Naval brass, as its name suggests, was developed for use in marine applications. It is a copper alloy with a composition that looks something like this: 59% copper, 40% zinc, and 1% tin. Together, these three metals create a highly durable and corrosion-resistant material, making it the perfect option for fresh and saltwater applications.
This article explores what naval brass is and what it is used for.
Why The Composition of Naval Brass Matters
The composition of an alloy always gives it a unique set of properties that make it the most successful choice for certain applications. The makeup can impact all sorts of things, including its strength, durability, and malleability.
For instance, brass is a metal alloy made up of copper and zinc. Naval brass, on the other hand, is a combination of copper and zinc — with the addition of a little tin. It is this small additional material that transforms the composition and makes naval brass great for use in the water.
So, why is the composition of naval brass so important?
With the addition of tin, the metal alloy becomes known as naval brass. Unlike other types, it becomes corrosion resistant — a trait that is vital for a metal to work successfully when exposed to wet conditions, including harsh saltwater. The tin also reduces the risk of dezincification, extending the life of the alloy.
Another important element of this composition is zinc. Having at least 35% zinc within the alloy increases its strength. This plays a role in the machinability of the metal. It is important to note that too much zinc can make the brass more tough to work with and less ideal for various applications.
Common Naval Brass Applications
With such properties, it is no wonder why naval brass is so popular in so many ways. You can commonly find it in industrial settings as fasteners, fittings, bushings, screws, pins, and bolts. It does well in hot, cold, and wet conditions due to its high tensile strength and ability to handle high temperatures and high pressure.
Further, it’s no surprise that you will find naval brass used in the manufacturing and building of ships, including those above and below the water. After all, this alloy can be used in producing submarines that can withstand the pressures in deep ocean depths.
A few additional applications where you may find naval brass include:
Propeller shafts
Welding rods
Valve stems
Aircraft turnbuckle barrels
Condenser plates
Cartridge cases for ammunition
Occasionally, naval brass is incorporated into architectural and decorative applications. This includes things like doors, elevators, commercial entryways, and storefronts.
When used in appropriate applications, you can feel confident of its longevity.
Is Naval Brass Right For Your Application?
Naval brass is so important in so many ways, benefitting a large number of different industries. It can be sold in a variety of shapes and sizes, including sheets, tubes, and the most popular option, solid bars that are cut to length.
