Key Features:
The C71500 Copper-Nickel alloy, also known as Cupronickel 70/30 (Cu70Ni30), is a high-strength, corrosion-resistant alloy composed primarily of copper (Cu) and nickel (Ni). The alloy typically consists of 70% copper and 30% nickel, with small additions of iron and manganese to enhance its mechanical properties and corrosion resistance, especially in marine and seawater environments.
