What Aluminum Alloys Are Used in Marine Applications

Wrought Copper Nickel alloy , similar to C71500 with a more tightly controlled chemistry to limit all residuals as potential contaminants.  It has Good corrosion resistance to Salt water but will corrode quickly when Ammonia or Sulfides are present.


Some common applications for Copper Nickel include electronics and microwave condensers as well as Vacuum Electron Devices. It is also suitable for Brazing operations.


C71580 copper nickel provides a unique blend of durability and conductive properties, making it an ideal choice for various industry applications. For instance, the shipbuilding industry often chooses this alloy due to its excellent corrosion resistance to saltwater, reducing the risk of degradation over time and extending the vessel’s life span.


The electronics industry also favors copper nickel for its superior electrical conductivity. This property plays a crucial role in the effective functioning of electronic devices. For instance, in microelectronics, where you use miniature components, copper-nickel alloy allows for the efficient transmission of electrical signals without significant energy loss. This step translates to more reliable devices and improved energy efficiency, a critical aspect in an era dominated by the need for sustainable solutions.


The material’s suitability for brazing operations further expands its applications. Brazing, a metal-joining process whereby a filler metal is heated above the melting point and distributed between two or more close-fitting parts by capillary action, demands materials that can withstand high temperatures without compromising their structural integrity. C71580 copper nickel’s ability to maintain its properties under such conditions makes it a popular choice for these operations.


Despite its impressive properties, it’s worth noting that the round copper nickel bar can rust quickly when exposed to ammonia or sulfides. This attribute requires careful consideration during the material selection, particularly in environments where these substances might be present.


With its robust characteristics, such as impressive corrosion resistance to saltwater, excellent electrical conductivity, and suitability for brazing operations, C71580 copper nickel is a versatile and trusted material across different industries.


Ultimately, proper handling and usage of this alloy can increase product longevity and enhance application performance. So if you’re looking for a reliable and durable material that offers excellent conductivity and corrosion resistance, look no further than C71580 copper nickel from Wieland Diversified. This alloy covers you for electronics, shipbuilding, or any other industry.
