Cupro Nickel 70/30 Fasteners Supplier

Cupro Nickel 70/30 Fasteners are highly sought-after for engineering fastening applications due to their exceptional features and benefits. Cupro Nickel 70/30 Fasteners are a type of copper-nickel alloy consisting of 70% copper and 30% nickel, with small amounts of iron and manganese. This combination provides high resistance to corrosion, erosion, and biofouling, making them ideal for marine applications.

In addition to their superior resistance to seawater, these fasteners have good elasticity, high strength, and excellent fabricability. They can be easily formed, machined, and welded, making them suitable for various industrial and commercial uses. Cupro Nickel 70/30 Fasteners are available in various shapes and sizes, including bolts, nuts, screws, washers, and studs. They can also be customized to meet specific requirements, such as thread type, length, and surface finish.
