Both copper and nickel are metals that could be easily alloyed. Both pure materials are alloyed with each other to form copper-nickels or what is otherwise known as Cuppro Nickel Round Head Bolts. Since the alloy primarily consists of both these metals, the properties inhered by the alloy is reminiscent of each metal. For instance, the copper nickel 90/10 Fasteners exhibits superior resistance to stress corrosion.

Therefore, it is not uncommon to see marine engineers use Cupro Nickel (Cu-Ni) 90/10 Fasteners across several applications including desalination plants, heat exchangers or to fasten marine components. The most significant use of Cu-Ni UNS C70600 90/10 Spring Washers is its application in high-velocity seawater. High velocity seawater, which already has a high level of salt, causes a lot of stress to the components being used. The velocity of the current is so rapid, that it could cause conventional steel alloys to fail. Hence, using a copper rich alloy like Cu-Ni 90/10 Head Hex Bolts to fasten the boats is a good idea. The material is strong, as it is resistant to various bio life found in marine environments.

And since the metal is inherently antimicrobial, using the ASTM B151/B152 UNS C71500 70/30 Screws makes for a superior alternative for touch surface applications. Properties exhibited by the Cupro Nickel (Cu-Ni) 70/30 Fasteners include high strength, good workability, and good formability. Some applications call for welding or soldering.  Since the Copper Nickel Fasteners exhibits good weldability, many manufacturers recommend using them as fasteners in applications that need weldability.
