A 40-50% reduction in tool-life compared to NCI can be expected. Tensile strength and ductility of ADI are near to steel, but the chip formation process classifies ADI as a ductile iron (segmented chip formation). High thermal and mechanical loads,...
Grey cast iron has the graphite in typical flake form, and the main characteristics are: low impact strength (brittle behavior); good thermal conductivity, low heat in cutting process. Grey cast iron has low impact strength, generates low cutting...
