What is C71500 Copper Nickel?

Copper-nickel alloys are one of the few alloy systems with naturally occurring antifouling qualities and are renowned for their outstanding resistance to sea water corrosion. Their mechanical characteristics make it possible to manufacture them in all product shapes and easily create even the most complex designs. They have offered dependable service for decades and practical answers to the technological problems of the present.

Copper is strengthened and more resistant to corrosion when nickel is added, and the alloy is still ductile. To improve copper-strength, nickel’s corrosion resistance, hardness, weldability, and cast ability, other elements can be added.

Properties and Applications of Copper Nickel

Nickel and copper complement each other nicely because they are adjacent elements on the periodic chart. Due to their comparable qualities, these substances are frequently combined to form alloys. These kinds of alloys, which come in a variety of forms, like QQ N 281, are incredibly strong and appropriate for a wide range of sectors. Use this manual to learn about some of the fundamental  Properties C71500 Copper Nickel


Antimicrobial: These alloys naturally kill microorganisms when kept in good condition. In fact, the U.S. Environmental Protection Agency has 400 copper alloys on its list of materials that may eradicate six types of bacteria.

Corrosion Resistant: These alloys are frequently employed in nautical and marine applications because they do not readily rust. C71500 copper nickel metals can withstand salty settings for a long time since seawater does not readily harm them.

Similar to its capacity to endure in seawater without corroding, copper-nickel alloys are also impervious to the development of mollusks, anemones, algae, and sea moss. Marine metals without this characteristic are easily engulfed by marine life.


Energy: Because of their durability and corrosion resistance, copper-nickel alloys are frequently employed in offshore oil and gas drilling. Additionally, they are utilised in equipment like oil coolers throughout the actual refining process. For instance, 63% nickel is permitted in nickel 405, along with copper, iron, and other components. This substance is utilised in nuclear vessels, sulfuric acid plants, and oil pipes.

Ships and Piping: Nickel-copper alloys are most frequently employed in maritime applications because to their outstanding corrosion resistance. Pumps, exchanger tubes, and boat hulls all fall under this category. They are also employed to build water and oil pipelines under the sea.

Coins: These alloys have other non-marine uses, such as coin minting. Copper-nickel alloys are used to create the one and two Euro as well as the five-cent nickel in the United States. These currencies have antibacterial qualities as well because they are composed of this alloy. By causing alteration, this lessens the transmission of disease.
