Fineblanking Home Overview How It Works Design Guide Submit a Drawing Contact Us


The raw material for fineblanked components is primarily rolled metal coils, although extruded and rolled strips are also used. In some cases non-metallic materials are fineblanked.

Because fineblanking is as much an extrusion process as a stamping process, the consistent flowing of material into the die cavity is critical. For this reason soft materials and materials with fine grain structure are preferred. When an application requires a hardened component, heat treatable alloys are used.

Here is a partial listing of materials that are commonly fineblanked:

  • Steels: carbon steels, alloy steels, and stainless steels.
  • Aluminum alloys
  • Copper alloys and brasses

For a more detailed listing of suitable materials, please see our Design Guide.
