Brass
Brass is a metal alloy made of copper and zinc; the proportions of
zinc and copper can be varied to create a range of brasses with
varying properties. It is a substitutional alloy: atoms of the two
constituents may replace each other within the same crystal
structure.
By comparison, bronze is principally an alloy of copper and tin.
However, bronze and brass may also include small proportions of a
range of other elements including arsenic, phosphorus, aluminium,
manganese, and silicon. The term is also applied to a variety of
brasses, and the distinction is largely historical. Modern practice
in museums and archaeology increasingly avoids both terms for
historical objects in favour of the all-embracing "copper alloy".
Colours of Brass
Brasses have a range of attractive colours,red, yellow, gold,
brown, bronze, silver. Brass with 1% manganese will weather to a
chocolate brown colour. Nickel silvers will polish to a brilliant
silver colour. Brasses are easy to shape and, with all these
colours available, it is not surprising that architects and
designers have used brasses to enhance the appearance of new and
refurbished buildings, both inside and out.

Properties
Brass has higher malleability than bronze or zinc. The relatively
low melting point of brass (900 to 940 °C, 1,650 to 1,720 °F,
depending on composition) and its flow characteristics make it a
relatively easy material to cast. By varying the proportions of
copper and zinc, the properties of the brass can be changed,
allowing hard and soft brasses. The density of brass is 8.4 to 8.73
grams per cubic centimetre (0.303 to 0.315 lb/cu in).
Corrosion-resistant brass for harsh environments
The so-called dezincification resistant (DZR or DR) brasses,
sometimes referred to as CR (corrosion resistant) brasses, are used
where there is a large corrosion risk and where normal brasses do
not meet the standards. Applications with high water temperatures,
chlorides present, or deviating water qualities (soft water) play a
role. DZR-brass is excellent in water boiler systems. This brass
alloy must be produced with great care, with special attention
placed on a balanced composition and proper production temperatures
and parameters to avoid long-term failures.
