industry range which include heat exchangers, condensers and piping systems.

The Advantages and Disadvantages of ASTM B466 C70600 Copper Material Properties, C70600 Properties

    Advantages:

  • Excellent Electrical Conductivity: OFE Copper C70600 demonstrated remarkable electrical conductivity, which allowed it to be employed for applications that demanded transmission with minimum energy loss by means of electricity.

  • Soft Material: Besides serving as a paramount feature, the material's natural softness provides a user-friendly working experience during the shaping, bending, and shaping phases without the need to sacrifice physical strength.

  • High Thermal Conductivity: C70600 delivers a great thermal conductivity performance, which makes it a perfect option for various heat transfer applications - heat exchangers, radiators and so on.

  • Good Corrosion Resistance: Although as reliable as other copper alloys, C70600 is not that corrosion resistant still offering good protection against environment wear.

  • Susceptibility to Oxidation: As a matter of fact, OFHC C70600 is subject to oxidation, which occurs when it comes in contact with air or moisture, as a result of it being highly pure. Hence, it requires proper handling and storage methods.

    Disadvantages:

  • High Cost: Oxygen-free copper (OFC) is often more expensive (is almost always a higher price) than the other copper alloys (for example, and something like C70600) because of its added purity and composed through of a specialized manufacturing process.

  • Limited Strength: Longevity of the C70600 material component shall be affected by its softness, and so it may have applications where the greatest mechanical strength is not needed.

  • Not Ideal for High-Stress Environments: Construct a sentence that indicates the low strength and the susceptibility to oxygen is undesirable for the heavy load bearing purpose.

  • Limited Work Hardening Ability: C70600 copper, which lacks large workplace capacity, only does not essentially improve in strength or toughness, through bending or hammering, for example.

  • Susceptibility to Stress Corrosion Cracking: However, Wrought Copper C70600 proves to have a good passive layer that helps to prevent corrosion. The SCC can limit the distribution of this material under specified conditions.
