Copper Nickel

C61300 Aluminum Bronze

Strength and Performance in Extreme Environments

C61300 Aluminum Bronze is a copper alloy that includes zinc, iron, and aluminum, offering exceptional properties for marine applications. This alloy provides corrosion resistance and high-velocity seawater erosion resistance comparable to C71500 70/30 Copper Nickel, but it boasts greater strength and superior fatigue resistance. Primarily available in wrought plate form, C61300 is commonly utilized in seawater service, steam condensers, oil coolers, and various heat exchangers. Tubesheets crafted from C61300 Aluminum Bronze are frequently paired with copper-nickel tubes in seawater-cooled condensers and heat exchangers, enhancing overall performance and durability. The unique combination of strength, corrosion resistance, and thermal conductivity makes C61300 an ideal choice for demanding environments, ensuring reliable operation in challenging conditions. This versatility positions Aluminum Bronze 61300 as a favored material for engineers and manufacturers seeking robust solutions for their heat exchange systems.
