Was sind die Vorteile des Metalls?

Metals are used because of their high strengths and because they can be processed to “simple” alloys. Steel can be produced from iron. Made of copper and tin, bronze. The alloys are often firmer and harder, or more wear-resistant than their starting metals. Straight steel, i.e. an alloy of iron and carbon, is the pillar of our civilization. Without steel, modern machine and tool construction would be as good as impossible. The material properties of steel are adjustable in a very wide frame. From cheap construction steel, to almost indestructible tool steel, which can also be hardened. Well-designed machines and other metal objects keep very long ind yield compact, powerful machines and equipment.
