SISTRAL®
SISTRAL® – Our new nano-structured high performance layer
The nanostructured high-performance coating SISTRAL® of voestalpine eifeler is the new standard for hard, dry and high-speed machining. SISTRAL® is characterized by an extremely high oxidation resistance and hot hardness. This is all thanks to its special layer structure and composition, which was developed on the new voestalpine eifeler alpha-400P coating system. These special characteristics allow a significant increase in performance with applications where standard AlTiN coatings were previously favoured.
