Brass:
Brass is an alloy of copper and zinc. There are a number of
Brass alloys, each with its own properties and applications. Here is a short
list of the types craftspeople are likely to encounter:
Gilding metal: Cu 95%, Zn 5% Golden in colour, used
for items that are to be gold plated.
Pinchbeck metal: Cu 88%, Zn 12% Used as a gold
substitute by Victorian jewellers.
Red brass: Cu 85%, Zn 15% Used for costume jewellery
Yellow brass: Cu 65%, Zn 35%, Melting point: 1660 deg
F / 904.4 deg C, Used for wire drawing, beads, chains, rivets, stamping and
spinning
Muntz brass: Cu 60%, Zn 40%, Melting point: 1650 deg
F / 898 deg C, can be hot forged, used in applications where corrosion
resistance is important.
Leaded brasses: These contain 0.5 to 3% lead which
makes them easily machine-able.
Bronze:
Bronzes are basically Copper - Tin alloys, but Cu - Si alloys
are also considered a bronze. Some bronze alloys are suited to machining, while
others have been developed specifically for casting.
