BRASS ALLOYS
Alloy name | Copper (%) | Zinc (%) | Tin (%) | Lead (%) | Other | Notes |
Abyssinian gold | 90 | 10 | ||||
Admiralty brass | 69 | 30 | 1 | Tin inhibits loss of zinc in many environments. | ||
Aich's alloy | 60.66 | 36.58 | 1.02 | 1.74 iron | Designed for use in marine service owing to its corrosion resistance, hardness and toughness. A characteristic application is to the protection of ships' bottoms, but more modern methods of cathodic protection have rendered its use less common. Its appearance resembles that of gold. | |
Aluminum brass | 77.5 | 20.5 | 2% aluminum | Aluminum improves corrosion resistance. It is used for heat exchanger and condenser tubes. | ||
Arsenical brass | arsenic, frequently aluminum | Used for boiler fireboxes. | ||||
Cartridge brass (C260) | 70 | 30 | — | ≤ 0.07 | Good cold working properties. Used for ammunition cases, plumbing, and hardware. | |
Common brass | 63 | 37 | Also called rivet brass. Cheap and standard for cold working. |

aquaculture
The bactericidal properties of brass have been observed for
centuries, particularly in marine environments where it prevents
biofouling. Depending upon the type and concentration of pathogens
and the medium they are in, brass kills these microorganisms within
a few minutes to hours of contact.
A large number of independent studies confirm this antimicrobial
effect, even against antibiotic-resistant bacteria such as MRSA and
VRSA. The mechanisms of antimicrobial action by copper and its
alloys, including brass, are a subject of intense and ongoing
investigation.
Research is being conducted at this time[when?] to determine
whether brass, copper, and other copper alloys can help to reduce
cross contamination in public facilities and reduce the incidence
of nosocomial infections (hospital-acquired infections) in
healthcare facilities.
Season cracking
Brass is susceptible to stress corrosion cracking, especially from
ammonia or substances containing or releasing ammonia. The problem
is sometimes known as season cracking after it was first discovered
in brass cartridges used for rifle ammunition during the 1920s in
the British Indian Army. The problem was caused by high residual
stresses from cold forming of the cases during manufacture,
together with chemical attack from traces of ammonia in the
atmosphere. The cartridges were stored in stables and the ammonia
concentration rose during the hot summer months, thus initiating
brittle cracks. The problem was resolved by annealing the cases,
and storing the cartridges elsewhere.
