ASTM B122/B122M C71500 Plates | Copper Nickel 70/30 Plates Supplier & Exporter
ASTM B122/B122M C71500 Plates are high-performance copper-nickel (70/30) alloy plates known for excellent corrosion resistance, especially in seawater environments. Manufactured under the B122/B122M Standard Specification, these plates offer superior strength, durability, and resistance to biofouling, making them ideal for marine, offshore, desalination, and heat exchanger applications. The C71500 Copper Nickel (70/30) alloy contains 70% copper and 30% nickel, providing enhanced resistance to stress corrosion cracking and erosion in harsh environments.
What is ASTM B122/B122M C71500 Plate?
ASTM B122/B122M C71500 Plates refer to copper-nickel alloy plates manufactured as per the ASTM B 122/B122m standard. This specification covers rolled copper alloy plates, sheets, and strips such as:
- b122 sheet
- b122 strips
- ASTM B122 Plate
- ASME B 122 C71500 Sheet
The b 122 c71500 grade belongs to the C71500 Alloy, widely known as Copper Nickel C715 – C71500 or C71500 Copper Nickel (70/30). It is engineered for superior corrosion resistance in aggressive environments like seawater and industrial fluids.
