C64200 C642 Silicon Aluminum Bronze (AMS 4634)

Naval Brass C46400 is nominally composed of 60% copper, 39.2% zinc, and 0.8% tin. As is typical of brass alloys with the duplex alpha + beta structure, C46400 has good strength and rigidity. By substituting tin for an equal quantity of zinc, a high corrosion resistance to seawater is achieved.

C19140 Low Leaded Nickel Copper is a corrosion-resistant copper-nickel alloy with a reduced lead content, known for its good thermal and electrical conductivity, enhanced resistance to dezincification, and improved formability, used in condenser tubes, heat exchangers, and components requiring resistance to corrosive environments.

C61800 Aluminum Bronze is a premium copper alloy known for its exceptional corrosion resistance and strength, particularly in marine and chemical processing environments. With a high aluminum content, this alloy exhibits excellent resistance to erosion, cavitation, and pitting, making it ideal for use in seawater pumps, valves, propellers, and other marine components. Additionally, C61800's strong mechanical properties and good thermal conductivity make it suitable for electrical and heat exchange applications.

CuNi30Fe1Mn Copper Nickel offers excellent corrosion resistance, especially in marine salt water environments. The main, wrought copper-nickel alloys chosen for sea water service contain 10 or 30 percent nickel.
