Cast iron for CNC-machined machine interfaces, housings and vibration-damping structures. Gray and ductile iron have different strength and ductility. Casting condition and available machining stock influence process planning.
How should I select the grade?
Gray and ductile iron have different strength and ductility. Casting condition and available machining stock influence process planning. Material availability, stock size and certificate requirements are confirmed during quotation; a listed grade is not a stock guarantee.
What affects machining and inspection?
Review casting defects, datum selection, machining stock and sealing surfaces. Functional tolerances depend on part geometry, material condition, fixturing and measurement method, not only the material family.
What should I specify for finishing?
State the finish standard, thickness, color or texture, masking and functional surfaces. Consider coating build in fits and threads. Approve any material or finishing substitution in writing.
Material quotation checklist
Send the exact grade and condition, 2D drawing, STEP model, quantity, critical features, service environment and traceability requirements. Tecpreva can review machining suitability and proposed alternatives before production.
