Grey cast iron
Technical development demands ever better materials. These must enable reliable and efficient processing, while the material itself must also offer benefits impossible to achieve with previous materials.

The outstanding characteristics of grey cast iron include its high strength
without edge hardness and its resistance to wear.
Grey cast iron is easy to harden and process. Besides the already mentioned
properties, the wall-thickness insensitivity makes it an excellent material
which is almost unbeatable in form and function.
