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.
The brass industry throughout the world is well organised and
equipped to recycle products at the end of their long lives and
process scrap (swarf and offcuts). Making brass from new (virgin)
copper and zinc would be uneconomical and wasteful of raw materials
so new brass products are made from recycled scrap, illustrating
the sustainable nature of this material. In the UK brass
manufacturers use almost 100% brass scrap.
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
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".
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).
Today, almost 90% of all brass alloys are recycled. Because brass
is not ferromagnetic, it can be separated from ferrous scrap by
passing the scrap near a powerful magnet. Brass scrap is collected
and transported to the foundry where it is melted and recast into
billets. Billets are heated and extruded into the desired form and
size. The general softness of brass means that it can often be
machined without the use of cutting fluid, though there are
exceptions to this.
