UN SC95800 is a high-strength nickel aluminum bronze alloy which is one of the leading in terms of corrosion-resistance and mechanical strength. It is a mixture of copper, nickel, aluminum, and iron that has elevated properties of strength and durability. This makes it particularly suitable for marine and industrial applications where the corrosion resistance is crucially necessary. It comprises usually 78% of the chemical composition of copper, 10% nickel, 5% aluminium, and 5% iron that makes it exceptional with respect corrosion in seawater, erosion and cavitation. Specifications and ratings related to UNS C95800 are uniform under ASTM and SAE ratio standards. In-depth tables, charts and a PDF document are just a few clicks away, offering a wealth of information about its physical qualities, mechanical features, and suggested applications for designers, metallurgists, engineers and producers.
UNS C95800 is a high performance, corrosion-resistant nickel alloy bronze with good mechanical characteristics and therefore is a suitable material for different uses. The chemical composition of this type of metal is often 83-88% of copper, about 4-5% of aluminum, 4-5% of nickel and 1-2% of iron plus some other elements. This grade is the most superior one to seawater corrosion. Thus, it is the best for marine environments and, for example, underwater components like propellers, valves and fittings. Moreover, it has the strength and wear resistance that makes it suitable for use in high load applications like gears and bushings. Our product meets ASTM B148/B148M and AMS 4880 standards, thus guaranteeing the quality and performance.

Ease of Fabrication: UNS C95800 Copper is quite easy to produce through techniques like machining, welding, and brazing which makes it possible to manufacture the complex components quickly and efficiently.
Disadvantages:
Cost: Copper, such as UNS C95800, can be quite costly compared to other materials, hence the overall cost of projects or products where it is used can be affected.
Susceptibility to Corrosion in Certain Environments: Although copper usually has good corrosion resistance, it can corrode in some situations like contact with certain chemicals or high humidity environments.
Potential for Galling: Copper alloys like UNS C95800 may show galling or seizing in sliding or rubbing applications, which, in turn, can affect their performance and longevity.
Limited Strength at Elevated Temperatures: The mechanical properties of copper, such as the strength, may be greatly reduced at high temperatures, making it unsuitable for high-temperature applications.
Low Hardness: Copper is generally softer than other engineering materials, thus it may cause wear and deformation in applications that are exposed to high loads or abrasive conditions.
