admiralty brass
Học thuậtThân thiện
Definition
Noun: 1. A type of alpha-beta brass alloy containing tin: Admiralty brass is a specific copper-zinc alloy to which a small percentage of tin has been added. This tin content significantly increases its resistance to corrosion, particularly in marine environments. 2. A seawater-resistant brass alloy: Its primary defining characteristic is its enhanced durability and resistance to dezincification and corrosion when exposed to saltwater, making it suitable for maritime applications.
Usage Examples
- Noun:
- The ship's condenser tubes were made from admiralty brass for its excellent seawater resistance.
- When selecting a material for the new heat exchanger, the engineers specified admiralty brass.
Advanced Usage
- The term "Admiralty Metal" is a registered trademark for a specific formulation of this alloy. In technical and commercial contexts, "Admiralty brass" and the trademarked "Admiralty Metal" are often used interchangeably to refer to tin-containing, seawater-resistant brass alloys, though precise compositions may vary by manufacturer.
Variants and Related Words
- Admiralty Metal (trademark): A proprietary name for a type of admiralty brass.
- Naval brass: A related alloy with a slightly different composition (often containing additional elements like lead or arsenic for machinability or further corrosion resistance), also used in marine environments.
- Alpha-beta brass: The broader category of brass alloys to which admiralty brass belongs, characterized by a two-phase microstructure.
Synonyms
- Tin brass: A descriptive synonym highlighting the key alloying element.
- Marine brass: A functional synonym emphasizing its primary use case.
Related Phrases/Technical Terms
- Dezincification resistance: A key property of admiralty brass; it describes the alloy's ability to resist the selective leaching of zinc from its surface, a common form of corrosion in standard brasses exposed to seawater.
- Condenser tube alloy: A common application-specific term, as admiralty brass is historically and frequently used for tubes in marine condensers and heat exchangers.
