Definition

Noun: - A type of alpha-beta brass alloy containing approximately 60% copper and 40% zinc, known for its strength and suitability for hot-working processes like extrusion and rolling. It is stronger than simple alpha brasses.

Usage

Muntz metal is specifically used in industrial and marine applications due to its combination of strength, corrosion resistance, and workability. - The ship's fittings were made from durable muntz metal. - For this casting, the engineer specified muntz metal for its hot-working properties.

Advanced Usage

• Technical Specification: In metallurgy, Muntz metal is classified as a duplex brass (alpha-beta brass), which gives it a good balance of strength and ductility, especially at elevated temperatures.
• Historical Context: The alloy is named after George Fredrick Muntz, who patented it in the 19th century for sheathing the bottoms of wooden ships.

Variants and Related Words

• Yellow Metal: A common informal name for Muntz metal and similar brasses, referring to its distinctive color.
• Alpha-Beta Brass: The technical metallurgical classification for alloys like Muntz metal that have a two-phase microstructure.
• Naval Brass: A related, but distinct, alloy that typically contains around 60% copper, 39% zinc, and 1% tin for added corrosion resistance in seawater.

Synonyms

• Alpha-beta brass (technical synonym)
• 60/40 brass (descriptive synonym based on composition)
• Yellow brass (general synonym for high-zinc brasses)

Related Phrases and Terms

• Hot-worked products: Items shaped by processes like forging or extrusion while the metal is hot, a key application for Muntz metal.
• Castings: Objects formed by pouring molten metal into a mold, another common use for this alloy.

Noun

1. a brass that has more zinc and is stronger than alpha brass; used in making castings and hot-worked products
