BRASS |
COPPPER/BRONZ |
CHARACTERS |
Brass is an alloy of copper and zinc. |
Bronze is a metal alloy consisting primarily of copper, usually with tin as the main additive, but sometimes with other elements such as phosphorus, manganese, aluminum, or silicon. |
PROPERTIES |
Higher malleability than zinc or copper. Low melting point (900 Celsius); flows when melted. Combinations of iron, aluminum, silicon & manganese make brass corrosion resistant. Susceptible to stress cracking when exposed to ammonia. Not as hard as steel. |
Hard and brittle. Melts at 950 centigrade but depends on amount of tin present. Bronze resists corrosion (especially seawater corrosion) and metal fatigue more than steel and is also a better conductor of heat and electricity than most steels. |
UESE |
Decorative; Low-friction applications (locks, gears, doorknobs, ammunition, valves); Plumbing/electronics; Musical instruments for acoustic properties; Zippers & uses where it's important to negate spark (fittings & tools around explosive gas). |
Used in boat and ship fittings, propellers and submerged bearings because of resistance to salt water corrosion. Widely used for cast bronze sculpture; Bearings, clips, electrical connectors and springs; For top-quality bells and cymbals. |
COLOR |
Muted yellow, somewhat similar to gold, but duller. |
Reddish brown. |
HISTORY |
Brass was first known to exist in about 500 BC. |
Bronze dates to about 3500 BC. |
