Alpha Nickel

Cupro Nickel Fasteners Manufacturer, Supplier In Mumbai India

Alpha Overseas is well known in the industry for producing and distributing Copper Nickel fasteners. Cupro Nickel Fasteners are created from an alloy of copper, nickel, and other reinforcing elements like iron and manganese. The external male thread of copper-nickel bolts, a threaded fastener, must match a pre-formed female thread, such as a nut. It typically has a copper content of 60 to 90 percent. Nickel content in items and components used in seawater is frequently between 10% and 30%. An externally threaded fastener called a copper-nickel screw can be placed into holes in assembled pieces. Materials are fastened by engaging the screw thread with a corresponding female thread in the matching part. Metals like copper and nickel could be alloyed with ease. Cupro Nickel Round Head Bolts, also known as copper nickels, are created by combining the two pure materials. The features of the alloy are reminiscent of each metal because it is predominantly composed of each of these metals. An excellent example is the greater resistance to stress corrosion displayed by copper nickel 90/10 Fasteners.

As a result, it is typical to see maritime engineers employ Cupro Nickel (Cu-Ni) 90/10 Fasteners for various purposes, such as to fasten marine components or in desalination plants or heat exchangers. Cu-Ni UNS C70600 90/10 Spring Washers are most frequently used in high-velocity salt water. The components under stress are subjected to high-velocity salt water, which is already quite salty. Standard steel alloys may fail because of the current's extremely high velocity. To secure the boats, it is, therefore, a good idea to use a copper-rich alloy like Cu-Ni 90/10 Head Hex Bolts. Due to its resistance to the different types of aquatic life, the material is robust.

Moreover, using UNS C71500 70/30 Screws by ASTM B151/B152 is a superior option for touch surface applications because metal is naturally antibacterial. The characteristics of Cupro Nickel (Cu-Ni) 70/30 Fasteners are high strength, good workability, and good formability. The Copper Nickel Fasteners demonstrate good weldability. Hence many manufacturers advise utilizing them as fasteners in applications that demand weldability.
