The mouthpieces of both brass instruments and, less commonly, woodwind instruments are often made of brass among other metals as well. Next to the brass instruments, the most notable use of brass in music is in various percussion instruments, most notably cymbals, gongs, and orchestral (tubular) bells (large "church" bells are normally made of ...
Gun metal, also known as red brass in the United States, is a type of bronze – an alloy of copper, tin, and zinc. Proportions vary but 88% copper, 8–10% tin, and 2–4% zinc is an approximation. Originally used chiefly for making guns, it has largely been replaced by steel for that purpose.
A later substitute of a mixture of metals resembling ormolu was developed in France and called pomponne, though the mix of copper and zinc, sometimes with an addition of tin, is technically a type of brass. From the 19th century the term has been popularized to refer to gilt metal or imitation gold. [2]
Forms of brass, an alloy of copper and zinc made by concurrently smelting the ores of these metals, originate from this period (although pure zinc was not isolated until the 13th century). The malleability of the solid metals led to the first attempts to craft metal ornaments, tools, and weapons.
Made in an English school metalwork class, 1970s–1980s Gilding metal is a form of brass (an alloy of copper and zinc ) with a much higher copper content than zinc content. Exact figures range from 95% copper and 5% zinc [ 1 ] to “8 parts copper to 1 of zinc” (11% zinc) in British Army Dress Regulations.
Brass was made using a cementation process but this was replaced by speltering, the direct alloying of copper and zinc metal which was ... The dictionary definition ...

Art in bronze and brass dates from remote antiquity. These important metals are alloys, bronze composed of copper and tin and brass of copper and zinc. Proportions of each alloy vary slightly. Bronze may be normally considered as nine parts of copper to one of tin. Other ingredients which are occasionally found are more or less accidental.
