Brass
Brass is a golden-yellow alloy of copper and zinc that imitates gold at a fraction of the price. It is one of the most used metals in costume and handmade jewelry, and also the base for pieces that later receive a gold or other metal plating.
Properties #
- Composition: copper (around 60-70%) and zinc (30-40%); more zinc gives a paler tone.
- Color: bright golden yellow, from reddish to greenish yellow depending on the ratio.
- Melting point: roughly 900 to 940 °C.
- Hardness: harder than copper, easy to file, bend and solder.
- Reaction to air: it tarnishes and forms a brown or greenish patina.
Uses in jewelry #
- Costume and fashion jewelry.
- Wire, sheet, chain and findings for handmade jewelry.
- Base for gold, silver or rhodium plating.
- Pieces with an aged or patinated finish.
