Aluminum alloys for CNC-machined lightweight housings, brackets and thermal-management parts. 6061-T6 is a common general-purpose machining choice; 7075 is considered when higher strength is required. Neither is a universal substitute for the other.
How should I select the grade?
6061-T6 is a common general-purpose machining choice; 7075 is considered when higher strength is required. Neither is a universal substitute for the other. 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 temper, corrosion exposure, anodizing appearance and thin-wall stability. 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.
