Brass and Hygiene
Copper and brass are playing a leading role in the fight against
hospital-acquired infections such as MRSA and Clostridium
difficile. It has been shown that these pathogens, which can be
spread by touch, will die in a few hours on copper/brass surfaces.
This does not happen on stainless steel or plastic.
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.
Brass also has excellent thermal conductivity, making it a first
choice for heat exchangers (radiators). Its electrical conductivity
ranges from 23 to 44% that of pure copper.
|Alloy name||Copper (%)||Zinc (%)||Tin (%)||Lead (%)||Other||Notes|
|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.|
Brass in Africa
Some of the most famous objects in African art are the lost wax
castings of West Africa, mostly from what is now Nigeria, produced
first by the Kingdom of Ife and then the Benin Empire. Though
normally described as "bronzes", the Benin Bronze plaques, now
mostly in the British Museum and other Western collections, and the
large portrait heads such as the Ife Head of "heavily leaded
zinc-brass" and the Bronze Head of Queen Idia, both also British
Museum, are better described as brass, though of variable
compositions. Work in brass or bronze continued to be important in
Benin art and other West African traditions such as Akan
goldweights, where the metal was regarded as a more valuable
material than in Europe.
