One particular feature of CONIDUR® - Hole Sheets is their specific hole shape which differs from the ordinary round hole with cylindrical shape in passage direction. The holes of the CONIDUR® - Hole Sheets are more triangular to semiellipsoidal with inclined conical openings in passage direction. The upper surface of th CONIDUR® - Hole Sheets is different from its rear side. Depending on finishing of perforation one side (in most cases the working side) is scaly roughend, while the rear side is smooth. The special method of manufacturing CONIDUR® - Hole Sheets enables finishing of fines hole perforation in sheets with an initial thickness many times over the hole width. CONIDUR® - Hole Sheets are coldhardened at production achieving so a very high wear resistance which can be still improved through additional after-treatment. CONIDUR® - Hole Sheets can be processed to formed parts depending on specification.
