Admiralty brass is a type of brass alloy that contains copper, zinc, and small amounts of tin and arsenic. Its spelling is phonetically written as /ˈæd.mə.rəl.ti bræs/. The initial syllable "ad" is pronounced with a short vowel sound and the stress is on the third syllable "ral". The "t" in "admiralty" is pronounced as a silent consonant, while the "ti" at the end is pronounced as /ʃ/ as in "nation". Admiralty brass is known for its corrosion resistance and is commonly used in marine applications.
Admiralty brass is a type of alloy that is composed primarily of copper (around 70-76%) and zinc (around 23-29%). It is a widely used type of brass due to its exceptional corrosion resistance and excellent formability. The name "admiralty" is derived from its initial use in maritime applications, particularly in the construction of naval ships.
The high copper content in admiralty brass provides excellent resistance to seawater corrosion, making it an ideal choice for marine environments. It is known for its durability, strength, and resistance to biofouling and dezincification. This type of brass also exhibits good heat transfer properties, which further increases its usefulness in equipment such as heat exchangers and condensers.
Admiralty brass is well-suited for various manufacturing processes, including hot forging, cold working, and machining. It can be easily fabricated into different shapes and forms, allowing it to be used in a wide range of applications such as tubing, fittings, valves, and components for marine, industrial, and architectural purposes. Its attractive golden color also makes it popular for decorative applications.
Overall, admiralty brass is a versatile and durable alloy with excellent resistance to corrosion, making it highly desirable in marine and other harsh environments. Its numerous properties and applications have solidified its position as a reliable and widely used material in various industries.
The word "admiralty brass" originates from the term "Admiralty metal", which refers to a specific type of brass alloy. The name comes from its historical use in naval applications by the British Admiralty. Admiralty brass was initially developed in the mid-19th century to be used in the construction of various components in naval ships. It was preferred due to its corrosion resistance and ability to withstand marine environments. Over time, the name has evolved into "admiralty brass", which is now widely used to describe this specific type of brass alloy.
