Cast iron
Cast iron in top form.
Like steel, cast iron belongs to the ferrous casting materials. Its most important properties are high wear resistance and tensile strength as well as corrosion and temperature resistance.
Cast iron – our methods:
- Machine-moulded sand casting from 0.5 – 300 kg
- Hand-moulded sand casting up to 5,000 kg
- Commercial precision casting using the “lost-wax process” from 0.1 – 300 kg
Grey cast iron – advantages at a glance:
- Good sliding properties
- Very high wear resistance
- Exceptionally good damping properties
- Suitable for difficult-to-mould, thin-walled workpieces
Spheroidal graphite iron – advantages at a glance:
- High tensile strength
- High material strength
- Very good elongation properties
For an overview of the cast iron qualities we supply, see the table and the material designations according to DIN EN 1561.
