· Cu12Ni63Sn25

Cu12Ni63Sn25 is a copper-nickel-tin ternary alloy belonging to the cupronickel family, commonly known as nickel silver or german silver when tin is a primary alloying addition. This alloy combines the corrosion resistance of cupronickel with enhanced hardness and wear resistance from tin additions, making it suitable for demanding marine and industrial environments where both strength and durability are critical.
