   Spheroidal Cast Iron

Additional to the production of steel castings also spheroidal steel castings are produced at foundry Reinhard Tweer GmbH, in various qualities according to DIN EN 1563.

Spheroidal castings have a high strength and ductility because of the globular structure.
This material is used very often in vehicle industry.

Furthermore we produce bainitic cast iron (ADI) acc. DIN EN 1564.

These materials are produced on the basis of the normal spheroidal graphite casting melt by additional alloying elements and by a corresponding heat treatment. Thereby we achieve higher values regarding elongation, yield stress and tensile stress. These materials find a wide range of applications, e.g. in the automotive and engineering.
