Product Overview Nickel-Silver Alloys, also known as copper-nickel-zinc alloys, are celebrated for their silver-like appearance, strength, and corrosion resistance. These alloys—including C75200, C7521, C75700, C77000, and C7701—do not contain silver but are named for their resemblance to it. Widely used in decorative applications, electrical components, and industrial parts, these alloys provide both aesthetic appeal and functional durability, making them suitable for various industries. Available Grades C75200 – Offers excellent corrosion resistance and good workability, often used in decorative and musical applications. C7521 – Provides improved machinability while maintaining strength and corrosion resistance, ideal for precision components. C75700 – Known for enhanced strength and wear resistance, suitable for industrial and mechanical applications. C77000 – Known for its aesthetic finish and corrosion resistance, used in electrical connectors and decorative parts. C7701 – Similar to C77000, with improved machinability and strength, suitable for detailed, high-precision applications. Key Properties Corrosion Resistance: Performs well in various environments, including marine and industrial. Aesthetic Appeal: Silver-like appearance, ideal for decorative applications.
