   Islamic Golden Age brass astrolabe Brass lectern with an eagle. Attributed to Aert van Tricht, Limburg (Netherlands), c. 1500.. Brass is an alloy of copper and zinc, in proportions which can be varied to achieve different colours and mechanical, electrical, acoustic and chemical properties, [1] but copper typically has the larger proportion, generally 66% copper and 34% zinc.

3. Repoussé and chasing - Wikipedia

   en.wikipedia.org/wiki/Repoussé_and_chasing

   Repoussé (French: ⓘ) or repoussage (ⓘ) is a metalworking technique in which a malleable metal is shaped by hammering from the reverse side to create a design in low relief. Chasing (French: ciselure ) or embossing is a similar technique in which the piece is hammered on the front side, sinking the metal.

4. Dutch metal - Wikipedia

   en.wikipedia.org/wiki/Dutch_metal

   Dutch metal is a form of brass. The alloy typically consists of 85–88% copper and the remainder being zinc. It is also known by other names such as "composition gold leaf", "Dutch gold", "Schlagmetal" and "Schlag leaf". [1] It is very malleable and ductile and so can be beaten into very thin sheets.

5. Jewelry wire - Wikipedia

   en.wikipedia.org/wiki/Jewelry_wire

   Jewelry wire is wire, usually copper, brass, nickel, aluminium, silver, or gold, used in jewelry making. Wire is defined today as a single, usually cylindrical, elongated strand of drawn metal. However, when wire was first invented over 2,000 years BC, it was made from gold nuggets pounded into flat sheets, which were then cut into strips. The ...

6. Gilding metal - Wikipedia

   en.wikipedia.org/wiki/Gilding_metal

   Gilding metal is used for various purposes, including the jackets of bullets, driving bands on some artillery shells, [3] as well as enameled badges and other jewellery. The sheet is widely used for craft metalworking by hammer working. [1] It is also used particularly as a lower-cost training material for silversmiths.

7. Cladding (metalworking) - Wikipedia

   en.wikipedia.org/wiki/Cladding_(metalworking)

   No heat-affected zone is produced in the bond between metals. The explosion propagates across the sheet, which tends to expel impurities and oxides from between the sheets. Pieces up to 4 x 16 metres can be manufactured. The process is useful for cladding metal sheets with a corrosion-resistant layer. [2]
