Historical records show that the use of copper alloys like brass started in Asia at around 5th century BC. Since then, alloys have evolved to become stronger, more durable, and at the same time, more versatile in terms of application. One such alloy that is known for its quality is Naval brass, denoted by international standards as C464.
Naval brass contains 59% copper, 40% zinc, and 1% tin. The alloy is well-recognized for its high corrosion resistance and its compatibility for use in marine environments. For this reason, boat parts and other components like nuts, bolts, rivets, and propeller shafts are built from naval brass.
This type of brass is ideal for welding and soldering.
Naval brass also adapts well to pressing and hot forging. The high zinc content of Alloy C464 makes it ideal for casting, as it hardens to become a very strong piece. As naval brass ages, its color changes from a shade of gold to a deep chocolate brown.
Limitations of Naval Brass
However, even though naval brass is known to be rigid and tough, it should be kept away from solutions containing ammonia or amines while being exposed to the air, as these conditions may lead to stress corrosion cracking.
