Overview
C97300, also known as nickel silver or leaded nickel brass, is a unique copper-nickel-zinc alloy distinguished by its silvery-grey appearance, unlike the typical golden hue associated with bronze. Despite its name, it contains no actual silver. The addition of nickel not only contributes to its distinctive color but also enhances its corrosion resistance, making it suitable for applications in various environments. While C97300 offers excellent corrosion resistance and good machinability due to the presence of lead, it is important to note that it possesses lower tensile strength and a lower melting point compared to other bronze alloys. This alloy does not respond to heat treatment, so its properties are primarily determined by its composition and manufacturing process.
Typical Uses
Steam applications in turbines and pumps, packing rings, seal rings, labyrinth rings, and valve components and fittings.
