Naval brass and brass are both alloys with copper as the main metal component, but there are obvious differences between the two. This paper introduces the characteristics of two copper alloys, naval brass and common brass, including their compositions, mechanical properties and application areas. Through comparative analysis, we can better understand the differences and similarities between these two copper alloys, as well as their application value in different fields.

Introduction to the two types of copper:

Naval Brass: is a type of brass specifically designed for use in the marine environment. It consists of approximately 60 per cent copper, 39 per cent zinc and a small amount of tin. The addition of tin to the alloy enhances corrosion resistance, making naval brass particularly suitable for use in seawater and other harsh marine conditions.

By contrast, brass is a generic term for a variety of copper-zinc alloys with different compositions and properties.

The difference between naval brass and brass:

Corrosion resistance: the corrosion resistance of ordinary brass is poorer than that of naval brass.

  • Naval brass has a higher zinc content, making it more resistant to the corrosive effects of salt water than ordinary brass. In the marine environment, it can resist the erosion of seawater, salt spray and other corrosive media and maintain long-term stable performance. This makes it ideal for marine equipment components and fittings, such as propellers, shafts and valves, where seawater corrosion is a major problem.
  • Ordinary brass has relatively poor corrosion resistance and is susceptible to erosion by air, water, and chemical media. As a result, it may not be as Ordinary brass has relatively poor corrosion resistance and is susceptible to erosion by air, water, and chemical media. As a result, it may not be as stable as navy brass in some corrosive environments.

Another important difference between naval brass and brass is their mechanical properties.

  • Naval brass is known for its excellent strength, toughness, and resistance to fatigue and stress corrosion cracking. These properties are critical for marine applications where parts are subjected to high levels of mechanical stress and cyclic loading.
  • Brass, while still offering good strength and machinability, may not have the same level of mechanical properties as naval brass, depending on its specific composition, but has good ductility and toughness. It is suitable for applications where strength is not required, such as the manufacture of valves and pipes.

In summary, although both naval brass and brass are copper-based alloys, they have different compositions and properties for different applications. Naval brass is designed to withstand harsh marine environments and has superior corrosion resistance and mechanical properties compared to brass. It is usually suitable for shipbuilding, marine engineering, petrochemicals and other fields. While ordinary brass is suitable for construction, automobile manufacturing, electronics and other fields. Therefore, the choice should be made according to the specific needs in the actual application.
