cartridge brass

Thân thiện

A worker inspects a cartridge brass shell casing on a factory table.

Definition

Noun: 1. A specific type of brass alloy, composed primarily of copper and zinc (typically containing about 30% zinc), which is valued for its ductility and strength. It is commonly formed into items like cartridges and tubing through mechanical working (wrought).

Usage

• Cartridge brass is named for its historical and primary use in manufacturing firearm cartridge cases, as it has the ideal combination of malleability for forming and strength to contain pressure.
• It is also specified for applications requiring good cold-working properties, such as in the production of tubes, pins, and springs.

Examples

• The ammunition factory switched to a higher grade of cartridge brass to improve reliability.
• Due to its excellent ductility, cartridge brass is often drawn into tubes for plumbing applications.
• A key property of cartridge brass is its ability to be deeply formed without cracking.

Advanced Usage

• In metallurgy, cartridge brass (alloy UNS C26000) is distinguished from other brass alloys, like naval brass or red brass, by its specific zinc content and resulting mechanical properties.
• The term can be used metonymically to refer to the material quality of an object: "The vintage bullet was identified by its distinctive cartridge brass."

Variants and Related Words

• Brass (noun): The broader family of copper-zinc alloys.
• Yellow Brass (noun): A common general term for brass alloys with a zinc content of 20-36%, which includes cartridge brass.
• Cartridge (noun): A case, usually made of brass, that holds a bullet, propellant, and primer.

Synonyms

• Alloy 260 (Technical synonym)
• UNS C26000 (Standardized designation)
• Yellow Brass (General, contextual synonym)

Different Meanings

• The term "cartridge brass" has a highly specific, technical meaning in metallurgy and manufacturing. It does not have common idiomatic or figurative meanings. It refers exclusively to the material itself.
