Over the course of the century since Örstedt, Hall and Heroult developed the methods for producing pure aluminium, the metal has acquired an increasingly greater technical significance. Its characteristic low weight and exceptional resistance to chemical and mechanical stresses have raised aluminium to the position of being one of the most widely used materials in the design field.
Aluminium is a highly malleable material. In other words, it can be easily shaped into the specific form required. The reason for this can be ascribed to the following factors:
- The relatively low tool costs, which makes the prospect of producing special tools for extrusions adapted for a variety of purposes highly attractive.
- Short set-up times, which enable variations in batch sizes.
- High flexibility in respect of cross-sectional design.
- Relatively simple process
