Cast iron
Cast iron in its best shape
Cast iron, like steel, is a cast iron material. Its most important properties are a high degree of wear-resistance and tensile strength, as well as corrosion and temperature resilience.
Cast iron – our methods:
- Machine-moulded sand casting from 0.5 – 300 kg
- Hand-moulded sand casting up to 5,000 kg
- Commercial high-precision casting in to “wax-loss procedure” from 0.1 – 300 kg
Grey cast iron – Brief overview of the advantages:
- Good sliding properties
- Very high wear-resistance
- Extraordinarily good dampening properties
- Suitable for difficult-to-shape thin-walled workpieces
Spherical cast iron – Brief overview of the advantages:
- High tensile strength
- High material strength
- Very good tensile properties
For an overview of the cast iron qualities available from us, see the table and the material designations according to DIN EN-1561.
