What makes bedra a premium product? Berkenhoff: Competition: Own foundry – homogeneous initial Purchase of redrawing material – variations in microstructure, extensive alloy quality control quality Use of virgin metals – high-purity alloys Use of scrap – undesired accompanying elements Tightest alloy tolerances – highest process Wide alloy tolerances acc. to international stability standards– instable process Use of natural diamonds as drawing dies, Industrial diamonds, die polishing performed own die polishing shop – homogeneous by outside contractors – non-uniform wire surfaces surfaces Long-time annealing – gentle microstructural Fast continuous annealing – high porosity of transformation – homogeneous, fine-grained the surface, embrittlement of the wire microstructure, reliable straightness Inhouse R&D – customized alloys Production of standard alloys Reproducible quality at the highest level Variations in quality, lack of process stability Berkenhoff / 30.10.2012
