Copper – the metal of the century

Copper was used as much as 10,000 years ago, during the Stone Age. Even the Colossus of Rhodes was once built of copper. Thousands of years later, copper was also used for refinement, where it is still valued due to its corrosion protection properties. It is also one of the best electrical conductors and a very good heat conductor.

Brass – for highest demands

Brass is a sophisticated mix of copper and zinc – also visually – used often and gladly even by artisans due to its gold-like colour. Already used by the Assyrians and Babylonians, the galvanic alloy is now also used in areas where conductivity and stability are of essence.

Steel – a long history

Wieland the Smith supposedly fed his chicken iron chips to surpass his old blade's quality with a sword made of chicken excrement. It is known today that the nitrogen produced in this manner may, in fact, increase quality considerably. There are more than 2,500 standardised steel types in the world. They are processed into serial goods of many kinds.

Aluminium – material with a future

Aluminium is relatively young, as metals go. It has not been used for very long yet. It was discovered by Sir Humphrey Davy in 1808. Aluminium has already secured its place in industry and economy, often used in the packaging, aviation and aerospace, as well as automotive industries – mainly because of its light weight.
