Bronze
is an alloy comprising of the metals copper and tin, of
which tin is in the lower concen-tration.
The wrought alloys (for warm and cold working through rolling,
stamping and drawing processes) contain up to 8.5 % tin,
whereas casting alloys contain up to 22 % tin. The melt
temperature depends on the various alloyed elements, but
mainly lies just under 1000 degrees Celsius.
Bronze is appreciably harder and easier to melt than copper.
Moreover bronze shows good wear properties and has very
good salt water and corrosion resistance. Although the conductivity
reduces as the tin concentration increases, the strength
and hardness increase. Generally bronze offers good spring
and frictiion properties, and has very good fatigue and
is unaffected by stress corrosion.
Bronze is a material from antiquity, yet at the same time
one of the modern era - truly a material evolving with the
times.
The first bronze was produced around 3000 years BC. In those
days it was used to produce jewellery, weapons and tools.
In the Middle Ages it was bells and cannons. Today in the
age of bits and bytes, bronze has taken an outstanding position
amongst raw materials. This is especially to be found where
electronic components and computer-controlled equipment
are required. In fact bronce plays a central roll in the
areas of data and informatiion transfer, measurement and
instrumentation technology, the automotive industry, entertainment
and domestic goods.
