ASTM B122/B122M C71500 Copper Alloy Plates: A Comprehensive Guide by ASC LLP

At ASC LLP, we pride ourselves on being one of the leading manufacturers, exporters, and suppliers of high-quality Copper Alloy ASTM B122/B122M C71500 Plates. Our plates are renowned for their exceptional durability, corrosion resistance, and superior mechanical properties, making them ideal for a wide range of industrial applications.

What are ASTM B122/B122M C71500 Copper Alloy Plates?

ASTM B122/B122M C71500 Copper Alloy Plates, commonly known as Copper-Nickel 70/30 plates, are specialized metal plates composed primarily of copper (around 70%) and nickel (around 30%), with small additions of iron and manganese to enhance their strength and resistance to corrosion. These plates are standardized under the ASTM B122/B122M specification, which covers the requirements for copper-nickel, copper-silicon, and copper-zinc alloy plate, sheet, strip, and rolled bar.

Copper Alloy C71500 is particularly well-suited for marine applications due to its excellent resistance to seawater corrosion, including both pitting and crevice corrosion. This makes it a preferred material in the shipbuilding industry, as well as in desalination plants and offshore oil and gas platforms.

Properties of ASTM B122/B122M C71500 Copper Alloy Plates

Copper Alloy B122/B122M C71500 Plates are distinguished by their unique combination of properties:

  1. Corrosion Resistance: One of the most notable properties of C71500 plates is their outstanding resistance to corrosion, particularly in marine environments. The presence of nickel enhances this resistance, making these plates ideal for use in saltwater and other aggressive environments.
  2. Mechanical Strength: The addition of nickel also contributes to the mechanical strength of C71500 plates, ensuring that they can withstand high pressures and stress, making them suitable for use in demanding applications.
  3. Thermal Stability: Copper Alloy C71500 maintains its mechanical properties even at elevated temperatures, making it an excellent choice for heat exchangers and other high-temperature applications.
  4. Weldability and Fabricability: These plates are easy to fabricate and can be welded using most common welding techniques. This makes them versatile and convenient for use in various industrial processes.
  5. Low Biofouling: C71500 plates exhibit a low tendency for biofouling, which is the accumulation of microorganisms, plants, algae, or small animals on wetted surfaces. This property is especially valuable in marine environments, where biofouling can be a significant issue.

Advantages of Using ASTM B122/B122M C71500 Copper Alloy Plates

  1. Durability: The combination of copper and nickel in C71500 results in plates that are exceptionally durable, with a long service life even in harsh environments.
  2. Cost-Effectiveness: Although copper-nickel alloys like C71500 can be more expensive upfront than other materials, their longevity and low maintenance costs make them a cost-effective solution over time.
  3. Versatility: These plates can be used in a wide range of applications, from marine engineering to chemical processing, due to their excellent mechanical and chemical properties.
  4. Environmental Resistance: The superior resistance to corrosion and biofouling makes these plates ideal for use in environments that are highly corrosive or subject to biofouling, such as seawater or brackish water.
  5. High-Temperature Performance: C71500 plates maintain their strength and corrosion resistance even at elevated temperatures, making them suitable for heat exchangers, condensers, and other high-temperature applications.
